This is modestly silly :) C is still a *high level language*,
and there's very little you cannot do with it.

I have personally replaced a really large pile 'o Java
with a relatively small 'C' program. That wasn't
Java's fault.

Don't say "Buh GUI programming..." I'll agree there;
don't use C for that. Or just don't write GUIs.

Type conversions must be made explicit.

That's a way. I do it the other way 'round, but
that's fine. Having the "unsigned" keyword be the exception
adds more information to the source code and otherwise constraining*
signed ints is better than simply declaring everything unsigned.

Well, there ya go.
