WebThe steps to replace a number of bit (s) are as follows - Take only the MSB_SIDE part and replace all the remaining bits with 0. Update the new bit sequence by adding your desired bit sequence in particular position. Update the entire bit sequence with LSB_SIDE of the original bit sequence. 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.
