When to use "function pointer" and "function pointer"?

What is a "function pointer"? What is a "function pointer"?

I have not been able to find out what the difference really is between them.

What's pFunc

in the code below?

int(*pFunc)(int, int) = Add;
int i = pfunc(5,3);
....
int Add(int x, int y) { return x+y;}
