When to use "^" operator

Question

What is the operator below ^? When to use it?

My programing language is C#.

Answer 1

^ is a Logical XOR Operator if the operands are bools, otherwise it's a Bitwise XOR Operator

Binary ^ operators are predefined for the integral types and bool. For integral types, ^ computes the bitwise exclusive-OR of its operands. For bool operands, ^ computes the logical exclusive-or of its operands; that is, the result is true if and only if exactly one of its operands is true.

Answer 2

It's the XOR operator. It's used in bitwise operations, where the result is true if the left side is true or the right side is true, but false if both are true or both are false. So 0xf8 ^ 0x3f would be:

1111 1000
0011 1111
---------
1100 0111

Which is C7 in hexadecimal.

In general, if you're not doing bitwise arithmetic, you won't need to worry about it.
