%= in c

Explanation of %= in C

The %= operator in C is the modulus assignment operator. It takes the modulus of the left operand with the right operand and assigns the result to the left operand.

For example, in the expression a %= b, the value of a would be updated to the remainder of a divided by b.

This operator combines the modulus operation and assignment operation into one. It is often used to update the value of a variable based on the remainder of a division operation.
