WebMar 1, 2024 · If both bits in the compared position of the bit patterns are 0 or 1, the bit in the resulting bit pattern is 0, otherwise 1. In short, it means that it returns 1 only if exactly one bit is set to 1 out of the two bits in comparison ( Exclusive OR ). A = 5 = 0101, B = 3 = 0011. A ^ B = 0101 ^ 0011 = 0110 = 6. That was the basic stuff about XOR.

For example: 0011 ^ 0101 = 0110 since 0 ^ 0 = 0 0 ^ 1 = 1 1 ^ 0 = 1 1 ^ 1 = 0 Because of this, we can apply XOR to anything, not just booleans.
