x=x+1 vs. x +=1

Question

I\'m under the impression that these two commands result in the same end, namely incrementing X by 1 but that the latter is probably more efficient.

If this is not c

Answer 1

In C++ it depends what datatype is x and how are operators defined. If x is an instance of some class you can get completely different results.

Or maybe you should fix the question and specify that x is an integer or whatever.
