C++ Arithmetic Operators

C++ Arithmetic Operators

Arithmetic operators in C++ are used to perform basic mathematical operations such as addition, subtraction, multiplication, and division.

List of Arithmetic Operators

Operator	Description	Example
+	Addition	int sum = 5 + 3; // sum = 8
–	Subtraction	int diff = 5 – 3; // diff = 2
*	Multiplication	int prod = 5 * 3; // prod = 15
/	Division	int div = 10 / 2; // div = 5
%	Modulus (remainder after division)	int rem = 10 % 3; // rem = 1
++	Increment (adds 1 to a variable)	int x = 5; x++; // x = 6
—	Decrement (subtracts 1 from a variable)	int x = 5; x–; // x = 4

Example Program

#include <iostream>
using namespace std;

int main() {

    int a = 10, b = 3;

    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;

    a++;
    cout << "a after increment: " << a << endl;

    b--;
    cout << "b after decrement: " << b << endl;

    return 0;
}

Output

a + b = 13
a - b = 7
a * b = 30
a / b = 3
a % b = 1
a after increment: 11
b after decrement: 2
