Notes for Slide 03
The not-operator: ! :is called a boolean operator
because it operate on true and false values (the
boolean type is covered in the next step after
this one).
So far, the only statements we have learned that could
contain the not-operator are the if- and elseif-statements.
The slide shows that using a not-operator on the
condition in an if-statement has the same result as
using an else-part in an if-else-endif block where
the if-part is empty.
