You do realize that the interview was to find out if you know how to do that on your own?

Just to also clarify, I don't think they were asking for compiler code, they were asking for a parser and reformatter which would take something like:

int main(int argv,char**argv){int i;if(argv<2){printf("Usage:...\n");return -1;}i=argv[1];printf("Argument: %d\n,i);return 0;}

And reformat it so that it was spatially readable within the guidelines of a coding style document.

They're also likely looking for how you approach that problem intellectually. What's your first "take" on the problem, what questions do you have about the task you're being asked to complete, and how fast you "get" their whole point.

Yes, some interview questions are stupid, pointless, or a pet peeve of the questioner; in fact many of them are self serving. But if you claim to have mastery of the C-language, then .... they're likely going to ask you touch C-language questions. And if you claim to know it a bit, then they're likely still going to ask you C-language questions so they can see how much you do know.

If you're really interested in learning the language better, read up on references. Take this interview as a learning experience, go further and ask what they are looking for really, and do your own experimentations so that you actually learn the language by using it. Doing just "Hello World" does not mean you know C, and I'm not saying that you don't know it at all, just saying that this interviewer is trying to gage your knowledge as best as they can and they likely have several candidates. (I always thought the proper spelling was gauge, but the spell checker told me 'no')

Michael Abrash's Graphics Programming Blackbook is my favourite gfx. book of all time. It's available for free on the net.
It dates back to DOS days, so you'll probably have to find an old machine from somewhere.
