Working with Variables and Condionals
Introducon
Design is very important when developing programs and there are a variety of ways to approach it. You may
draw pictures, write it out in prose or structured text, use pseudo code, and more! The point of design is to
give you a blueprint to follow while you are coding. This saves time debugging your program as you can
catch mistakes early. It is better to spend one hour of designing than it is to spend five hours debugging.
For this assignment you must design a solution to the following problem statement and implement your
solution.

(hps://web.engr.oregonstate.edu/~goinsj/resources/CS161/Polya_template.pdf)
General Grading Breakdown:
Understanding the problem. (Recognizing what is asked.) (5 pts)
Devising a plan. (Responding to what is asked.) (10 pts)
Carrying out the plan. (Developing the result of the response.) (75 pts)
Test Plan/Looking back. (Checking. What does the result tell me? ) (10 pts)
Problem Statement
The local middle school would like some text adventure games to keep their students occupied during down
time. The school is leaving it up to your skill and good judgement to develop a game. It is up to you what the
story and theme is but there are some requirements:
There must be at least five different "if" statements involved in the adventure
At least one of those "if" statements must contain a nested "if" statement
There must be an element of chance that would change a user’s chosen path
You must handle invalid input from the user.
An example run of the program could look as follows:
Hello and welcome to the Wilderness Adventure Game!
To go right enter 1, to go left enter 2: 1
You chose to go right. You have now entered the grasslands and are being followed by oxen. They look friendly.

https://oregonstate.instructure.com/courses/1698697/assignments/7388746 2/5
Enter 1 to befriend the oxen, enter 2 to run from the oxen: 1
You attempted to befriend the oxen. You think you can ride one of them.
Enter 1 to attempt to ride the ox, enter 2 to walk away: 11
Oops! That wasn’t a valid response. Please try again: 1
Unfortunately fate was not on your side. [due to a random number within C++]
You were thrown from the ox’s back and are forced to walk away.
Enter 1 to walk right, enter 2 to walk left: 1
You chose to go right. You have now entered the swamplands and have spotted an approaching alligator. Enter 1 to h
ide, enter 2 to run home: 2
You chose to go home. The adventure has ended.
The rest of the implementation is up to you, but try to make your game as clean and attractive to play as
possible.
(25 pts) Design Documentaon
You should create a written document that addresses the points listed below. Please see the example
design template (https://web.engr.oregonstate.edu/~goinsj/resources/CS161/Polya_template.pdf) .
Understanding the Problem (5 pts)
What is the problem asking you to do? What are the inputs for the problem? What questions do you have
about the problem?
Devising a Plan (10 pts)
What is the theme of the adventure going to be?
What are the options?
List the decisions you will give in your text adventure?
Which decisions will have an element of chance?
How are you going to create the element of chance?
How are you going to handle invalid input entered by the user?
Test Plan (10 pts)
You need to consider good and bad values for your program. Remember to include tests for less obvious
invalid inputs such as the word "one".
Input Value(s): Expected Outcome: Actual Outcome:

(65 pts) Implementaon
In addition to the design process, you must implement your program as a C++ program. Here are
implementation requirements:
There must be an empty line separating each navigation option (e.g. your program should not simply
generate a "wall-of-text").
The choice system must be based on numbers. Non-numeric input is not allowed in this program.
You must gracefully handle invalid input from the user that is not one of the allowed choices. Clarification
(10/6/18): The TAs will only test your code with numeric input (e.g. -125, 1, 2, 0, 1253, etc).
You must use if/else statements and/or switch statements.
You need to use the rand() function to add an element of chance.
You must have at least 5 different paths/solutions that can be followed to complete the game.
Clarification (10/6/18): As noted in class, for this assignment you simply need at least 5 "if"
statements within the game portion of your code. In addition, at least one of those 5 "if"
statements must have a nested "if". It is also acceptable to use "switch" statements in place of
the "if" statements.
Notice that these requirements leave lots of room for creativity! Try to create an interesting game that you
think people would enjoy playing.
(10 pts) Extra Credit
Continue to ask the user if they want to play the adventure game again and repeat until the user decides not
to play anymore.
(10 pts) Program Style/Comments
In your implementation, make sure that you include a program header in your program, in addition to proper
indentation/spacing and other comments! Below is an example header to include. Make sure you review the
style guidelines for this class
(https://web.engr.oregonstate.edu/~goinsj/resources/general/cpp_style_guideline.pdf) , and begin trying to
follow them, i.e. don’t align everything on the left or put everything on one line!

Reminder
Every assignment in this course is graded by demoing your work for 10 minutes with a TA. You are required
to meet with a TA within two weeks of the due date to demo. You can schedule a demo with a TA from the
TA Office Hours tab in Canvas. The available times can be viewed in the far right column of the table
(labeled "Grading Hours"). Click on one of the links to access the poll and insert your name in a specific time
slot.
Demo Outside 2 Weeks: Assignments that are not demo'd within the acceptable time period will be
subject to a 50 point deduction.
Demo Late Assignments: Late assignments must still be demoed within the two week demo period
beginning from the assignment's original due date.
Missing a Demo: If you miss your demo with a TA, you will receive a 10 point (one letter grade)
deduction to that assignment for each demo missed.
Each program needs to be written according to the style guidelines
(https://web.engr.oregonstate.edu/~goinsj/resources/general/cpp_style_guideline.pdf) for this class. Remember
that an important part of computer programming is making sure that your work is easily understandable by
other programmers.
Electronically submit your C++ source code and your design documents by the assignment due date, using
TEACH (https://engineering.oregonstate.edu/teach) . You may use one of the document scanners (available
in KEC1130 and some other College of Engineering labs) to scan your paper design into a PDF document
that can be submitted to TEACH (https://engineering.oregonstate.edu/teach) . Your submission will have two
files: a .cpp file and a .pdf file containing your design paperwork.
