What does the following statement mean? int(*fp)(char*)

Question

I got this question in a challenge and I dont understand

int (*fp)(char*);

The 4 possibility to answer were:

1. function taking a char* argument and returning a pointer to int

2. Pointer to a pointer

3. Pointer to an array of chars

4. pointer to function taking a char* argument and returns an int

So when I use this code

cout<<*fp;

I get 1

So ... after some thinking I think its either 1 or 4, but I dont know it exactly, so I'm writing this question.
I need/want to know what int (*fp)(char*) means
and also wich one of the questions is right

Answer 1

A pointer to function fp that accepts a pointer to char (open sized string) and returns an integer value. 4th one is correct.

Answer 2

scanf("%d4s", str)
