C - Arithmetic Operators

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

Prerequisites

• C - Datatypes

List of Arithmetic Operators

• + Addition
• - Subtraction
• * Multiplication
• / Division
• % Modulus (remainder)

Simple Example

#include <stdio.h>

int main(void) {
    int a = 15, b = 4;
    printf("a + b = %d\n", a + b);
    printf("a - b = %d\n", a - b);
    printf("a * b = %d\n", a * b);
    printf("a / b = %d\n", a / b);
    printf("a %% b = %d\n", a % b);
}

Notes

• Integer division truncates.
• % works with integers only.
