WebRotate bits, addressed by the bit. That is, say: "rotate bits 13-17, wrapping around the edges," or, "rotate bits 13-17, lose bits on the one side, set all new bits to 0." Similarly, revert regions of bits, apply logic to regions of bits, … WebBy default, bitset flips bits to on or 1. You can optionally use the third input argument to specify the bit value. bitset does not change multiple bits at once, so you need to use a for loop to change multiple bits. Therefore, the bits you change can be either consecutive or nonconsecutive.
