The title says it all
This has probably been the most suggested addition since the sites founding, but it is sadly out of the scope of the project (which is aimed mostly at web technologies), at least from what was made clearly previously. Codecademy has developed a lot more since then, but I doubt its implementation will be any time soon, despite its clear support back then.
The commercialisation probably wont help the situation either, unless of course they start charging for new tracks entirely!
that’s the reason I joined this site!! I can’t find c language I want to prepare for my course but this site is now useless for me at this point!!!
