C Programming Assignment Operators

What are Assignment Operators?

Assignment operators are used to assign values to variables, optionally combined with an arithmetic or bitwise operation.

List of Assignment Operators

• = — simple assignment
• += — add and assign, e.g. a += 5 is same as a = a + 5
• -= — subtract and assign
• *= — multiply and assign
• /= — divide and assign
• %= — modulus and assign
• &=, |=, ^=, <<=, >>= — bitwise assignment operators

int a = 10;
a += 5;   // a = 15
a *= 2;   // a = 30
