Can you point me to some online resources?
I couldn't find any good. Also the resources shouldnt be too old.
There also wasn't any SO question covering this. Or atleast I didn't find it.
Edit: Practical approaches would be very nice too. Something like Real World Haskell but just for C. Is there something like this?
Edit2: With "too old" I mean that it should be from the 90s atleast.
Thanks
This one looks pretty good. C itself is pretty old; I'd think even 'old' resources would be fine to learn from. When you're more comfortable with the basics, you can pick up some of the changes and subtleties of the newer standards without too much trouble.
For offline resources you can't do much better than the original and best: Brian Kernighan and Dennis Ritchie's The C Programming Language.
The cprogramming.com webiste has a lot of usefull ressources such as: very active message board, tips & tricks for beginners, common sort/search algorithms, games, etc.
Also, some real (but small) projects are available in the ressource section.
K&R is certainly a fine read, but for practical nitty-gritty, one must have Harbison and Steele (C: A Reference Manual). It comprehensively covers the main variations of C that you would encounter "in the wild"-- and is also surprisingly well written for a reference book.
Online, a very good reference is the C programing FAQ. In the old days of bulletin boards, this was the FAQ for comp.lang.C, but it is still (AFAIK) meticulously maintained.
I started with The Book of C which is pretty old but a very good introduction without being too simple. It has a nice description of the standard libraries that I still use for quick reference as well.
Right now I'm reading "Expert C Programming" which has been really great at hammering down the less-intuitive parts of the language. Things like what this declaration means:
char * const *(*next[10])();
Also I think someone mentioned The C Programming Language, which is also very comprehensive.
These would suffice.
This is a pretty good resource on reddit.com:

This is the beginning of the tutorials:

I think somebody may have already mentioned it, but Cprogramming.com is the best site I've found for C and C++ related problems. The board is one of the most mature places I've encountered on the internet, and the people there are very willing to lend a hand.
