I have a fundamental knowledge of C and I am wanting to get better at understanding C. here is an example of what I’m looking for. I write random programs to try and challenge my self with help from the man pages, for example i’m trying to create my own Linux shell right now, but I feel as i’m just using functions and not understanding what’s happening when I use them, the article that I linked helped me understand what was going on with scanf and fgets more, and I’m looking for similar articles.
It’s not as in depth as the article you posted (it’s really good btw, nice find!), but i really like Beej’s guide to C (https://beej.us/guide/bgc/html/#foreword) for an overview of the language and the tons of stuff you can do.
Just glanced over it for 10 mins, i’m probably going to look over this more, it’s bookmarked, thank you.
