Introduction to the use of bitwise XOR operators in C ++

The two values involved in the calculation. If the two corresponding bits are the same, the result is 0. Otherwise, the result is 1. 0 ^ 0 = 0, 1 ^ 0 = 1, 0 ^ 1 = 1, 1 ^ 1 = 0

Example: 10100001 ^ 00010001 = 10110000

0 ^ 0 = 0 0 ^ 1 = 1 0 variance or any number = any number

1 ^ 0 = ^ 1 = 0 1 variance or any number-returns the inverse of any number

Set yourself to 0 for any number difference or yourself =

(1)Bitwise exclusive or can be used to flip certain specific bits, such as the 10100001 and 2nd bits of the logarithm 3rd, and bitwise exclusive or operation can be performed on the number and 00000110.

10100001 ^ 00000110 = 10100111 // 1010 0001 ^ 0x06 = 1010 0001 ^ 6

(2)By bitwise XOR, two values can be exchanged without using temporary variables. For example, you can use the following statement to exchange the values of two integers, a and B:

A = 10100001, B = 00000110

A = a ^ B; // a = 10100111

B = B ^ a; // B = 10100001

A = a ^ B; // a = 00000110

(3)The unique or operator is characterized by the fact that the number a is two different or the same number B (a = a ^ B) is still the original value.
