Bit masking interview questions
Webflags = 1; To clear the bits of interest, the number is bitwise ANDed with the one's complement of the bit mask. The "one's complement" of a number is the number with all its one bits changed to zeros and all its zero bits changed to ones. The one's complement operator in C is ~. For instance, you could clear the one's digit of flags like so: WebTo set a specific bit to 1, you can use the OR operator. First, the bit you wish to set is shifted to the position you wish to set it to, the OR operator does the rest. byte = 0b0000 byte (0b1 << 2) = 0100. To set a specific bit to 0, you must use the AND operator. byte = 0b1111 byte & (0b0 << 2) = 1011.
