>>>Jim,
>>>As many already said you can do that, however you're right to a point, should you do that:) I tend not to create recursive functions if I can create one that's not recursive (and almost all the time I find a non-recursive one). IMHO recursive code is easier to write but is evil. With recursion you should be very carefull not to overflow stack space and/or nesting levels.

I believe that's what my C++ teacher told us while ago. He gave us some problems to try to write non-recursive solution. I don't remember right now, if I was able to crack them.

In several cases the non-recursive solution is very hard to invent.
