In C++ it does, because they are different function calls.

If they are overloaded.

Do C++ assumes that i++ and ++i same for overloaded operators?

edit: same if they are same in the case of primitives

It cannot assume that, specially in binary libraries.

You separate overloads need to be provided and the compiler cannot know if the behavior is the same.

I always use the same approach as in pure OOP languages and FP ones, assume everything is a method call.
