Problems with stringstream

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?
