After having coded in ASM assembler and in Z80 assembler (see this post), now I also have found a C compiler. As far as I can tell, it adheres to K&R (Kernighan & Ritchie) rather well.
I found it here.
Like assembler, this was a trip down memory lane for me. Have to re-learn a lot of syntax, pointer stuff, etc. FUN!
This is a rather challenging endeavor, not having coded C in a long while…
