As I understand it, Unix terminal IO is buffered, so nothing will
be written until a newline is sent. You never sent one, so all
bets are off; the standards don't guarantee anything if you don't
send at least one new line. (Similarly by default even character
by character input won't see anything until the user presses return).

Try

#include <iostream.h>

main()
{
    cout << "Hello there." << endl;
}

You would theoretically get no output from

#include <stdio.h>

main()
{
    printf("Hello there.");
}

either. I haven't checked though.
