WebTo reset a bit, the bit_reset () function uses both the bitwise ^ (exclusive or) and & (and) operators. These operators help to isolate the individual bit and set only that bit to 0. … WebC-style bit-manipulation. The value of the bit can be obtained by shifting the number to the right x times and then performing bitwise AND ( &) on it: (number >> x) & 1LL; // 1 if the 'x'th bit of 'number' is set, 0 otherwise. The right-shift operation may be implemented as either an arithmetic (signed) shift or a logical (unsigned) shift.
