Logical XOR operator in C++?

Question

Is there such a thing? It is the first time I encountered a practical need for it, but I don\'t see one listed in Stroustrup. I intend to write:

// Detect wh         


        

Answer 1

The XOR operator cannot be short circuited; i.e. you cannot predict the result of an XOR expression just by evaluating its left hand operand. Thus, there's no reason to provide a ^^ version.
