In 1982 this was fine, but now you'll probably want std::cout and
std::endl in the C++ macro. Also it would probably be better to include
<cstdio> and <cstdlib> rather than <stdio.h> and <stdlib.h> in the C++
version. If you want fstream, it should be <fstream>, but, you probably
don't actually want that. It is built on <iostream>, and you're not
using anything in <fstream>. <iostream> contains the declarations for
cout and cin.

The C looks good though. :)

HTH,
