This talk was actually meant for beginners and for those who were acquainted with C to some extent. Furthermore, many never learn about the preprocessor features (at least here in India) and I ended up explaining things in detail which made up a majority of the post. I know it feels as if there was a prime focus on the preprocessor, but that wasn't the idea. It just took longer to explain those features (at least for beginners).
