When you program in 'C' you are inherently giving up some direct control of memory management to the compiler (or linker, more precisely). You trust that the 'C' compiler will take care of these things for you. While I'm sure there is a way to reset internal RAM and registers in C, I would also assume that it depends on what compiler you are using.

I'd also wonder why you would want to do this in 'C'--it seems to me that, most probably, clearing internal RAM and registers in 'C' would cause problems since you'd be changing memory registers that the C compiler is probably assuming are under its exclusive control (?).
