Notes for Slide 15
A few more rules about the elseif-statements is that
you do not need to use them if you do not want to,
as seen in the previous lessons. If you do use
elseif-statements they must be located between an
if-statement and an endif-statement (it is common to
say that the elseif-statement "belongs to" that
particular if-statement), and they must appear
before the else-statement that belongs to that if-statement
(if there is an else-statement).
