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.

It's cute that you think condescension matters with regards to the subject at hand, and that your post is at all relevant and not just to make yourself feel better. Meanwhile, ``meanwhile'' isn't really a contrast to ``it's cute'' so it doesn't really make sense and is confusing if you're trying to make a point, and the people who actually know anything are talking.
