WebYou may assume that lowbit and highbit are both greater than or equal to 0 and less than or equal to 31. If lowbit > highbit, then the returned mask should be all zero. For … WebThe usual way is to take a 1, and shift it left n bits. That will give you something like: 00100000.Then subtract one from that, which will clear the bit that's set, and set all the less significant bits, so in this case we'd get: 00011111. A mask is normally used with bitwise operations, especially and.You'd use the mask above to get the 5 least significant bits by … Web* bitMask - Generate a mask consisting of all 1's * lowbit and highbit * Examples: bitMask(5,3) = 0x38 * Assume 0 <= lowbit <= 31, and 0 <= highbit <= 31 * If lowbit > highbit, then mask should be all 0's * Legal ops: ! ~ & ^ + << >> * Max ops: 16 * Rating: 3 */ int bitMask(int highbit, int lowbit) {//Make a mask for the end granthams printers

WebJul 22, 2015 · Bit masking allows you to use operations that work on bit-level. Editing particular bits in a byte (s) Checking if particular bit values are present or not. You actually apply a mask to a value, where in our case the value is our state 00000101 and the mask is again a binary number, which indicates the bits of interest.
