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–

#include
using namespace std;
int main()
{
    //Declare two variables
    int a=20,b=5;
    //Used in Arithmetic calculations
    double product,div,rem;
    int sum,difference;
    //Perform Arithmetic calculations
    sum = a + b; // addition
    difference = a - b; // subtraction
    product = a*b; // product
    div = a/b; // divide
    rem = a%b;  // get remainder
    // Print Statements
    cout << "Sum = " << sum << endl;
    cout << "Difference = " << difference << endl;
    cout << "Product = " << product << endl;
    cout << "Division = " << div << endl;
    cout << "Modulus = " << rem << endl;
    cout << "Increment = " << ++a << endl; //pre-increment
    cout << "Decrement = " << --b << endl; //pre-decrement
    return 0;
} // end main

That’s it. Analyze the program output and understand how the operators work.
