I'd like to know if it's possible to create and array of function names. For
instance, let's say that a menu has 5 options; if I could just detect what is the
chosen option (let's say, n), I could use the stored function name at the position
n, instead of a long switch. Or maybe, a more clever approach to solve this menu
problem... Actually, I have the same problem with the mouse. 
What's the best way to tell the program: 'If you click here, do it', or 'If you
choose this option, do that'??? To handle the mouse hot-spots, I thought about
creating a struct like:
struct mousespot {
    char minx, maxx, miny, maxy;
   ?function? // problem here
}
and check: if ( cursor < maxx && cursor > minx &&  cursor < maxy && cursor > miny
), but how to handle the function? Would a pointer to a function work? How to
declare it?
