Goals:
• To learn how to use linked data structures (Note: no array is allowed)
• To use strings
• To learn creating multiple versions via conditional compilation
• To design and implement functions
• To perform unit testing
In this homework assignment, you will write a simple trivia quiz game. You program first allows
players to create their trivia questions and answers. Multiple questions should be organized and
managed using a linked data structured; no array is allowed in this homework assignment.
Then, your program asks a question to the player, input the player’s answer, and check if the
player’s answer matches the actual answer. If so, award he player the award points for that
When all questions have been asked, display the total amount that the player has won.
Please perform the following steps to finish this assignment.
• Step 1: Create a TriviaNode structure that contains (1) information about a single trivia
question and (2) a pointer pointing to other TriviaNode. This structure must contain a
string for the question, a string for the answer to the question, an integer representing
points the question is worth, and a pointer of the TriviaNode type. Please keep in mind
that a harder question should be worth more points.
• Step 2: Create a linked list of Trivia using the TriviaNode structure defined in step 1.
• Step 3: Design and implement a function that initialize the Trivia linked list by hard-coding
the following three (3) trivia questions (including answers and award points). The
o Trivia 1:
▪ Question: How long was the shortest war on record? (Hint: how many
minutes)
▪ Award points: 100
o Trivia 2:
▪ Question: What was Bank of America’s original name? (Hint: Bank of Italy
or Bank of Germany)
▪ Award points: 50
o Trivia 3:
▪ Question: What is the best-selling video game of all time? (Hint: Call of
Duty or Wii Sports)?
2
▪ Award points: 20
• Step 4: Design and implement a function to create and add a new TriviaNode into the
linked list. You must use operator new to dynamic allocate memory to a new TriviaNode.
Please remember to check that a new TriviaNode is successfully created.
• Step 5: Design and implement a function that asks a question to the player, input the
the player the pointsfor that question. If the player enters the wrong answer your
program should display the correct answer.
o Input: a linked list of TriviaNode, the number of trivia to be asked in the list
o Output: void or int – 0 indicates success and 1 indicates failure.
• Step 6: Write a test driver to perform unit testing for the function implemented in step 5.
Assume there are three trivia in your created list, you must cover at least the following
cases: (see Fig. 1 on page 3 for the sample user interface.)
o Case 1: ask 0 question.
o Case 2: ask 1 question (i.e., the first one) from the list
o Case 3: ask 3 questions (i.e., all the questions) from the list.
o Case 4: ask 5 questions that exceed the number of available trivia in the linked list
(i.e., the index of the trivia is larger than the array size).
• Step 7: Write the main function that performs the following: (see Fig. 2 on page 4 for the
sample user interface)
o Create hard-code trivia quizzes (i.e., questions/answers/awards) (Note: just call
the function implemented in step 3).
o Create more than 1 trivia quiz from a keyboard (Note: just call the function
implemented in step 4).
o Write a for loop; in each iteration do the following:
▪ asks a question to the player,
▪ if the player’s answer matches the actual answer, then award the player
the award points for that question,
▪ else (i.e., the player enters the wrong answer) your program should display
o When all questions have been asked, display the total award points the player has
won.
• Step 8: Create two versions using conditional compilation.

o Version 1: simply run the test driver implemented in step 6.
o Version 2: a regular version run the main function implemented in step 7.
Note: this version does not include the test driver.
You must provide the following user interface for the debug version. In this version, your
program must run the test driver you build in step 6.
***This is a debugging version ***
Unit Test Case 1: Ask no question. The program should give a warning message.
Warning – the number of trivia to be asked must equal to or be larger than 1.
Case 1 Passed
Unit Test Case 2.1: Ask 1 question in the linked list. The tester enters an
Question: How long was the shortest war on record?
Case 2.1 passed
Unit Test Case 2.2: Ask 1 question in the linked list. The tester enters a
Question: How long was the shortest war on record?
Case 2.2 passed
Unit Test Case 3: Ask all the questions of the last trivia in the linked list.
Question: How long was the shortest war on record?
Question: What was Bank of America’s original name? (Hint: Bank of Italy or
Bank of Germany)?
show question here
. . .
Case 3 passed
Warning – There is only 3 trivia in the list.
Case 4 passed

You must provide the following user interface for the production version. The user input is
depicted as Bold, but you do not need to display user input in bold. Please replace “Li” with
your name. In this version, your program must run the test driver you build in step 7.

How to Create Two Versions?
You can use the preprocessor directive #ifdef to create and maintain two versions (i.e., a
debugging version and a product version) in your program. If you have the sequence
#ifdef UNIT_TESTING
#else
#endif
in your program, the code that is compiled depends on whether a preprocessor macro by that
name is defined or not. For example, if there has been a “#define UNIT_TESTING” macro line),
5
the product version here” is ignored. If the macro is not defined, “ add your code
for the product version here” is compiled and “add your unit testing code
here” is ignored.
These macros look a lot like if statements, but macros behave completely differently. More
specifically, an if statement decides which statements of your program must be executed at run
time; #ifdef controls which lines of code in your program are actually compiled.
Unit Testing:
Unit testing is a way of determining if an individual function or class works. You need to isolate a
single function or class and test only that function or class. For each function in this homework,
you need to check normal cases and boundary cases.
Examples for tested values:
– String – empty string, medium length, very long
– Array – empty array, first element, last element
– Int – zero, mid-value, high-value
You must implement a unit test driver for each function implemented in your program. You may
need to use assert() to develop your unit test drivers if tested results are predictable.
Integration Testing:
Integration testing (a.k.a., Integration and Testing) is the phase in software testing in which
individual software modules are combined and tested as a group. You may use the sample user
interface illustrated in Fig. 2 on page 4 to perform an integration testing for your program.
Requirements:
1. (2.5 points) Use comments to provide a heading at the top of your code containing your
name, Auburn UserID, filename, and how to compile your code. Also describe any help or
sources that you used (as per the syllabus).

6. (10 points) A function that creates new quiz from a keyboard. (see step 4)
7. (15 points) A function that asks a question and checks a player’s answer. (see step 5)
8. (15 points) Write a test driver for function implemented in step 5.
9. (10 points) Correctly implement the main function. (step 7)
10. (10 points) Create two versions using conditional compilation.

the TA compiles your source code. You will lose points if you: do not use the specific program file
name, or do not have a comment, or don’t have a commend block on program you hand in.
Programming Environment:
Write a short program in C++. Compile and run it using AU server (no matter what kind of text
editor you use, please make sure your code could run on AU server, the only test bed we accept
is AU server).
Deliverables:
Submit your source code file named as “project4_AUuserID.cpp” through the Canvas system.
Late Submission Penalty:
– Late submissions will not be accepted and will result in a ZERO without valid excuses, in
which case you should talk to Dr. Li to explain your situation.
– GTA/Instructor will not accept any late submission caused by internet latency.
