[Solved] COMP2710 Homework 5-a simple trivia quiz game

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 structure; no array is allowed in this homework assignment. Then, your program asks a question to the player, input the players answer, and check if the players answer matches the actual answer. If so, award the player the award points for that question. If the player enters the wrong answer your program should display the correct answer. 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: Creating 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)
  • Answer: 38
  • Award points: 100 o Trivia 2:
  • Question: What was Bank of Americas original name? (Hint: Bank of Italy or Bank of Germany)
  • Answer: Bank of Italy
  • Award points: 50 o Trivia 3:
  • Question: What is the best-selling video game of all time? (Hint: Call of Duty or Wii Sports)?
  • Answer: Wii Sports
  • 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 players answer, and check if the players answer matches the actual answer. If so, award the player the dollar amount for 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 indicate 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 1 on page 3 for the sample user interface.) o Case 1: ask 0 question.
  • Case 2: ask 1 question (i.e., the first one) from the list.
    • Correct answer
    • Wrong answer
  • Case 3: ask 3 questions (i.e., all the questions) from the list.
    • Correct answers
    • Wrong answers
  • 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,
• input the players answer,
• if the players 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 the correct answer.

o When all questions have been asked display the total award points the player has won.

• Step 8: Creating two versions using conditional compilation.

• Version 1: simply run the test driver implemented in Step 6.
• 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. The user input is depicted as Bold, but you do not need to display user input in bold. In this version, your program must run the test driver you build in Step 6.

Fig. 1. Sample user interface for the debug version.

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 Xiao Qin with your name. In this version, your program must run the test driver you build in Step 6.

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

add your unit testing code here

#else

add your code for the product version here

#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), then add your unit testing code here is compiled and add your code for 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.
