I was searching for recommendations on a good resource for learning C. The book '21st Century C' was recommended a few times on HN, and it has a good appendix on the basics, which is good for those who may not have used C except for undergrad assignments. These lectures notes cover not only the basics of the C language, but also some things that are essential to learn alongside (like how to use assert, and how to step through a program with gdb).
