Second, I don't think you've made your question any clearer. I think
the problem is that you're asking the wrong question. Somebody
mentioned pointers; it's true that pointers play a larger role in C
than in most other languages. But I think what you really need is
advice on how to learn C.
K&R2 (Kernighan & Ritchie's "The C Programming Language", 2nd Edition)
is almost universally considered to be one of the best C tutorials in
existence. Get a copy of the book and work through it. Do the
exercises.
Read the C FAQ, <
http://www.eskimo.com/~scs/C-faq/faq.html>. Parts of
it may not make much sense yet, but they should by the time you finish
K&R2. The FAQ also has some advice on books and other resources.
Pick a good medium-sized project and implement it in C. I don't have
any good ideas off the top of my head, but I'm sure others will.
