Description
Both
of these classes should be placed inside a package named Program2.
Program 2a: Write a program to score the
paper-rock-scissors game. Each of two
players enters either P, R,
or S.
The program then announces the winner as well as the basis for determining the
winner: “Paper
covers rock”, “Rock breaks scissors”,
“Scissors
cut paper”, or “Draw, nobody wins”.
The players must be able to enter either upper- or lower-case letters. If an
invalid choice is entered, the player should be permitted to re-enter his
choice as many times as needed. When one game finishes, the game should start
over, as many times as the player wishes to play.
Name your class program2a,
followed by your name – i.e., program2aBobSmith.
Program 2b: A population of green crud has an unusual growth pattern: it doubles its size every
five days exactly, starting from the fifth day. Hence, if a green crud
population starts out as 10 pounds of crud, then on day 5 there are 20 pounds,
on day 10 there are 40 pounds, and so on.

Write a program that
takes both the initial size of a green crud population (in pounds) and some number
of days as input, and computes from that information the size of the population
(in pounds) after the specified number of days. Note that the number of days
might not be evenly divisible by 5.
Name your class program2b,
followed by your name – i.e., program2bBobSmith.
Submitting
Work:
Submit your work as a single zip file of both
project folders on MyGCC. See Dr. Al
Moakar if you need help. Note that your program must be commented appropriately.
Be sure to submit the correct files the first time.
You will be graded on the correctness of your program and general layout of
your code (indentation etc.) according to the following scale. Remember that
you must comment this program!
A program that does not compile or
link may not be graded.
