RE: Problems with stringstream

["Moore, Mathew L" <MooreML@BATTELLE.ORG>]

std::endl will flush the buffer (after adding a new line).  If you don't
want to add the newline then you can just flush() it:

  cout << mystr;
  cout.flush();

Do you need to add the extra strings as well, or does just the flush() work
for you?

I thought that the streams were automatically flushed when they reached the
end of their scope (at the end of your main function here).  Anybody know if
that is incorrect?
