A bit wise NOT (unary complement) operates on the bit level and simply flips each bit. If it's a 1, it's changed to a 0, if it's a 0, it's changed to a 1. The bit wise NOT has the same effect as XOR'ing a value against the max value for a specific type: unsigned char a = 234; // 1110 1010b (0xEA) unsigned char b = ~a; // 0001 0101b (0x15 ...
