What is an arithmetic operator? An arithmetic operator is an calculate operator like: Add, Subtract, Multiply, Divide, Modulus, and Increase of Decrease operator. There are following arithmetic operators supported by C++ language Example 1: Declaration variable for follow operator bellow int A=10, B=20; Example 2: Using variable with operator and display the result 3.1.Arithmetic Operators
Operator
Description
Example
+
Adds two operands
A + B will give 30
–
Subtracts second operand from the first
A – B will give -10
*
Multiplies both operands
A * B will give 200
/
Divides numerator by de-numerator
B / A will give 2
%
Modulus Operator and remainder of after an integer division
B % A will give 0
++
Increment operator, increases integer value by one
A++ will give 11
—
Decrement operator, decreases integer value by one
A– will give 9
