I understand and completely accept that you find the while loop
clearer, and I have no interest in changing your mind.

I find the for loop clearer.  I won't speak for anyone else, but I
suspect a lot of C programmers would also find the for loop clearer.

I don't believe you've ever acknowledged that.
