The use of the xor operator ^ in C++

The ^ operation in C++ represents a binary xor operation
2 ^ 4 = 6
010 ^ 100 = 110

This operation can be used to convert two Numbers without intermediate variables

The following example implements the substitution of a and b

A = 2;

B = 4;

A = a ^ b;

B = a ^ b;

A = a ^ b;

  Xor ^ is a very important operator, and a large number of problems can be solved by using xor, especially in the interview questions of major companies. Xor is definitely a key operator.
