My favorite C programming book was Expert C Programming by Peter van der Linden, mainly for the method of reading any C declaration and for teaching me the difference between libc calls vs syscalls. There's also a book called Modern C by Jens Gustedt from 2020 that I have and is more beginner friendly.

The way I learned C is I printed out the Beej's guide client/server code and walked around staring at it until it made sense. (That and compiling/running it and looking up functions in the man pages.)
