7. /* I realize that this program is a messy
compilation of inefficient coding, and
perhaps even stands as
something blasphemous in your eyes.
Coming midterms forced me to write the
program as is because this format required
the least amount of thinking as well as the
least amount of time. Therefore, I only ask
one thing of you: Be gentle. */
