WebTo check a bit, shift the number n to the right, then bitwise AND it: bit = (number >> n) & 1U; That will put the value of the n th bit of number into the variable bit. Changing 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); WebBit fields are the only objects that are packed within a byte. That is, two bit fields can be stored in the same byte. Bit fields can range in size from 1 to 64 bits in C or larger in C++. For big-endian mode, bit fields are packed into registers from most significant bit (MSB) to least significant bit (LSB) in the order in which they are defined.
