- Introductory C programming so far, maybe it will get faster/more interesting later on.
I wouldn't recommended videos I've seen so far to anyone familiar with C.
I'm not a big fan of video tutorials, one could read the code or write it himself in half the time. I consider it a lazy form of sharing knowledge, as opposed to written text or real, interactive lecture. Ofc there are exceptions like cooking or make-up guides, but programming is not one of them :P
