or operator (^) Bitwise exclusive or operation calculates the bitwise of the two calculation components according to the following rules: 0 ^ 0 = 0, 0 ^ 1 = 1, 1 ^ 0 = 1, 1 ^ 1 = 0 That is, if the values of the corresponding bits are the same, the result is 0. If the values are different, the result is 1. For example, the result of 013 ^ 035 is 026. The XOR operation is used to determine whether the bitwise values of the two computation components ar
