Brother
dep, your friend Carl has essentially
recreated the steps to proof by induction. This is by no
means a slam on the steps outlined, but in fact praise that
you were kind enough to share the "recipe". I think that a
lot of developers (myself included at times) forgo the
science part inherent in code development. That's why
information like this needs to be disseminated to us as a
reminder, or a slap on the face as the case may be, to help
teach good coding style. Pass the ++ on up to your friend.
ALL HAIL BRAK!!!
