When a function pointer is declared, a signature of the function that
the pointer may point two is specified. For example

    int (*fp)(int, string); 

Specifies that fp may point to functions that return int and take two
parameters: integer and a string, both by value.

Like any pointer, a function pointer may be assigned a value: the
address of a function. A function name is a constant function
pointer. So the assignment may happen like this:

    fp = myfunc;

It may happen at declaration:

    int (*fp)(int, string) = myfunc;

The signature of myfunc should be the same as fp.

After fp points to a function it may be invoked as a regular
function. For example:
 

    int i;
    i = fp(55, "hello");
