The bitwise complement operator, the tilde, ~, flips every bit. A useful way to remember this is that the tilde is sometimes called a twiddle, and the bitwise complement twiddles every bit: if you have a 1, it's a 0, and if you have a 0, it's a 1. 0, of course, is all 0s: 00000000 00000000.
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 nth bit of number into the variable bit. Changing the nth bit to x. Setting the nth bit to either 1 or 0 can be achieved with the following on a 2's complement C++ implementation: number ^= (-x ^ number) & (1UL << n); WebBitwise right shift in C++ programming language is used as follows: >>.
