Print Adult Or Not
Geoffrey Challen // 2021.8.0
In the United States, you are legally an adult once you turn 18 years old.
Given an already-declared Int variable age containing a person's age, print "Adult" if they are legally an adult
and "Not Adult" if they are not.
However, if an already-declared Boolean variable whisper is true, then don't print anything at all.
Do not modify age or whisper.
