// "The C Pre-Processor (CPP) is the somewhat basic macro system used by the C
// programming language to implement features such as #include and #define
// which allow very simple text-substitutions to be carried out at compile time.
// In this article we abuse the humble #define to implement if-statements and iteration.
//
// Before we begin, a disclaimer: these tricks, while perfectly valid C, should not be
// considered good development practice and should almost certainly not be used for "real work".
// That said it can totally be used for fun home-automation projects...
