Granted but a decent compiler can easily inspect the above 'for' loop and 
replace it with the preceading while 'loop' equivalent. Going the other 
way would be MUCH harder. So there is an advantage to having a 'for' loop 
construct in addition to a 'while' loop construct.

There is no excuse for a compiler that generates inferior code in this 
case.

But I ask again specifically why does Chuck Hellebuyuk depricate 'C' 'for' 
loops?
