Notes for Slide 07
The answers to these questions might require some thinking.
Since the if-statement has a condition in it, we know that
a not-operator could exist in an if-statement.
Since a not-operator will turn a true into a false, and a
false into a true, using two not-operators is the same
as not using any not-operators. The final question might
depend on your personal preference, but most people prefer
to use an else-statement instead of negating the first of
two if-conditions with a not-operator.
