Honestly I like K&R, maybe more for the historicity of it than the learning but it’s good for that too. It also has some intentionally funny bits wedged in there if you read closely enough 😀

I liked this C book I read during lockdown { also its free and I did not want to spend a lot ! }

"Effective C" by

@SasLuca
has an excellent presentation on modern C on YouTube.

For those who learn best by reading a reference, after learning a few basics : Harbison/Steele

Per Vognsen’s bitwise series showed me how c should be written
