WebMar 15, 2024 · XOR is a logical operator that works on bits. Let’s denote it by ^ . If the two bits it takes as input are the same, the result is 0, otherwise it is 1 . This implements an exclusive or operation, i.e. exactly one argument has to be 1 for the final result to be 1 . We can show this using a truth table: x. y. x ^ y. 0. Web1 day ago · When programming, we often need constant variables that are used within a single function. For example, you may want to look up characters from a table.
