Now we want to combine these into one variable. The operator works by looking at each bit, and returning 1 if the bit is 1 in either of the inputs. So: 0011 0101 = 0111. If a bit is 0 in one input, then you get the bit from the other input.

WebThe unary bitwise complement operator " ~ " inverts a bit pattern; it can be applied to any of the integral types, making every "0" a "1" and every "1" a "0".
