Thanks! I also read about the 'red and blue' book. Would you recommend those or are those outdated?
You can read the
red and the
blue book online.
I don't think there's such a thing as "outdated" because it's fundamental to understand how things worked in the past and why they changed.
I wouldn't really recommend to have them in the shelf, though. Once you've picked up the basics they're pretty useless.
I don't have an ide, i just use vi 
Do you recommend an ide?
On linux I use .pro-files and qmake (which belongs to qt and ships with kde) which is somewhat more convenient than the standard makefiles.
An IDE is essential to organize your project, refactor your code and run the debugger.
My favourite is
qt creator. It's targeted at developing qt applications but also works without it.
Of course there are some others, too (eg eclipse/cdt, code blocks) but they'll make your life only half as wonderful
