 We haven't nearly covered the whole of C, but you should have pretty solid basics now. Now you just have to go and write a lot of C programs, that's the only way to truly master C. WARNING: Do not start with an ambitious project such as a 3D game. You won't make it and you'll get demotivated. Start very simple (a Tetris clone perhaps?). Try to develop some consistent programming style/formatting -- see our [LRS programming style](programming_style.md) you may adopt (it's better than trying to make your own really).

 You should definitely learn about common [data structures](data_strucutre.md) ([linked lists](linked_list.md), [binary trees](binary_tree.md), [hash tables](hash.md), ...) and [algorithms](algorithm.md) ([sorting](sorting.md), [searching](search.md), ...). As an advanced programmer you should definitely know a bit about [memory management](memory_management.md). Also take a look at basic [licensing](license.md). Another thing to learn is some [version control system](vcs.md), preferably [git](git.md), because this is how we manage bigger programs and how we collaborate on them. To start making graphical programs you should get familiar with some library such as [SDL](sdl.md).
 
 A great amount of experience can be gained by contributing to some existing project, collaboration really boosts your skill and knowledge of the language. This should only be done when you're at least intermediate. Firstly look up a nice project on some git hosting site, then take a look at the bug tracker and pick a bug or feature that's easy to fix or implement (low hanging fruit).
