Agreed. It was written only as demonstration how to read
something from input file stream. I should have wrote it
with std::copy instead:

ifstream in("C:\\TEMP\\test.txt");

if(in.is_open())
{
copy(istream_iterator<string>(in),
istream_iterator<string>(),
ostream_iterator<string>(cout, "\n"));

in.close();
}
