What's the one thing you can do to most improve your C programming skills?
In my opinion, adding -Wall -Wextra -Werror to your CFLAGS, is the answer.
This flag combo turns on a lot more error checking, and turns all "warnings" into hard errors that stop the compiler in its tracks. This forces you to fix things that technically compile but shouldn't.
@mos_8502 yes, but also no because all the MCU vendor SDKs suck so badly
@mos_8502 notably, at least for GCC, `-Wall` is not all warnings. I would encourage C programmers to use `-fanalyzer` which turns on more warnings.*
