They act as potent instruments for data manipulation and control flow. For any C programmer, understanding how these operators function is essential. We'll explain the main operator classifications and their importance in this\nC Tutorial\n. To test your theoretical concepts, consider our\nC Programming Course\n.\nWhat are Operators in C language?\nOperators are special symbols used to perform various mathematical and logical operations on variables and symbols known as\noperands\n.\nThe application of operators varies depending on the context. So, it is important to understand how each type works to use them effectively when programming in C language.\nExample\n#include <stdio.h>\nint\na=\n10\n;\nint\nb=\n40\n;\nint\nc= a+b;\n11\n:\n16\nHere,\n“+”\nis an operator that performs the addition of two variables of\ndata type\nint. The variables\na\nand\nb\nare known as the operands.\nTypes of Operators in C\nC has a wide range of built-in operators that can be classified into various types according to their functionality.\nArithmetic Operators\nRelational Operators\nLogical Operators\nBitwise Operators\nAssignment Operators\nConditional Operator\nMiscellaneous Operator\nWe can further classify these operators based on the number of operands on which they operate. Now, let us go through all these operators in detail.\nRead More -\nTop 50 Mostly Asked C Interview Questions and Answers\n1. Arithmetic Operators\nThese operators perform basic mathematical operations like addition, subtraction, multiplication, and division. We will categorize the\narithmetic operators in C\ninto two categories based on the number of operands and then look at their functionality.\nType\nOperator\nName of Operator\nFunctionality\nUnary\n++\nIncrement\nIncreases the value by 1\n- -\nDecrement\nDecreases the value by 1\n+\nUnary plus\nNo change in the operand value\n-\nUnary minus\nchanges the negative number to the positive and vice-versa\nBinary\n+\nAddition\nAdd two values\n-\nSubtraction\nSubtracts one value from the other\n*\nMultiplication\nMultiplies two values\n\/\nDivision\nDivides one by the other value\n%\nModulus\nFinds the remainder after division\nExample of Arithmetic Operators in C\n#\ninclude\n<stdio.h>\nint\nmain\n()\n{\n\/\/unary operators\nint\nx =\n5\n, y=\n6\n, z=\n7\n, w=\n8\n;\nprintf\n(\n\"%d\\n\"\n, ++x);\n\/\/increments the value of x\nprintf\n(\n\"%d\\n\"\n, --y);\n\/\/decrements the value of x\nprintf\n(\n\"%d\\n\"\n, +z);\n\/\/ unary +\nprintf\n(\n\"%d\\n\"\n, -w);\n\/\/ unary - on a positive number\nprintf\n(\n\"%d\\n\"\n,-(-w));\n\/\/ unary - on a negative number\n\/\/ binary operators\nint\na =\n10\n, b =\n3\n;\nint\nsum = a + b;\nint\ndifference = a - b;\nint\nproduct = a * b;\nint\nquotient = a \/ b;\nint\nremainder = a % b;\nprintf\n(\n\"Sum: %d\\n\"\n, sum);\nprintf\n(\n\"Difference: %d\\n\"\n, difference);\nprintf\n(\n\"Product: %d\\n\"\n, product);\nprintf\n(\n\"Quotient: %d\\n\"\n, quotient);\nprintf\n(\n\"Remainder: %d\\n\"\n, remainder);\nreturn\n0\n;\r\n}\nIn the above code in the\nC Compiler\n, we have performed all the arithmetic operations on unary as well as binary operands.\nOutput\n6\n5\n7\n-\n8\n8\nSum:\n13\nDifference:\n7\nProduct:\n30\nQuotient:\n3\nRemainder:\n1\n2. Relational Operators\nRelational operators in C\nare also known as Comparison Operators. They compare the values of the two operands. The result of the comparison is either\ntrue\nor\nfalse\n. If the comparison is true, it returns 1; If the comparison results in false, it returns 0. These are known as\nboolean\nvalues.\nOperator\nName\n==\nEqual to\n>\nGreater than\n<\nLess than\n>=\nGreater than or equal to\n<=\nLess than or equal to\n!=\nNot equal to\nExample of Relational Operators in C\n#\ninclude\n<stdio.h>\nint\nmain\n()\n{\nint\nx =\n5\n;\nint\ny =\n3\n;\nprintf\n(\n\"%d\\n\"\n, x == y);\n\/\/ returns 0 (false) because 5 is not equal to 3\nprintf\n(\n\"%d\\n\"\n, x != y);\n\/\/ returns 1 (true) because 5 is not equal to 3\nprintf\n(\n\"%d\\n\"\n, x > y);\n\/\/ returns 1 (true) because 5 is greater than 3\nprintf\n(\n\"%d\\n\"\n, x < y);\n\/\/ returns 0 (false) because 5 is greater than 3\nprintf\n(\n\"%d\\n\"\n, x >= y);\n\/\/ returns 1 (true) because five is greater than, or equal, to 3\nprintf\n(\n\"%d\\n\"\n, x <= y);\n\/\/ returns 0 (false) because 5 is neither less than or equal to 3\nreturn\n0\n;\r\n}\nThe above code performs all the comparison operations and returns the result in boolean values.\nOutput\n0\n1\n1\n0\n1\n0\n3. Logical Operators\nThey are used to combine two or more conditions\/constraints. It returns either 0 or 1 depending upon whether the expression results in true or false. If the result is\ntrue\n, it returns\n1\nelse returns\n0\n.\nThe\nlogical operators in C\nare used in\ndecision-making\nand\nlooping statements\n.\nWe will categorize the logical operators into two categories based on the number of operands and then look at their functionality.\nType\nOperator\nName\nFunctionality\nBinary\n&&\nLogical AND\nreturns 1(true) if both the expressions\/values are true.\n||\nLogical OR\nreturns 1(true) if one of the expressions\/values evaluates to true.\nUnary\n!=\nLogical NOT\nNegates the expression and returns 1 or 0.\nExample of Logical Operators in\nC Online Compiler\n#\ninclude\n<stdio.h>\nint\nmain\n()\n{\nint\na =\n1\n, b =\n0\n;\nif\n(a && b)\r\n {\nprintf\n(\n\"Both a and b are true (non-zero)\\n\"\n);\r\n }\nelse\n{\nprintf\n(\n\"At least one of a or b is false (zero)\\n\"\n);\r\n }\nif\n(a || b)\r\n {\nprintf\n(\n\"At least one of a or b is true (non-zero)\\n\"\n);\r\n }\nelse\n{\nprintf\n(\n\"Both a and b are false (zero)\\n\"\n);\r\n }\nif\n(!b)\n\/\/value of b becomes 1\n{\nprintf\n(\n\"b is false (zero)\\n\"\n);\r\n }\nelse\n{\nprintf\n(\n\"b is true (non-zero)\\n\"\n);\r\n }\nreturn\n0\n;\r\n}\nThe above code performs all three logical operations on\na\nand\nb\ni.e. 1 and 0 respectively.\nOutput\nAt least one of a or b is\nfalse\n(zero)\nAt least one of a or b is\ntrue\n(non-zero)\nb is\nfalse\n(zero)\n4. Bitwise Operators\nThese operators work on individual bits. The operands are first converted into bits i.e. 0 or 1, and then the calculation is performed on them. \nWe will categorize the bitwise operators into two categories based on the number of operands and then look at their functionality.\nType\nOperator\nName\nUnary\n~\nOne's complement or Bitwise Complement\n<<\nLeft Shift\n>>\nRight Shift\nBinary\n&\nBitwise AND\n|\nBitwise OR\n^\nBitwise Exclusive OR or XOR\nWe will look at Bitwise Operators in detail in the section\nBitwise Operators in C\n5. Assignment Operators\nThese are used to assign values to the variables. The most fundamental\nassignment operator in C\nis\n“=”\n.\nExample of Assignment Operators in C\n#include <stdio.h>\nint\nmain\n()\n{\nint\nx;\r\n x =\n10\n;\n\/\/ Assigning the value 10 to x\nprintf(\n\"The value of x is: %d\\n\"\n, x);\nreturn\n0\n;}\nIn this example, we have assigned the value 10 to the variable\nx\nusing the assignment operator\n(=)\n.\nOutput\nThe value of x is:\n10\nThe following table shows some variants of the assignment operator,\n“=”\n.\nOperator\nExample\nSame as\n=\nx=y\nx=y\n+=\nx+=y\nx=x+y\n-=\nx-=y\nx=x-y\n*=\nx*=y\nx=x*y\n\/=\nx\/=y\nx=x\/y\n%=\nx%=y\nx=x%y\n&=\nx&=y\nx=x&y\n|=\nx|=y\nx=x|y\n^=\nx^=y\nx=x^y\n>>=\nx>>=y\nx=x>>y\n<<=\nx<<=y\nx=x<<y\n6. Conditional Operator\nThis is also called a\nternary operator\n. It works on three operands. The ternary operator is used to execute a set of statements when the test expression is true and another set of statements when the test expression evaluates to false.\nSyntax\ntestexpression? expression1 : expression\n2\n;\nHere, the testexpression results in a boolean value i.e. 0(true) or 1(false).\nIf the testexpression evaluates to:\nTrue:\nexpression1 before the colon\n(:)\nexecutes\nFalse:\nexpression2 after the colon\n(:)\nexecutes\nExample of Conditional Operator in C\n#\ninclude\n<stdio.h>\nint\nmain\n()\n{\nint\na =\n5\n;\nint\nb =\n10\n;\nint\nmax = (a > b) ? a : b;\nprintf\n(\n\"The maximum value is: %d\\n\"\n, max);\nreturn\n0\n;\r\n}\nOutput\nThe maximum value is:\n10\nWe will look at ternary operators in detail in the section\nTernary Operator in C\n.\n7. Miscellaneous Operator\nCommas are used to divide expressions in a statement and are a part of C's miscellaneous operator\n(,)\n. The value of the rightmost expression is returned after evaluating each expression in order from left to right.\nExample\n#\ninclude\n<stdio.h>\nint main() {\nint\na =\n5\n, b =\n10\n, c;\r\n c = (a++, b++, a + b);\nprintf\n(\n\"c = %d\\n\"\n, c);\nreturn\n0\n;}\nIn this example in the\nC Editor\n, we have shown how to combine several operations into a single statement using the comma operator. Then, it calculates the sum of\na\nand\nb\nand assigns it to\nc\nafter increasing a and b with the notations\na++\nand\nb++\n, respectively.\nOutput\nc =\n15\nPrecedence of Operators in C\nOperator precedence and associativity help us to determine which operators will be given priority when there are multiple operators in the expression. It is the grouping of terms in an expression and decides how an expression should be evaluated.\nCategory\nOperator\nAssociativity\nPostfix\n() [] ->. ++ - -\nLeft to right\nUnary\n+ - ! ~ ++ - - (type)* & sizeof\nRight to left\nMultiplicative\n* \/ %\nLeft to right\nAdditive\n+ -\nLeft to right\nShift\n<< >>\nLeft to right\nRelational\n< <= > >=\nLeft to right\nEquality\n== !=\nLeft to right\nBitwise AND\n&\nLeft to right\nBitwise XOR\n^\nLeft to right\nBitwise OR\n|\nLeft to right\nLogical AND\n&&\nLeft to right\nLogical OR\n||\nLeft to right\nConditional\n?:\nRight to left\nAssignment\n= += -= *= \/= %=>>= <<= &= ^= |=\nRight to left\nComma\n,\nLeft to right\nSummary\nC language's fundamental building block is its operators, which enable a wide range of operations. The basic kinds of operators in C, including arithmetic, relational, logical, bitwise, and assignment operators, have been outlined in this article along with examples from real-world applications for each. For easy reference, we've included a reference table to help you quickly understand operator precedence, which is essential for writing effective and error-free code. For more information, please consider our\nC Certification Course\n.\nFAQs\nThe four categories of operators in C are the arithmetic, relational, logical, and assignment operators.\nIn C, the \"&=\" operator is a compound assignment operator used to conduct a bitwise AND operation between two values and assign the result to the left operand.\nIn C, operators are used to manipulate and control data by performing various operations on it, such as calculations, comparisons, logical operations, and assignments.\nThe order in which operators are evaluated in expressions in C is determined by their operator precedence. It helps prevent confusion and make sure that expressions are accurately evaluated while adhering to mathematical norms.\nWith arithmetic operations adhering to conventional mathematical norms and logical and relational operations producing true (1) or false (0) outputs, operations in C are carried out based on operator precedence and associativity.","attrs_markdown":"[![Logo](https:\/\/www.scholarhat.com\/dist\/user\/assets\/logo-CEy3TSwt.png)ScholarHat](https:\/\/www.scholarhat.com\/)\n\n[Live Training]()\n\n[All Live

They act as potent instruments for data manipulation and control flow. For any C programmer, understanding how these operators function is essential. We'll explain the main operator classifications and their importance in this [**C Tutorial**](https:\/\/www.scholarhat.com\/tutorial\/c). To test your theoretical concepts, consider our [**C Programming Course**](https:\/\/www.scholarhat.com\/course\/c-programming-course).\n\n## What are Operators in C language?\nOperators are special symbols used to perform various mathematical and logical operations on variables and symbols known as `operands`.\n\nThe application of operators varies depending on the context. So, it is important to understand how each type works to use them effectively when programming in C language.\n\n#### Example\n```\n\n```\nHere, `“+”` is an operator that performs the addition of two variables of [**data type**](https:\/\/www.scholarhat.com\/tutorial\/c\/data-types-in-c-with-example) int. The variables `a` and `b` are known as the operands.\n\n## Types of Operators in C\nC has a wide range of built-in operators that can be classified into various types according to their functionality.\n\n1. Arithmetic Operators\n2. Relational Operators\n3. Logical Operators\n4. Bitwise Operators\n5. Assignment Operators\n6. Conditional Operator\n7. Miscellaneous Operator\n\n![Operator in C](https:\/\/dotnettrickscloud.blob.core.windows.net\/article\/c\/5620250731224228.webp)\n\nWe can further classify these operators based on the number of operands on which they operate. Now, let us go through all these operators in detail.\n\n**Read More - [Top 50 Mostly Asked C Interview Questions and Answers](https:\/\/www.scholarhat.com\/tutorial\/c\/c-interview-questions-and-answers)**\n\n### 1\\. Arithmetic Operators\nThese operators perform basic mathematical operations like addition, subtraction, multiplication, and division. We will categorize the [arithmetic operators in C](https:\/\/www.scholarhat.com\/tutorial\/c\/arithmetic-operators-in-c) into two categories based on the number of operands and then look at their functionality.\n\n|   |   |   |   |\n|---|---|---|---|\n| **Type** | **Operator** | **Name of Operator** | **Functionality** |\n| Unary | \\++ | Increment | Increases the value by 1 |\n|   | \\- - | Decrement | Decreases the value by 1 |\n|   | \\+ | Unary plus | No change in the operand value |\n|   | \\- | Unary minus | changes the negative number to the positive and vice-versa |\n| Binary | \\+ | Addition | Add two values |\n|   | \\- | Subtraction | Subtracts one value from the other |\n|   | \\* | Multiplication | Multiplies two values |\n|   | \/ | Division | Divides one by the other value |\n|   | % | Modulus | Finds the remainder after division |\n\nExample of Arithmetic Operators in C\n\n```\n\n```\nRun Code \\>\\>\n\nIn the above code in the [**C Compiler**](https:\/\/www.scholarhat.com\/compiler\/c), we have performed all the arithmetic operations on unary as well as binary operands.\n\n#### Output\n```\n\n```\n### 2\\. Relational Operators\n[Relational operators in C](https:\/\/www.scholarhat.com\/tutorial\/c\/relational-operators-in-c) are also known as Comparison Operators. They compare the values of the two operands. The result of the comparison is either `true` or `false`. If the comparison is true, it returns 1; If the comparison results in false, it returns 0. These are known as [boolean](https:\/\/www.scholarhat.com\/tutorial\/c\/boolean-and-static-in-c) values.\n\n|   |   |\n|---|---|\n| **Operator** | **Name** |\n| \\== | Equal to |\n| \\> | Greater than |\n| \\< | Less than |\n| \\>= | Greater than or equal to |\n| \\<= | Less than or equal to |\n| != | Not equal to |\n#### Example of Relational Operators in C\n```\n\n```\nRun Code \\>\\>\n\nThe above code performs all the comparison operations and returns the result in boolean values.\n\n#### Output\n```\n\n```\n### 3\\. Logical Operators\nThey are used to combine two or more conditions\/constraints. It returns either 0 or 1 depending upon whether the expression results in true or false. If the result is `true`, it returns `1` else returns `0`.\n\nThe [logical operators in C](https:\/\/www.scholarhat.com\/tutorial\/c\/c-logical-operators) are used in [decision-making](https:\/\/www.scholarhat.com\/tutorial\/c\/if-else-statements-in-c) and [looping statements](https:\/\/www.scholarhat.com\/tutorial\/c\/loops-in-c).\n\nWe will categorize the logical operators into two categories based on the number of operands and then look at their functionality.\n\n|   |   |   |   |\n|---|---|---|---|\n| **Type** | **Operator** | **Name** | **Functionality** |\n| Binary | && | Logical AND | returns 1(true) if both the expressions\/values are true. |\n|   | \\|\\| | Logical OR | returns 1(true) if one of the expressions\/values evaluates to true. |\n| Unary | != | Logical NOT | Negates the expression and returns 1 or 0. |\n#### Example of Logical Operators in [C Online Compiler](https:\/\/www.scholarhat.com\/compiler\/c)\n```\n\n```\nRun Code \\>\\>\n\nThe above code performs all three logical operations on `a` and `b` i.e. 1 and 0 respectively.\n\n#### Output\n```\nAt least one of a or b is false (zero)\r\nAt least one of a or b is true (non-zero)\r\nb is false (zero)\n```\n### 4\\. Bitwise Operators\nThese operators work on individual bits. The operands are first converted into bits i.e. 0 or 1, and then the calculation is performed on them. We will categorize the bitwise operators into two categories based on the number of operands and then look at their functionality.\n\n|   |   |   |\n|---|---|---|\n| **Type** | **Operator** | **Name** |\n| Unary | ~ | One's complement or Bitwise Complement |\n|   | \\<\\< | Left Shift |\n|   | \\>\\> | Right Shift |\n| Binary | & | Bitwise AND |\n|   | \\| | Bitwise OR |\n|   | ^ | Bitwise Exclusive OR or XOR |\n\nWe will look at Bitwise Operators in detail in the section [Bitwise Operators in C](https:\/\/www.scholarhat.com\/tutorial\/c\/bitwise-operator-in-c)\n\n### 5\\. Assignment Operators\nThese are used to assign values to the variables. The most fundamental [assignment operator in C](https:\/\/www.scholarhat.com\/tutorial\/c\/assignment-operator-in-c) is `“=”`.\n\n#### Example of Assignment Operators in C\n```\n\n```\nIn this example, we have assigned the value 10 to the variable `x` using the assignment operator **(=)**.\n\n#### Output\n```\nThe value of x is: 10\n```\nThe following table shows some variants of the assignment operator, `“=”`.\n\n|   |   |   |\n|---|---|---|\n| **Operator** | **Example** | **Same as** |\n| \\= | x=y | x=y |\n| \\+= | x+=y | x=x+y |\n| \\-= | x-=y | x=x-y |\n| \\*= | x\\*=y | x=x\\*y |\n| \/= | x\/=y | x=x\/y |\n| %= | x%=y | x=x%y |\n| &= | x&=y | x=x\\&y |\n| \\|= | x\\|=y | x=x\\|y |\n| ^= | x^=y | x=x^y |\n| \\>\\>= | x\\>\\>=y | x=x\\>\\>y |\n| \\<\\<= | x\\<\\<=y | x=x\\<\\<y |\n### 6\\. Conditional Operator\nThis is also called a `ternary operator`. It works on three operands. The ternary operator is used to execute a set of statements when the test expression is true and another set of statements when the test expression evaluates to false.\n\n#### Syntax\n```\n\n```\nHere, the testexpression results in a boolean value i.e. 0(true) or 1(false). **If the testexpression evaluates to:**\n\n- ****True:**** expression1 before the colon`(:)`executes\n- **False:** expression2 after the colon`(:)` executes\n#### Example of Conditional Operator in C\n```\n\n```\nRun Code \\>\\>\n#### Output\n```\nThe maximum value is: 10\n```\n**We will look at ternary operators in detail in the section [Ternary Operator in C](https:\/\/www.scholarhat.com\/tutorial\/c\/ternary-operator-in-C).**\n\n### 7\\. Miscellaneous Operator\nCommas are used to divide expressions in a statement and are a part of C's miscellaneous operator `(,)`. The value of the rightmost expression is returned after evaluating each expression in order from left to right.\n\n#### Example\n```\n\n```\nRun Code \\>\\>\n\nIn this example in the [**C Editor**](https:\/\/www.scholarhat.com\/compiler\/c), we have shown how to combine several operations into a single statement using the comma operator. Then, it calculates the sum of `a` and `b` and assigns it to `c` after increasing a and b with the notations `a++` and `b++`, respectively.\n\n#### Output\n```\nc = 15\n```\n## Precedence of Operators in C\nOperator precedence and associativity help us to determine which operators will be given priority when there are multiple operators in the expression. It is the grouping of terms in an expression and decides how an expression should be evaluated.\n\n|   |   |   |\n|---|---|---|\n| **Category** | **Operator** | **Associativity** |\n| Postfix | () \\[\\] -\\>. ++ - - | Left to right |\n| Unary | \\+ - ! ~ ++ - - (type)\\* & sizeof | Right to left |\n| Multiplicative | \\* \/ % | Left to right |\n| Additive | \\+ - | Left to right |\n| Shift | \\<\\< \\>\\> | Left to right |\n| Relational | \\< \\<= \\> \\>= | Left to right |\n| Equality | \\== != | Left to right |\n| Bitwise AND | & | Left to right |\n| Bitwise XOR | ^ | Left to right |\n| Bitwise OR | \\| | Left to right |\n| Logical AND | && | Left to right |\n| Logical OR | \\|\\| | Left to right |\n| Conditional | ?: | Right to left |\n| Assignment | \\= += -= \\*= \/= %=\\>\\>= \\<\\<= &= ^= \\|= | Right to left |\n| Comma | , | Left to right |\n##### Summary\nC language's fundamental building block is its operators, which enable a wide range of operations. The basic kinds of operators in C, including arithmetic, relational, logical, bitwise, and assignment operators, have been outlined in this article along with examples from real-world applications for each.

They act as potent instruments for data manipulation and control flow. For any C programmer, understanding how these operators function is essential. We'll explain the main operator classifications and their importance in this [**C Tutorial**](https:\/\/www.scholarhat.com\/tutorial\/c). To test your theoretical concepts, consider our [**C Programming Course**](https:\/\/www.scholarhat.com\/course\/c-programming-course).\n\n## What are Operators in C language?\nOperators are special symbols used to perform various mathematical and logical operations on variables and symbols known as `operands`.\n\nThe application of operators varies depending on the context. So, it is important to understand how each type works to use them effectively when programming in C language.\n\n#### Example\n```\n\n```\nHere, `“+”` is an operator that performs the addition of two variables of [**data type**](https:\/\/www.scholarhat.com\/tutorial\/c\/data-types-in-c-with-example) int. The variables `a` and `b` are known as the operands.\n\n## Types of Operators in C\nC has a wide range of built-in operators that can be classified into various types according to their functionality.\n\n1. Arithmetic Operators\n2. Relational Operators\n3. Logical Operators\n4. Bitwise Operators\n5. Assignment Operators\n6. Conditional Operator\n7. Miscellaneous Operator\n\n![Operator in C](https:\/\/dotnettrickscloud.blob.core.windows.net\/article\/c\/5620250731224228.webp)\n\nWe can further classify these operators based on the number of operands on which they operate. Now, let us go through all these operators in detail.\n\n**Read More - [Top 50 Mostly Asked C Interview Questions and Answers](https:\/\/www.scholarhat.com\/tutorial\/c\/c-interview-questions-and-answers)**\n\n### 1\\. Arithmetic Operators\nThese operators perform basic mathematical operations like addition, subtraction, multiplication, and division. We will categorize the [arithmetic operators in C](https:\/\/www.scholarhat.com\/tutorial\/c\/arithmetic-operators-in-c) into two categories based on the number of operands and then look at their functionality.\n\n|   |   |   |   |\n|---|---|---|---|\n| **Type** | **Operator** | **Name of Operator** | **Functionality** |\n| Unary | \\++ | Increment | Increases the value by 1 |\n|   | \\- - | Decrement | Decreases the value by 1 |\n|   | \\+ | Unary plus | No change in the operand value |\n|   | \\- | Unary minus | changes the negative number to the positive and vice-versa |\n| Binary | \\+ | Addition | Add two values |\n|   | \\- | Subtraction | Subtracts one value from the other |\n|   | \\* | Multiplication | Multiplies two values |\n|   | \/ | Division | Divides one by the other value |\n|   | % | Modulus | Finds the remainder after division |\n\nExample of Arithmetic Operators in C\n```\n\n```\nIn the above code in the [**C Compiler**](https:\/\/www.scholarhat.com\/compiler\/c), we have performed all the arithmetic operations on unary as well as binary operands.\n\n#### Output\n```\n\n```\n### 2\\. Relational Operators\n[Relational operators in C](https:\/\/www.scholarhat.com\/tutorial\/c\/relational-operators-in-c) are also known as Comparison Operators. They compare the values of the two operands. The result of the comparison is either `true` or `false`. If the comparison is true, it returns 1; If the comparison results in false, it returns 0. These are known as [boolean](https:\/\/www.scholarhat.com\/tutorial\/c\/boolean-and-static-in-c) values.\n\n|   |   |\n|---|---|\n| **Operator** | **Name** |\n| \\== | Equal to |\n| \\> | Greater than |\n| \\< | Less than |\n| \\>= | Greater than or equal to |\n| \\<= | Less than or equal to |\n| != | Not equal to |\n#### Example of Relational Operators in C\n```\n\n```\nThe above code performs all the comparison operations and returns the result in boolean values.\n\n#### Output\n```\n\n```\n### 3\\. Logical Operators\nThey are used to combine two or more conditions\/constraints. It returns either 0 or 1 depending upon whether the expression results in true or false. If the result is `true`, it returns `1` else returns `0`.\n\nThe [logical operators in C](https:\/\/www.scholarhat.com\/tutorial\/c\/c-logical-operators) are used in [decision-making](https:\/\/www.scholarhat.com\/tutorial\/c\/if-else-statements-in-c) and [looping statements](https:\/\/www.scholarhat.com\/tutorial\/c\/loops-in-c).\n\nWe will categorize the logical operators into two categories based on the number of operands and then look at their functionality.\n\n|   |   |   |   |\n|---|---|---|---|\n| **Type** | **Operator** | **Name** | **Functionality** |\n| Binary | && | Logical AND | returns 1(true) if both the expressions\/values are true. |\n|   | \\|\\| | Logical OR | returns 1(true) if one of the expressions\/values evaluates to true. |\n| Unary | != | Logical NOT | Negates the expression and returns 1 or 0. |\n#### Example of Logical Operators in [C Online Compiler](https:\/\/www.scholarhat.com\/compiler\/c)\n```\n\n```\nThe above code performs all three logical operations on `a` and `b` i.e. 1 and 0 respectively.\n\n#### Output\n```\nAt least one of a or b is false (zero)\r\nAt least one of a or b is true (non-zero)\r\nb is false (zero)\n```\n### 4\\. Bitwise Operators\nThese operators work on individual bits. The operands are first converted into bits i.e. 0 or 1, and then the calculation is performed on them. We will categorize the bitwise operators into two categories based on the number of operands and then look at their functionality.\n\n|   |   |   |\n|---|---|---|\n| **Type** | **Operator** | **Name** |\n| Unary | ~ | One's complement or Bitwise Complement |\n|   | \\<\\< | Left Shift |\n|   | \\>\\> | Right Shift |\n| Binary | & | Bitwise AND |\n|   | \\| | Bitwise OR |\n|   | ^ | Bitwise Exclusive OR or XOR |\n\nWe will look at Bitwise Operators in detail in the section [Bitwise Operators in C](https:\/\/www.scholarhat.com\/tutorial\/c\/bitwise-operator-in-c)\n\n### 5\\. Assignment Operators\nThese are used to assign values to the variables. The most fundamental [assignment operator in C](https:\/\/www.scholarhat.com\/tutorial\/c\/assignment-operator-in-c) is `“=”`.\n\n#### Example of Assignment Operators in C\n```\n\n```\nIn this example, we have assigned the value 10 to the variable `x` using the assignment operator **(=)**.\n\n#### Output\n```\nThe value of x is: 10\n```\nThe following table shows some variants of the assignment operator, `“=”`.\n\n|   |   |   |\n|---|---|---|\n| **Operator** | **Example** | **Same as** |\n| \\= | x=y | x=y |\n| \\+= | x+=y | x=x+y |\n| \\-= | x-=y | x=x-y |\n| \\*= | x\\*=y | x=x\\*y |\n| \/= | x\/=y | x=x\/y |\n| %= | x%=y | x=x%y |\n| &= | x&=y | x=x\\&y |\n| \\|= | x\\|=y | x=x\\|y |\n| ^= | x^=y | x=x^y |\n| \\>\\>= | x\\>\\>=y | x=x\\>\\>y |\n| \\<\\<= | x\\<\\<=y | x=x\\<\\<y |\n### 6\\. Conditional Operator\nThis is also called a `ternary operator`. It works on three operands. The ternary operator is used to execute a set of statements when the test expression is true and another set of statements when the test expression evaluates to false.\n\n#### Syntax\n```\n\n```\nHere, the testexpression results in a boolean value i.e. 0(true) or 1(false). **If the testexpression evaluates to:**\n\n- ****True:**** expression1 before the colon`(:)`executes\n- **False:** expression2 after the colon`(:)` executes\n#### Example of Conditional Operator in C\n```\n\n```\n#### Output\n```\nThe maximum value is: 10\n```\n**We will look at ternary operators in detail in the section [Ternary Operator in C](https:\/\/www.scholarhat.com\/tutorial\/c\/ternary-operator-in-C).**\n\n### 7\\. Miscellaneous Operator\nCommas are used to divide expressions in a statement and are a part of C's miscellaneous operator `(,)`. The value of the rightmost expression is returned after evaluating each expression in order from left to right.\n\n#### Example\n```\n\n```\nIn this example in the [**C Editor**](https:\/\/www.scholarhat.com\/compiler\/c), we have shown how to combine several operations into a single statement using the comma operator. Then, it calculates the sum of `a` and `b` and assigns it to `c` after increasing a and b with the notations `a++` and `b++`, respectively.\n\n#### Output\n```\nc = 15\n```\n## Precedence of Operators in C\nOperator precedence and associativity help us to determine which operators will be given priority when there are multiple operators in the expression. It is the grouping of terms in an expression and decides how an expression should be evaluated.\n\n|   |   |   |\n|---|---|---|\n| **Category** | **Operator** | **Associativity** |\n| Postfix | () \\[\\] -\\>. ++ - - | Left to right |\n| Unary | \\+ - ! ~ ++ - - (type)\\* & sizeof | Right to left |\n| Multiplicative | \\* \/ % | Left to right |\n| Additive | \\+ - | Left to right |\n| Shift | \\<\\< \\>\\> | Left to right |\n| Relational | \\< \\<= \\> \\>= | Left to right |\n| Equality | \\== != | Left to right |\n| Bitwise AND | & | Left to right |\n| Bitwise XOR | ^ | Left to right |\n| Bitwise OR | \\| | Left to right |\n| Logical AND | && | Left to right |\n| Logical OR | \\|\\| | Left to right |\n| Conditional | ?: | Right to left |\n| Assignment | \\= += -= \\*= \/= %=\\>\\>= \\<\\<= &= ^= \\|= | Right to left |\n| Comma | , | Left to right |\n##### Summary\nC language's fundamental building block is its operators, which enable a wide range of operations.

Boilerpipe Text	Operators in C: An Overview Operators in C constitute the building block of the C Programming Language Online Course Free . They act as potent instruments for data manipulation and control flow. For any C programmer, understanding how these operators function is essential. We'll explain the main operator classifications and their importance in this C Tutorial . To test your theoretical concepts, consider our C Programming Course . What are Operators in C language? Operators are special symbols used to perform various mathematical and logical operations on variables and symbols known as operands . The application of operators varies depending on the context. So, it is important to understand how each type works to use them effectively when programming in C language. Example #include <stdio.h> int a= 10 ; int b= 40 ; int c= a+b; 11 : 16 Here, “+” is an operator that performs the addition of two variables of data type int. The variables a and b are known as the operands. Types of Operators in C C has a wide range of built-in operators that can be classified into various types according to their functionality. Arithmetic Operators Relational Operators Logical Operators Bitwise Operators Assignment Operators Conditional Operator Miscellaneous Operator We can further classify these operators based on the number of operands on which they operate. Now, let us go through all these operators in detail. Read More - Top 50 Mostly Asked C Interview Questions and Answers 1. Arithmetic Operators These operators perform basic mathematical operations like addition, subtraction, multiplication, and division. We will categorize the arithmetic operators in C into two categories based on the number of operands and then look at their functionality. Type Operator Name of Operator Functionality Unary ++ Increment Increases the value by 1 - - Decrement Decreases the value by 1 + Unary plus No change in the operand value - Unary minus changes the negative number to the positive and vice-versa Binary + Addition Add two values - Subtraction Subtracts one value from the other * Multiplication Multiplies two values / Division Divides one by the other value % Modulus Finds the remainder after division Example of Arithmetic Operators in C # include <stdio.h> int main () { //unary operators int x = 5 , y= 6 , z= 7 , w= 8 ; printf ( "%d\n" , ++x); //increments the value of x printf ( "%d\n" , --y); //decrements the value of x printf ( "%d\n" , +z); // unary + printf ( "%d\n" , -w); // unary - on a positive number printf ( "%d\n" ,-(-w)); // unary - on a negative number // binary operators int a = 10 , b = 3 ; int sum = a + b; int difference = a - b; int product = a * b; int quotient = a / b; int remainder = a % b; printf ( "Sum: %d\n" , sum); printf ( "Difference: %d\n" , difference); printf ( "Product: %d\n" , product); printf ( "Quotient: %d\n" , quotient); printf ( "Remainder: %d\n" , remainder); return 0 ; } In the above code in the C Compiler , we have performed all the arithmetic operations on unary as well as binary operands. Output 6 5 7 - 8 8 Sum: 13 Difference: 7 Product: 30 Quotient: 3 Remainder: 1 2. Relational Operators Relational operators in C are also known as Comparison Operators. They compare the values of the two operands. The result of the comparison is either true or false . If the comparison is true, it returns 1; If the comparison results in false, it returns 0. These are known as boolean values. Operator Name == Equal to > Greater than < Less than >= Greater than or equal to <= Less than or equal to != Not equal to Example of Relational Operators in C # include <stdio.h> int main () { int x = 5 ; int y = 3 ; printf ( "%d\n" , x == y); // returns 0 (false) because 5 is not equal to 3 printf ( "%d\n" , x != y); // returns 1 (true) because 5 is not equal to 3 printf ( "%d\n" , x > y); // returns 1 (true) because 5 is greater than 3 printf ( "%d\n" , x < y); // returns 0 (false) because 5 is greater than 3 printf ( "%d\n" , x >= y); // returns 1 (true) because five is greater than, or equal, to 3 printf ( "%d\n" , x <= y); // returns 0 (false) because 5 is neither less than or equal to 3 return 0 ; } The above code performs all the comparison operations and returns the result in boolean values. Output 0 1 1 0 1 0 3. Logical Operators They are used to combine two or more conditions/constraints. It returns either 0 or 1 depending upon whether the expression results in true or false. If the result is true , it returns 1 else returns 0 . The logical operators in C are used in decision-making and looping statements . We will categorize the logical operators into two categories based on the number of operands and then look at their functionality. Type Operator Name Functionality Binary && Logical AND returns 1(true) if both the expressions/values are true. \|\| Logical OR returns 1(true) if one of the expressions/values evaluates to true. Unary != Logical NOT Negates the expression and returns 1 or 0. Example of Logical Operators in C Online Compiler # include <stdio.h> int main () { int a = 1 , b = 0 ; if (a && b) { printf ( "Both a and b are true (non-zero)\n" ); } else { printf ( "At least one of a or b is false (zero)\n" ); } if (a \|\| b) { printf ( "At least one of a or b is true (non-zero)\n" ); } else { printf ( "Both a and b are false (zero)\n" ); } if (!b) //value of b becomes 1 { printf ( "b is false (zero)\n" ); } else { printf ( "b is true (non-zero)\n" ); } return 0 ; } The above code performs all three logical operations on a and b i.e. 1 and 0 respectively. Output At least one of a or b is false (zero) At least one of a or b is true (non-zero) b is false (zero) 4. Bitwise Operators These operators work on individual bits. The operands are first converted into bits i.e. 0 or 1, and then the calculation is performed on them. We will categorize the bitwise operators into two categories based on the number of operands and then look at their functionality. Type Operator Name Unary ~ One's complement or Bitwise Complement << Left Shift >> Right Shift Binary & Bitwise AND \| Bitwise OR ^ Bitwise Exclusive OR or XOR We will look at Bitwise Operators in detail in the section Bitwise Operators in C 5. Assignment Operators These are used to assign values to the variables. The most fundamental assignment operator in C is “=” . Example of Assignment Operators in C #include <stdio.h> int main () { int x; x = 10 ; // Assigning the value 10 to x printf( "The value of x is: %d\n" , x); return 0 ;} In this example, we have assigned the value 10 to the variable x using the assignment operator (=) . Output The value of x is: 10 The following table shows some variants of the assignment operator, “=” . Operator Example Same as = x=y x=y += x+=y x=x+y -= x-=y x=x-y = x=y x=xy /= x/=y x=x/y %= x%=y x=x%y &= x&=y x=x&y \|= x\|=y x=x\|y ^= x^=y x=x^y >>= x>>=y x=x>>y <<= x<<=y x=x<<y 6. Conditional Operator This is also called a ternary operator . It works on three operands. The ternary operator is used to execute a set of statements when the test expression is true and another set of statements when the test expression evaluates to false. Syntax testexpression? expression1 : expression 2 ; Here, the testexpression results in a boolean value i.e. 0(true) or 1(false). If the testexpression evaluates to: True: expression1 before the colon (:) executes False: expression2 after the colon (:) executes Example of Conditional Operator in C # include <stdio.h> int main () { int a = 5 ; int b = 10 ; int max = (a > b) ? a : b; printf ( "The maximum value is: %d\n" , max); return 0 ; } Output The maximum value is: 10 We will look at ternary operators in detail in the section Ternary Operator in C . 7. Miscellaneous Operator Commas are used to divide expressions in a statement and are a part of C's miscellaneous operator (,) . The value of the rightmost expression is returned after evaluating each expression in order from left to right. Example # include <stdio.h> int main() { int a = 5 , b = 10 , c; c = (a++, b++, a + b); printf ( "c = %d\n" , c); return 0 ;} In this example in the C Editor , we have shown how to combine several operations into a single statement using the comma operator. Then, it calculates the sum of a and b and assigns it to c after increasing a and b with the notations a++ and b++ , respectively. Output c = 15 Precedence of Operators in C Operator precedence and associativity help us to determine which operators will be given priority when there are multiple operators in the expression. It is the grouping of terms in an expression and decides how an expression should be evaluated. Category Operator Associativity Postfix () [] ->. ++ - - Left to right Unary + - ! ~ ++ - - (type) & sizeof Right to left Multiplicative * / % Left to right Additive + - Left to right Shift << >> Left to right Relational < <= > >= Left to right Equality == != Left to right Bitwise AND & Left to right Bitwise XOR ^ Left to right Bitwise OR \| Left to right Logical AND && Left to right Logical OR \|\| Left to right Conditional ?: Right to left Assignment = += -= *= /= %=>>= <<= &= ^= \|= Right to left Comma , Left to right Summary C language's fundamental building block is its operators, which enable a wide range of operations. The basic kinds of operators in C, including arithmetic, relational, logical, bitwise, and assignment operators, have been outlined in this article along with examples from real-world applications for each. For easy reference, we've included a reference table to help you quickly understand operator precedence, which is essential for writing effective and error-free code. For more information, please consider our C Certification Course . FAQs The four categories of operators in C are the arithmetic, relational, logical, and assignment operators. In C, the "&=" operator is a compound assignment operator used to conduct a bitwise AND operation between two values and assign the result to the left operand. In C, operators are used to manipulate and control data by performing various operations on it, such as calculations, comparisons, logical operations, and assignments. The order in which operators are evaluated in expressions in C is determined by their operator precedence. It helps prevent confusion and make sure that expressions are accurately evaluated while adhering to mathematical norms. With arithmetic operations adhering to conventional mathematical norms and logical and relational operations producing true (1) or false (0) outputs, operations in C are carried out based on operator precedence and associativity.

They act as potent instruments for data manipulation and control flow. For any C programmer, understanding how these operators function is essential. We'll explain the main operator classifications and their importance in this [C Tutorial](https://www.scholarhat.com/tutorial/c). To test your theoretical concepts, consider our [C Programming Course](https://www.scholarhat.com/course/c-programming-course). ## What are Operators in C language? Operators are special symbols used to perform various mathematical and logical operations on variables and symbols known as `operands`. The application of operators varies depending on the context. So, it is important to understand how each type works to use them effectively when programming in C language. #### Example ``` ``` Here, `“+”` is an operator that performs the addition of two variables of [data type](https://www.scholarhat.com/tutorial/c/data-types-in-c-with-example) int. The variables `a` and `b` are known as the operands. ## Types of Operators in C C has a wide range of built-in operators that can be classified into various types according to their functionality. 1. Arithmetic Operators 2. Relational Operators 3. Logical Operators 4. Bitwise Operators 5. Assignment Operators 6. Conditional Operator 7. Miscellaneous Operator ![Operator in C](https://dotnettrickscloud.blob.core.windows.net/article/c/5620250731224228.webp) We can further classify these operators based on the number of operands on which they operate. Now, let us go through all these operators in detail. Read More - [Top 50 Mostly Asked C Interview Questions and Answers](https://www.scholarhat.com/tutorial/c/c-interview-questions-and-answers) ### 1\. Arithmetic Operators These operators perform basic mathematical operations like addition, subtraction, multiplication, and division. We will categorize the [arithmetic operators in C](https://www.scholarhat.com/tutorial/c/arithmetic-operators-in-c) into two categories based on the number of operands and then look at their functionality. \| \| \| \| \| \|---\|---\|---\|---\| \| Type \| Operator \| Name of Operator \| Functionality \| \| Unary \| \++ \| Increment \| Increases the value by 1 \| \| \| \- - \| Decrement \| Decreases the value by 1 \| \| \| \+ \| Unary plus \| No change in the operand value \| \| \| \- \| Unary minus \| changes the negative number to the positive and vice-versa \| \| Binary \| \+ \| Addition \| Add two values \| \| \| \- \| Subtraction \| Subtracts one value from the other \| \| \| \* \| Multiplication \| Multiplies two values \| \| \| / \| Division \| Divides one by the other value \| \| \| % \| Modulus \| Finds the remainder after division \| Example of Arithmetic Operators in C ``` ``` Run Code \>\> In the above code in the [C Compiler](https://www.scholarhat.com/compiler/c), we have performed all the arithmetic operations on unary as well as binary operands. #### Output ``` ``` ### 2\. Relational Operators [Relational operators in C](https://www.scholarhat.com/tutorial/c/relational-operators-in-c) are also known as Comparison Operators. They compare the values of the two operands. The result of the comparison is either `true` or `false`. If the comparison is true, it returns 1; If the comparison results in false, it returns 0. These are known as [boolean](https://www.scholarhat.com/tutorial/c/boolean-and-static-in-c) values. \| \| \| \|---\|---\| \| Operator \| Name \| \| \== \| Equal to \| \| \> \| Greater than \| \| \< \| Less than \| \| \>= \| Greater than or equal to \| \| \<= \| Less than or equal to \| \| != \| Not equal to \| #### Example of Relational Operators in C ``` ``` Run Code \>\> The above code performs all the comparison operations and returns the result in boolean values. #### Output ``` ``` ### 3\. Logical Operators They are used to combine two or more conditions/constraints. It returns either 0 or 1 depending upon whether the expression results in true or false. If the result is `true`, it returns `1` else returns `0`. The [logical operators in C](https://www.scholarhat.com/tutorial/c/c-logical-operators) are used in [decision-making](https://www.scholarhat.com/tutorial/c/if-else-statements-in-c) and [looping statements](https://www.scholarhat.com/tutorial/c/loops-in-c). We will categorize the logical operators into two categories based on the number of operands and then look at their functionality. \| \| \| \| \| \|---\|---\|---\|---\| \| Type \| Operator \| Name \| Functionality \| \| Binary \| && \| Logical AND \| returns 1(true) if both the expressions/values are true. \| \| \| \\|\\| \| Logical OR \| returns 1(true) if one of the expressions/values evaluates to true. \| \| Unary \| != \| Logical NOT \| Negates the expression and returns 1 or 0. \| #### Example of Logical Operators in [C Online Compiler](https://www.scholarhat.com/compiler/c) ``` ``` Run Code \>\> The above code performs all three logical operations on `a` and `b` i.e. 1 and 0 respectively. #### Output ``` At least one of a or b is false (zero) At least one of a or b is true (non-zero) b is false (zero) ``` ### 4\. Bitwise Operators These operators work on individual bits. The operands are first converted into bits i.e. 0 or 1, and then the calculation is performed on them. We will categorize the bitwise operators into two categories based on the number of operands and then look at their functionality. \| \| \| \| \|---\|---\|---\| \| Type \| Operator \| Name \| \| Unary \| ~ \| One's complement or Bitwise Complement \| \| \| \<\< \| Left Shift \| \| \| \>\> \| Right Shift \| \| Binary \| & \| Bitwise AND \| \| \| \\| \| Bitwise OR \| \| \| ^ \| Bitwise Exclusive OR or XOR \| We will look at Bitwise Operators in detail in the section [Bitwise Operators in C](https://www.scholarhat.com/tutorial/c/bitwise-operator-in-c) ### 5\. Assignment Operators These are used to assign values to the variables. The most fundamental [assignment operator in C](https://www.scholarhat.com/tutorial/c/assignment-operator-in-c) is `“=”`. #### Example of Assignment Operators in C ``` ``` In this example, we have assigned the value 10 to the variable `x` using the assignment operator (=). #### Output ``` The value of x is: 10 ``` The following table shows some variants of the assignment operator, `“=”`. \| \| \| \| \|---\|---\|---\| \| Operator \| Example \| Same as \| \| \= \| x=y \| x=y \| \| \+= \| x+=y \| x=x+y \| \| \-= \| x-=y \| x=x-y \| \| \= \| x\=y \| x=x\y \| \| /= \| x/=y \| x=x/y \| \| %= \| x%=y \| x=x%y \| \| &= \| x&=y \| x=x\&y \| \| \\|= \| x\\|=y \| x=x\\|y \| \| ^= \| x^=y \| x=x^y \| \| \>\>= \| x\>\>=y \| x=x\>\>y \| \| \<\<= \| x\<\<=y \| x=x\<\<y \| ### 6\. Conditional Operator This is also called a `ternary operator`. It works on three operands. The ternary operator is used to execute a set of statements when the test expression is true and another set of statements when the test expression evaluates to false. #### Syntax ``` ``` Here, the testexpression results in a boolean value i.e. 0(true) or 1(false). If the testexpression evaluates to:* - **True: expression1 before the colon`(:)`executes - False: expression2 after the colon`(:)` executes #### Example of Conditional Operator in C ``` ``` Run Code \>\> #### Output ``` The maximum value is: 10 ``` We will look at ternary operators in detail in the section [Ternary Operator in C](https://www.scholarhat.com/tutorial/c/ternary-operator-in-C). ### 7\. Miscellaneous Operator Commas are used to divide expressions in a statement and are a part of C's miscellaneous operator `(,)`. The value of the rightmost expression is returned after evaluating each expression in order from left to right. #### Example ``` ``` Run Code \>\> In this example in the [C Editor](https://www.scholarhat.com/compiler/c), we have shown how to combine several operations into a single statement using the comma operator. Then, it calculates the sum of `a` and `b` and assigns it to `c` after increasing a and b with the notations `a++` and `b++`, respectively. #### Output ``` c = 15 ``` ## Precedence of Operators in C Operator precedence and associativity help us to determine which operators will be given priority when there are multiple operators in the expression. It is the grouping of terms in an expression and decides how an expression should be evaluated. \| \| \| \| \|---\|---\|---\| \| Category \| Operator \| Associativity** \| \| Postfix \| () \[\] -\>. ++ - - \| Left to right \| \| Unary \| \+ - ! ~ ++ - - (type)\* & sizeof \| Right to left \| \| Multiplicative \| \* / % \| Left to right \| \| Additive \| \+ - \| Left to right \| \| Shift \| \<\< \>\> \| Left to right \| \| Relational \| \< \<= \> \>= \| Left to right \| \| Equality \| \== != \| Left to right \| \| Bitwise AND \| & \| Left to right \| \| Bitwise XOR \| ^ \| Left to right \| \| Bitwise OR \| \\| \| Left to right \| \| Logical AND \| && \| Left to right \| \| Logical OR \| \\|\\| \| Left to right \| \| Conditional \| ?: \| Right to left \| \| Assignment \| \= += -= \= /= %=\>\>= \<\<= &= ^= \\|= \| Right to left \| \| Comma \| , \| Left to right \| ##### Summary C language's fundamental building block is its operators, which enable a wide range of operations. The basic kinds of operators in C, including arithmetic, relational, logical, bitwise, and assignment operators, have been outlined in this article along with examples from real-world applications for each. For easy reference, we've included a reference table to help you quickly understand operator precedence, which is essential for writing effective and error-free code. For more information, please consider our [C Certification Course](https://www.scholarhat.com/course/c-programming-course). ### FAQs ### Q1. What are the four types of operators in C?

They act as potent instruments for data manipulation and control flow. For any C programmer, understanding how these operators function is essential. We'll explain the main operator classifications and their importance in this [C Tutorial](https://www.scholarhat.com/tutorial/c). To test your theoretical concepts, consider our [C Programming Course](https://www.scholarhat.com/course/c-programming-course). ## What are Operators in C language? Operators are special symbols used to perform various mathematical and logical operations on variables and symbols known as `operands`. The application of operators varies depending on the context. So, it is important to understand how each type works to use them effectively when programming in C language. #### Example ``` ``` Here, `“+”` is an operator that performs the addition of two variables of [data type](https://www.scholarhat.com/tutorial/c/data-types-in-c-with-example) int. The variables `a` and `b` are known as the operands. ## Types of Operators in C C has a wide range of built-in operators that can be classified into various types according to their functionality. 1. Arithmetic Operators 2. Relational Operators 3. Logical Operators 4. Bitwise Operators 5. Assignment Operators 6. Conditional Operator 7. Miscellaneous Operator ![Operator in C](https://dotnettrickscloud.blob.core.windows.net/article/c/5620250731224228.webp) We can further classify these operators based on the number of operands on which they operate. Now, let us go through all these operators in detail. Read More - [Top 50 Mostly Asked C Interview Questions and Answers](https://www.scholarhat.com/tutorial/c/c-interview-questions-and-answers) ### 1\. Arithmetic Operators These operators perform basic mathematical operations like addition, subtraction, multiplication, and division. We will categorize the [arithmetic operators in C](https://www.scholarhat.com/tutorial/c/arithmetic-operators-in-c) into two categories based on the number of operands and then look at their functionality. \| \| \| \| \| \|---\|---\|---\|---\| \| Type \| Operator \| Name of Operator \| Functionality \| \| Unary \| \++ \| Increment \| Increases the value by 1 \| \| \| \- - \| Decrement \| Decreases the value by 1 \| \| \| \+ \| Unary plus \| No change in the operand value \| \| \| \- \| Unary minus \| changes the negative number to the positive and vice-versa \| \| Binary \| \+ \| Addition \| Add two values \| \| \| \- \| Subtraction \| Subtracts one value from the other \| \| \| \* \| Multiplication \| Multiplies two values \| \| \| / \| Division \| Divides one by the other value \| \| \| % \| Modulus \| Finds the remainder after division \| Example of Arithmetic Operators in C ``` ``` In the above code in the [C Compiler](https://www.scholarhat.com/compiler/c), we have performed all the arithmetic operations on unary as well as binary operands. #### Output ``` ``` ### 2\. Relational Operators [Relational operators in C](https://www.scholarhat.com/tutorial/c/relational-operators-in-c) are also known as Comparison Operators. They compare the values of the two operands. The result of the comparison is either `true` or `false`. If the comparison is true, it returns 1; If the comparison results in false, it returns 0. These are known as [boolean](https://www.scholarhat.com/tutorial/c/boolean-and-static-in-c) values. \| \| \| \|---\|---\| \| Operator \| Name \| \| \== \| Equal to \| \| \> \| Greater than \| \| \< \| Less than \| \| \>= \| Greater than or equal to \| \| \<= \| Less than or equal to \| \| != \| Not equal to \| #### Example of Relational Operators in C ``` ``` The above code performs all the comparison operations and returns the result in boolean values. #### Output ``` ``` ### 3\. Logical Operators They are used to combine two or more conditions/constraints. It returns either 0 or 1 depending upon whether the expression results in true or false. If the result is `true`, it returns `1` else returns `0`. The [logical operators in C](https://www.scholarhat.com/tutorial/c/c-logical-operators) are used in [decision-making](https://www.scholarhat.com/tutorial/c/if-else-statements-in-c) and [looping statements](https://www.scholarhat.com/tutorial/c/loops-in-c). We will categorize the logical operators into two categories based on the number of operands and then look at their functionality. \| \| \| \| \| \|---\|---\|---\|---\| \| Type \| Operator \| Name \| Functionality \| \| Binary \| && \| Logical AND \| returns 1(true) if both the expressions/values are true. \| \| \| \\|\\| \| Logical OR \| returns 1(true) if one of the expressions/values evaluates to true. \| \| Unary \| != \| Logical NOT \| Negates the expression and returns 1 or 0. \| #### Example of Logical Operators in [C Online Compiler](https://www.scholarhat.com/compiler/c) ``` ``` The above code performs all three logical operations on `a` and `b` i.e. 1 and 0 respectively. #### Output ``` At least one of a or b is false (zero) At least one of a or b is true (non-zero) b is false (zero) ``` ### 4\. Bitwise Operators These operators work on individual bits. The operands are first converted into bits i.e. 0 or 1, and then the calculation is performed on them. We will categorize the bitwise operators into two categories based on the number of operands and then look at their functionality. \| \| \| \| \|---\|---\|---\| \| Type \| Operator \| Name \| \| Unary \| ~ \| One's complement or Bitwise Complement \| \| \| \<\< \| Left Shift \| \| \| \>\> \| Right Shift \| \| Binary \| & \| Bitwise AND \| \| \| \\| \| Bitwise OR \| \| \| ^ \| Bitwise Exclusive OR or XOR \| We will look at Bitwise Operators in detail in the section [Bitwise Operators in C](https://www.scholarhat.com/tutorial/c/bitwise-operator-in-c) ### 5\. Assignment Operators These are used to assign values to the variables. The most fundamental [assignment operator in C](https://www.scholarhat.com/tutorial/c/assignment-operator-in-c) is `“=”`. #### Example of Assignment Operators in C ``` ``` In this example, we have assigned the value 10 to the variable `x` using the assignment operator (=). #### Output ``` The value of x is: 10 ``` The following table shows some variants of the assignment operator, `“=”`. \| \| \| \| \|---\|---\|---\| \| Operator \| Example \| Same as \| \| \= \| x=y \| x=y \| \| \+= \| x+=y \| x=x+y \| \| \-= \| x-=y \| x=x-y \| \| \= \| x\=y \| x=x\y \| \| /= \| x/=y \| x=x/y \| \| %= \| x%=y \| x=x%y \| \| &= \| x&=y \| x=x\&y \| \| \\|= \| x\\|=y \| x=x\\|y \| \| ^= \| x^=y \| x=x^y \| \| \>\>= \| x\>\>=y \| x=x\>\>y \| \| \<\<= \| x\<\<=y \| x=x\<\<y \| ### 6\. Conditional Operator This is also called a `ternary operator`. It works on three operands. The ternary operator is used to execute a set of statements when the test expression is true and another set of statements when the test expression evaluates to false. #### Syntax ``` ``` Here, the testexpression results in a boolean value i.e. 0(true) or 1(false). If the testexpression evaluates to:* - **True: expression1 before the colon`(:)`executes - False: expression2 after the colon`(:)` executes #### Example of Conditional Operator in C ``` ``` #### Output ``` The maximum value is: 10 ``` We will look at ternary operators in detail in the section [Ternary Operator in C](https://www.scholarhat.com/tutorial/c/ternary-operator-in-C). ### 7\. Miscellaneous Operator Commas are used to divide expressions in a statement and are a part of C's miscellaneous operator `(,)`. The value of the rightmost expression is returned after evaluating each expression in order from left to right. #### Example ``` ``` In this example in the [C Editor](https://www.scholarhat.com/compiler/c), we have shown how to combine several operations into a single statement using the comma operator. Then, it calculates the sum of `a` and `b` and assigns it to `c` after increasing a and b with the notations `a++` and `b++`, respectively. #### Output ``` c = 15 ``` ## Precedence of Operators in C Operator precedence and associativity help us to determine which operators will be given priority when there are multiple operators in the expression. It is the grouping of terms in an expression and decides how an expression should be evaluated. \| \| \| \| \|---\|---\|---\| \| Category \| Operator \| Associativity** \| \| Postfix \| () \[\] -\>. ++ - - \| Left to right \| \| Unary \| \+ - ! ~ ++ - - (type)\* & sizeof \| Right to left \| \| Multiplicative \| \* / % \| Left to right \| \| Additive \| \+ - \| Left to right \| \| Shift \| \<\< \>\> \| Left to right \| \| Relational \| \< \<= \> \>= \| Left to right \| \| Equality \| \== != \| Left to right \| \| Bitwise AND \| & \| Left to right \| \| Bitwise XOR \| ^ \| Left to right \| \| Bitwise OR \| \\| \| Left to right \| \| Logical AND \| && \| Left to right \| \| Logical OR \| \\|\\| \| Left to right \| \| Conditional \| ?: \| Right to left \| \| Assignment \| \= += -= \= /= %=\>\>= \<\<= &= ^= \\|= \| Right to left \| \| Comma \| , \| Left to right \| ##### Summary C language's fundamental building block is its operators, which enable a wide range of operations. The basic kinds of operators in C, including arithmetic, relational, logical, bitwise, and assignment operators, have been outlined in this article along with examples from real-world applications for each. For easy reference, we've included a reference table to help you quickly understand operator precedence, which is essential for writing effective and error-free code. For more information, please consider our [C Certification Course*](https://www.scholarhat.com/course/c-programming-course). ### FAQs The four categories of operators in C are the arithmetic, relational, logical, and assignment operators. In C, the "&=" operator is a compound assignment operator used to conduct a bitwise AND operation between two values and assign the result to the left operand. In C, operators are used to manipulate and control data by performing various operations on it, such as calculations, comparisons, logical operations, and assignments. The order in which operators are evaluated in expressions in C is determined by their operator precedence. It helps prevent confusion and make sure that expressions are accurately evaluated while adhering to mathematical norms. With arithmetic operations adhering to conventional mathematical norms and logical and relational operations producing true (1) or false (0) outputs, operations in C are carried out based on operator precedence and associativity.
