Which operator delete?

Question

Is there a difference between:

operator delete(some_pointer);

and

delete some_pointer;

and if so what is

Answer 1

delete some_pointer; is the "correct" one to use.

operator delete(some_Pointer); exist mainly as an artifact of the syntax for defining you own delete operator. That is, because you define an plus operator as;

 myclass::operator+(myclass b) {....}

you really could write:

 myclass c = a.operator+(b);

but no one ever does that. They use:

 myclass c = a + b;

Similarly, you could write operator delete(some_Pointer);, but no one ever does.
