In the embedded world where there are a lot of C compilers, it's not so much the language you keep in your head but the compiler implementation of the language.

I'm in the process of moving an old codebase from a compiler with a very loose adherence to an old specification to an ARM chip that is using GCC for the compiler. Enabling -Wall to catch all issues that the compiler highlighted, 16-bit ints to 32-bit ints, and quite a few ternary operator issues.

None of these were issues on a system that's been running in production for many years but porting to a new architecture will mean there’s a lot of extra testing to be done just to make sure we catch all the edge cases in the code.

I like the C language and have been using it for close to 30 years now. The main part of the language can be kept in your head but there is so much more to working with it than just the base language.
