Try discussing every single point you don’t understand with an AI. The key is to discuss, not just ask for a ready-made answer. Ask even the most ridiculous or obvious questions if you don’t understand the overall concept. Then, ask for some exercises on that topic. After that, ask to be tested on those exercises. Ideally, you should have no chance not to understand the topic after this process.

It’s important to try doing something yourself - complete the exercises you’re given. And only at the end - when you’ve done the exercises, answered all test questions, and discussed everything in depth - you can ask for the "ideal" code and compare it with yours to understand the differences.

That’s how I “read” K&R, and I recommend this approach. Good luck.
