Submitted by **IncludeHelp**, on June 02, 2020 ## What are Arithmetic Operators in C/C++? **Arithmetic operators** are the special symbols that are used for the Arithmetic / Mathematical operations. These operators can be unary and binary. Following are the **types of Arithmetic Operators**, - Arithmetic unary operators - Arithmetic binary operators ## Arithmetic unary operators For the unary operations – we need only one operand. These are the operators, 1. Unary plus (+) 2. Unary minus (-) ### Syntax ``` +a -a ``` ### Example ``` Input: int a = -10; Operation & Output: +a = -10 -a = 10 ``` ### C++ program to demonstrate the example of arithmetic unary operators ``` #include <iostream> using namespace std; int main() { int a = 10; int b = -10; // printing the values cout << "a: " << a << endl; cout << "b: " << b << endl; // unary plus operations cout << "+a: " << +a << endl; cout << "+b: " << +b << endl; // unary minus operations cout << "-a: " << -a << endl; cout << "-b: " << -b << endl; return 0; } ``` **Output:** ``` a: 10 b: -10 +a: 10 +b: -10 -a: -10 -b: 10 ``` ## Arithmetic binary operators For the binary operations – we need two operands. These are the operators, | Operator | Name | Description | |---|---|---| | \+ | Plus operator | Returns the addition of two operands. | | \- | Minus operator | Returns the subtraction of two operands. | | \* | Multiplication operator | Returns the multiplication (product) of two operands. | | / | Divide operator | Returns the result of the division of two operands i.e. returns the quotient of the division operation. | | % | Modulus operator | Returns the remainder of the division operation on two operands. | ### Syntax ``` a + b a - b a * b a / b a % b ``` ### Example ``` Input: int a = 10; int b = 3; Operation & Output: a + b = 13 a - b = 7 a * b = 30 a / b = 3 a % b = 1 ``` ## C++ program to demonstrate the example of arithmetic binary operators ``` #include <iostream> #include <cmath> // for fmod() func. using namespace std; int main() { int a = 10; int b = 3; // printing the values cout << "a : " << a << endl; cout << "b : " << b << endl; // arithmetic operations cout << "a + b : " << a + b << endl; cout << "a - b : " << a - b << endl; cout << "a * b : " << a * b << endl; cout << "a / b : " << a / b << endl; cout << "a % b : " << a % b << endl; cout << endl; float x = 10.23f; float y = 3.10f; // printing the values cout << "x : " << x << endl; cout << "y : " << y << endl; // arithmetic operations cout << "x + y : " << x + y << endl; cout << "x - y : " << x - y << endl; cout << "x * y : " << x * y << endl; cout << "x / y : " << x / y << endl; // % operator doesn't work with float values // use fmod() for this // cout << "x % y : " << x % y << endl; cout << "fmod(" << x << " , " << y << ") : " << fmod(x, y) << endl; return 0; } ``` **Output:** ``` a : 10 b : 3 a + b : 13 a - b : 7 a * b : 30 a / b : 3 a % b : 1 x : 10.23 y : 3.1 x + y : 13.33 x - y : 7.13 x * y : 31.713 x / y : 3.3 fmod(10.23 , 3.1) : 0.93 ``` Advertisement Advertisement
