I think you were supposed to use the stl copy algorithm:

#include <iterator>
using namespace std;
copy(istream_iterator<string>(cin), istream_iterator<string>(), ostream_iterator<string>(cout, "\n"));

The relevant stl doc is http://www.sgi.com/tech/stl/copy.html

I think you're looking for this.

using namespace std;

cout<<"Enter something: ";
cin>>inputvar;

Start with

putchar(getchar());

then work from there.
