"C in a Nutshell 2nd Ed" (O'Reilly, Prinz & Craqford, 2015) is a good reference although maybe not the best for a walk-through learning experience. It also has good chapters on tooling (gcc, make, gdb). There's a recent book out I came across called "Bare Metal C" (No Starch Press, Oualline, 2022) which unpacks embedded programming in a very readable manner. I imagine a lot of, if not most, C programming these days is done in the low-level embedded world, and this book clears up a lot of the mysteries. https://nostarch.com/bare-metal-c https://nostarch.com/bare-metal-c Also it never hurts to look at a good open-source codebase written in C, for example the SQLite code is worth looking at (if a bit overwhelming): https://github.com/sqlite/sqlite/tree/master/src https://github.com/sqlite/sqlite/tree/master/src
