Memory addresses of pointers

Can someone explain in plain English please...?

The question is "How would you access the memory address for a pointer: int *p ?"

I thought that &p would give the memory address of the pointer itself, *p. However that answer is wrong, the correct answer is p.

I thought that using %p and then p would give the memory address of the item that *p is pointing to, not the memory address of *p itself.

Am I understanding this backwards or is it the wording of the question that has me mixed up?

I also think the correct answer should be &p.
