Common bitwise operations in c/c++

This is a resume of most common bitwise operations in c/c++. Always useful to have in hand! Extracted from here: https://stackoverflow.com/questions/47981/how-do-you-set-clear-and-toggle-a-single-bit

Setting a bit

number |= 1 << n;

Clearing a bit

number &= ~(1 << n);

Toggling a bit

number ^= 1 << n;

Checking a bit

bit = (number >> n) & 1;

Changing the nth bit to x

number = (number & ~(1 << n)) | (x << n);
