Firstly, the second 'while' loop repeats while number_of_floors > 1,
but the number of floors is never changed within that loop, so the loop
will repeat forever. Also, if there's only one floor, it won't perform
the body of the loop at all!

Secondly, you're not calculating any totals for the final section to
use.
