Convert CPP to C

QUICK ANSWER
Is it possible to convert CPP to C?
Yes - CPP converts to C.

Renaming .cpp to .c forces C-mode compilation, but C++-specific code (classes, templates, namespaces, std::) won't compile as C - you'd have to rewrite it. This is a language port done by hand, not a file conversion.
