im gonna start learning The C Programming Language just so i can make the infamous scratch game Appel and port it to homebrewed systems i have
also i still havent touched that c++ book
i would learn rust, however i have to go with C mainly because the sdks i need for platforms i want to develop for (for instance vitasdk for the playstation vita) is, well, for C (and i guess to an extent C++)
i use the rust crates for those platforms
