The C programming language: its historical aspects and use on/targetting retro platforms.
This tag is for questions about the history of the C language and its use on retrocomputers, including C compilers targeting retro platforms.
C programming questions are on-topic only so far as they are specific to a retro platform, such as when asking about platform-specific compiler extensions. General questions about C programming (i.e. those that could apply to modern platforms as well) should be instead asked on Stack Overflow. In particular, this tag is not for versions of C (such as C99) that are not being compiled for retrocomputers (such as code produced by Visual Studio 2013), despite the age of the standard.
