Any for-loop has an equivalent while-loop, and vice-versa, meaning
that there is no a "type" of loop that can be expressed in a for and
cannot be expressed in an equivalent while, or vice-versa.

Your loop above is in all equivalent to:

  for(n=r=arg0; *r; r++)
     if (*r =='/') n=r+1;
  return n;


so I don't understand your statement. Maybe I misinterpreted the
whole discussion, but really there is no difference whatsoever between
for and while, to the point that some more orthogonal languages have
only one of the two constructs.
