In this homework assignment you have
the opportunity to experiment with boolean expressions and conditional
statements.
Before you Begin Coding
It's easy for the logic in this assignment to get out of control very
quickly. We strongly recommend that you sit down with a pencil and
paper to sketch the flow of the logic that you'll need. Use pseudocode,
rough flowcharts, boxes, arrows, stickmen, or whatever means you need
to create a clear structure for the logic of your Rock, Paper, Scissors
game.
After you have pseudocode for your solution, then create
yourself an empty project. You should know how to do this by now.
RPS
Most of you have likely played the classic game Rock, Paper,
Scissors. Believe it or not, a hardcore world of Rock, Paper,
Scissors has existed, even in Denver.
It's a bit frightening.... So, before you start thinking how Rock,
Papers, Scissors (or RPS for those in the know) is a kid's
game, think again. This is serious stuff; go ahead and TRY to beat the
computer on this NY
Times link. (But, if anyone asks, your C++ homework this week is
to implement a simple interactive rule-based system that addresses a
theoretical Decision Problem.)
Instructions: Step I
Your goal is to implement a two-player version of Rock, Paper,
Scissors. Players will enter either R or r
for rock, P or p for paper, and S
or s for scissors. Your program must then simply
announce the winner. Note that your program only needs to play one
round of the game. We will add repetition via loops soon. Here is an
example interaction:
Welcome one and all to a round of Rock, Paper Scissors! (Enter P, R or
S)
Player one: R Player two: s Rock beats scissors. Player one wins! Here is another example:
Welcome one and all to a round of Rock, Paper Scissors! (Enter P, R or
S)
Player one: p Player two: S Scissors beats paper. Player two wins! Your program must only prompt for two
inputs. It should also print a line following this pattern:
X beats Y. Player Z wins!
Where X and Y are one of "rock" or
"scissors" or "paper" and Z is either "one" or "two".
Yes, we (and the RPS
Society) understand that this interactive game is a little silly
since Player two can always see what Player one chooses. Let's fix this
issue next (AFTER you have this silly initial game working).
Instructions: Step II
Now that you have your RPS game working correctly, modify your code to
let the computer generate a random number for Player 2. Specifically,
generate a random number and then use
(randNumGenerated % 3)
to generate a 0 (rock), 1 (paper), or 2 (scissors) for Player 2. (Then
assign 'r', 'p', or 's' to Player 2's choice accordingly.)
Example outputs follows:
Welcome one and all to a round of Rock, Paper Scissors! (Enter P, R or
S)
Player one: R Computer: s Rock beats Scissors. Player one wins! Here is another example:
Welcome one and all to a round of Rock, Paper Scissors! (Enter P, R or
S)
Player one: R Computer: p Paper beats rock. Computer wins! The solution you submit should provide
output like the last two example outputs.
Grading Rubric
Your submission will be graded according to the following rubric.
Submission
Always, always, ALWAYS update the
header comments at the top of your main.cpp file. And if you ever get
stuck, remember that there is LOTS of help
available.
In summary, for homework due on
Wednesday, September 07 follow these specific steps:
