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

For a true logical XOR operation, this will work:

if(!A != !B) {
    // code here
}

Note the ! are there to convert the values to booleans and negate them, so that two unequal positive integers (each a true) would evaluate to false.
