Hello everyone !

First of all I hope my english will be understandable, but if not - please tell me about this.

I would like to ask you for help. I need many practical resources about C programming. Short story about me - I love C language and linux os and I have strong theoretical knowledge about C language (it's opinion from company where I applied without success), structures, pointers etc, but I have a problem with implementing solutions like linked lists, stack and others.

I search Internet for any problems to solve, structures implemented in C and others. Do you know any good resources that programmer can improve his practical skills ? I also look for any idea to build big program in C which, I don't know, requires multitasking ? I will be very grateful if you will provide me any links, titles of books where are practical problems to be implemented in C. I'm not looking for theoretical links and tutorials.

Greetings.
Martin
