Question

Here is what I’ve copied from MSDN about new operator:

The new operator cannot be used to allocate a function, but it can be
used to allocate pointers to functions. The following example
allocates and then frees an array of seven pointers to functions that
return integers.

int (**p) () = new (int (*[7]) ());
delete *p;

Well there is nothing strange with first line, it allocates an array of pointers to functions, but I just don’t understand how the second deletes that array? I think it should be:

delete[] *p;

Can anyone explain this?

Answer 1

Frankly speaking the right answer was written in the avakar’s comment.
The right code is

delete[] p;

delete *p; is incorrect for two reasons:

1. we must use delete[] for all dynamically allocated arrays. Using
   delete will cause an undefined behaviour.
2. pointers to static and member functions cannot be deleted
