* <code>put_string</code> outputs a string, passed as argument, here <code>"Hello World"</code>.
* <code>put_new_line</code> terminates the line.

Rather than using a call to <code>put_new_line</code>, the first version of the class simply includes a new-line character, denoted as <code>%N</code> (the percent sign is used to introduce codes for [[Eiffel language syntax#Special characters|special characters]]), at the end of the string.
