do not paraphrase code in comments.

you probably want to make this a const

useless comments are a pain.

why require so many words for something so simple?

How much commenting will you resort to the really complicated stuff?

wrong assumption, but irrelevant.

Simple concepts are more effectively conveyed thru standard symbols*.
Fast english readers do not spell out words, or pronounce them in their heads.
Fast code readers do not like to have to read a lot of english, because in C
punctuation conveys more meaning than words.

while (!done) looks a lot like while(done) or while (idone)

for (;;) is blatantly unambiguous.

Chqrlie.

*: this is a requirement in multicultural areas, road signs are a good example:
they are not used so much in the US, where everything is written, sometimes even
abbreviated beyond repair (what is a PED XING? where is B'WY/NY?)
