pointers to functions

[Donald E Bruey]

Is it dumb question time already this year?  Well, since someone has
to ask the first one, it may as well be me.     
 
Can some gracious .netlander please mail me some hints ( a program 
is also quite acceptable) on passing around pointers to functions?
Specifically, I've been doing a lot of numerical methods in programs
and having to call four or five functions in each program.  I don't
want to have to copy the code five times, as in




             if (count = /* value */) then do this function
        else if (count = /* another value */) then do _this_ functino
         etc

        I would rather call it like this

        subroutine ( pointer_to_function,initial_value);
        subroutine ( pointer_to_function_II, initial_value);

   and so on.  this would make my life a lot easier, but I found K&R
   a bit difficult to understand on this issue (surprise!!).  Can anyone
   help me?  Thanks in advance.

  If you do send something, mail is much more reliable than reply.
