WebAug 2, 2024 · The bitwise exclusive OR operator ( ^) compares each bit of its first operand to the corresponding bit of its second operand. If the bit in one of the operands is 0 and the bit in the other operand is 1, the corresponding result bit is set to 1. Otherwise, the corresponding result bit is set to 0. Both operands to the operator must have ... WebThe bitwise AND operator is a single ampersand: &. A handy mnemonic is that the small version of the boolean AND, &&, works on smaller pieces (bits instead of bytes, chars, integers, etc). In essence, a binary AND simply takes the logical AND of the bits in each position of a number in binary form. dick\u0027s holiday hours
