WebWhy. 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 ... WebOct 25, 2013 · 4 Answers. Sorted by: 16. The &= and the ++ together are the same as X = (X + 1) % 1024; but can be computed faster by the CPU. 1024-1 is 11 1111 1111 in binary, so for numbers where X < 1024, a bitwise AND will have no effect (since any bit & 1 = the same bit). Interesting things only start to happen where X ≥ 1024, so let's consider the ...
