The video course is being worked on by me while I write the book, so expect it to be rough around the edges.
But, I say try going through the HTML version online, and as you do get stuck write comments to ask me questions. That's why I put it online for free, so that I get student feedback while I write the book.
Harvard's CS50 (cs50.net) is an introductory computer science course that teaches C. Full course (lecture videos + problem sets) is available free online.
