Notes for Slide 09
The answers to these questions should all be clear from
reading the slides or from reading these notes. A program
without input would run the exact same every time, which would
not be very interesting. Most programs have some sort of input.
Besides the keyboard, input could come from a mouse or a
microphone or various other input devices. When a program is
running, it will continue to wait for input when it sees a
JJS.input statement. It will conceivably wait forever or until
the person running the program enters input.
