What are the best resources for learning C today?

A structured interactive course such as Boot.dev could also be worth trying if you prefer guided lessons and exercises instead of learning entirely from a book. Before choosing, it may help to compare it with a few other courses and decide whether you learn better through projects, reading, or video instruction.

The classic book “The C Programming Language” by Kernighan and Ritchie is still an excellent starting point. It’s concise and somewhat dense, so you may want to pair it with a more beginner-friendly course or reference. Although it doesn’t cover every detail of the newest C standard, the core material remains highly relevant.

The age of a C book isn’t necessarily a major problem. C has changed much less than many newer languages, and most of the fundamentals in older books still apply. If you follow a book aimed at an older standard, configure your compiler accordingly—for example, with an option such as `-std=c89`—so the examples behave as intended.
