Do you have specific things that are a problem? Like "How do I ____"?
Normally in programming you can search like "C, active directory, get active users" and you'll get code for how to get just that--same for all languages where it's possible. Not sure how advanced your questions are though
Normally though you get links to the same sites all the time, so you could just search for something simple, and click a link, even if you had a "C hello world" and searched for that---you get code examples! One of them seems to be an online C teaching class even.
