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)
