WebApr 10, 2024 · In C, the following 6 operators are bitwise operators (also known as bit operators as they work at the bit-level). They are used to perform bitwise operations in C.

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.

WebMar 15, 2024 · Most programming languages implement ^ as a bitwise operator, meaning XOR is individually applied to each bit in a string of bits (e.g. a byte). 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. Deducing Some Useful Properties
