Assignment: Programming Assignment 8

Description:

This program is for a "price is right" game. Where there
are four players who are all competing again each other
to guess the closest without going over on a set item price
for a total of three rounds. The winner of each round has an increasing
payout while a consolation price is still paid for zero wins.

The guesses are input by the user and then the program calculates
if all the players are over and it will repeat the round or it
will find theplayer who is closest to the exact price. Upon this
that play is given a round winand it continues like this for 3 rounds.

The output will be a list of all players, their rounds won,
and the total winningsin dollars calculated as well.
