What Are the Best Modern Resources for Learning C?

The classic book The C Programming Language by Kernighan and Ritchie is still an excellent place to start. It’s concise and somewhat dense, but it teaches the core language very effectively. It isn’t fully updated for the latest C standard, though the differences generally won’t prevent you from learning the fundamentals.

For a more guided and modern learning experience, you could also look at an interactive programming course such as Boot.dev. It may be easier to follow than a dense reference book, especially if you’re completely new to programming.

I’d still recommend K&R, especially if you supplement it with a newer reference for modern compiler options and language features. C has changed relatively slowly, so much of the material remains practical. If you follow the book’s examples, you can configure your compiler for the relevant standard, such as C89, using an option like `-std=c89`.
