Hello, I just need help converting this baby in plain old vanilla C.

You can tell me the equivalents of C to C++ or whatever is more convenient for you.

I'm compiling in MS Visual Studio C++ 2008 and it gives me mostly "undeclared identifiers" and "syntax errors".

Thanks in advance!

#include <ctime>

printf()....

Oh and include stdio.h instead of iostream. And time.h instead of ctime.

Also, C doesn't have references, so you'll have to convert those reference parameters to pointers.
Just out of curiosity, why do you want to convert it to C?

See here.

Thanks again.

And I answered your question on the other forum.
