Answer 1

yeah true

Answer 2

cin gets user input.
cout returns something to the screen as output.
You don't have a cout command so nothing is returned,therefore no output.

Answer 3

num is read 5 times. nothing is done with the read input. What output are you looking for? there is no output statement.
