Iteration in C

Hi there /prog/.

I know Python, and I'm learning C. Both langs have for loops. Python's nicely iterates over a collection of unknown length. C's usually has you specify the length of the collection at compile time, but what if the length is unknown?

My best newbie guess: you terminate the collection with NULL, or you write an iteration function that returns some end-of-collection value when it's done.

You're really bad at reading comprehension, aren't you?

Because he's an idiot, and when other people are discussing arrays of ints, he expects people to read his mind and follow his train of thought when he butts in and starts attacking the straw man of char arrays (without clarifying that that's what he's doing, of course).
