Arithmetic Operators in C Programming

What are Arithmetic Operators?

Arithmetic operators perform mathematical operations on numeric values.

List of Arithmetic Operators

• + — addition
• - — subtraction
• * — multiplication
• / — division
• % — modulus (remainder), works only with integers

int a = 10, b = 3;
printf("%d", a + b);  // 13
printf("%d", a % b);  // 1

Note on Integer Division

When both operands of / are integers, the result is truncated toward zero — 7 / 2 gives 3, not 3.5.
