WebChanging the n th bit to x. Setting the n th bit to either 1 or 0 can be achieved with the following on a 2's complement C++ implementation: number ^= (-x ^ number) & (1UL << n); Bit n will be set if x is 1, and cleared if x is 0. If x has some other value, you get garbage. x = !!x will booleanize it to 0 or 1.
