C++ Arithmetic Operators

Overview

In this tutorial, we will learn about C++ Arithmetic Operators with a sample program. Arithmetic operators are used to performing arithmetic calculations.

C++ Arithmetic Operators

Operation	Operator	Description	Sample Example
Addition	+	Adds the two operands	sum = a + b
Subtraction	–	Subtracts the second operand from the first operand	diff = a – b
Multiplication	*	Multiplies the two operands	product = a * b
Division	/	Divides the numerator by the denominator	div = a/b
Modulus	%	The remainder of the integer division	a%b
Increment	++	Increments the value of the operand by 1	i++
Decrement	—	Decrements the value of the operand by 1	j–
