The bitwise ^ operator performs a bitwise exclusive OR operation.

Applied, this does:

false ^ false = false
false ^ true = true
true ^ false = true
true ^ true = false

When it comes to integer varibles (including the type char) the numbers are converted to their binary representation and then the operator takes place. For example:

3 ^ 5 = 011 ^ 101 = 110 = 6
