Answer 1

Because you printed num, not num + 2. By The way, you didn't use the break keyword, so that might mess it up

Answer 2

You didn't assign a new value to num.

Try switch(num+=2)

Answer 3

Airree if the tested numbers are 1,2, or 3, thats where having no break will mess it up 😀. That is, unless default is set before your cases
