WebSep 28, 2024 · The bitwise AND operator in C++ is a single ampersand, & , used between two other integer expressions. Bitwise AND operates on each bit position of the surrounding expressions independently, according to this rule: if both input bits are 1, the resulting output is 1, otherwise the output is 0. Another way of expressing this is: 1 0 & 0 == 0 WebAug 24, 2008 · Using bitwise operations for bool helps save unnecessary branch prediction logic by the processor, resulting from a 'cmp' instruction brought in by logical operations. …
