Yes, you should be able to.

You don't "do" a function pointer. You can declare it, like this:

void (*functionpointer)(int, double);

'functionpointer' is a pointer to a function that takes two arguments
and returns nothing.

Pointers to non-static member functions are not compatible with plain
pointers to functions. What book on C++ are you reading that does not
explain those concepts?
