CIS 170 Week 5 iLab 5 of 7 Tournament Stats and Alphabetical Order Program

Part A: Tournament Stats

Requirements
Your mission: Write a program to determine statistics for a video game tournament. The user will input names and scores of all tournament players. The program will calculate the average score and display the players who scored below average.

The program will implement these functions:
• Main(): Declares variables for the number of players and average score, and two arrays of size 100: one to store player names and the other to store their respective scores. Calls the following functions in sequence, passing necessary parameters by reference:
InputData( ): Gets player names and scores from the user and stores them into the two arrays for an unknown number of players up to 100.
DisplayPlayerData(): Displays each player’s name and score.
CalculateAverageScore( ): Calculates the average score and returns it by value.
DisplayBelowAverage( ): Displays the names and scores of players who scored below average.

Sample output:
Enter Player Name (Q to quit): Bob
Enter score for Bob: 3245
Enter Player Name (Q to quit): Sue
Enter score for Sue: 1098
Enter Player Name (Q to quit): Dave
Enter score for Dave: 8219
Enter Player Name (Q to quit): Pat
Enter score for Pat: 3217
Enter Player Name (Q to quit): Q

Name Score
Bob 3245
Sue 1098
Dave 8219
Pat 3217

Average Score: 3944.75
Players who scored below average

Name Score
Bob 3245
Sue 1098
Pat 3217

Tips
Best practices: Don’t try to write too much at a time! First, write an outline in comments based on the requirements and the pseudocode. Then, implement each function one at a time. Start each by writing a shell that just accepts data and perhaps prints it out for testing purposes. Test by calling the function from Main(). Then, add more functionality. Keep working incrementally, compiling and testing as you go. Set breakpoints and use the debugger at each phase to make sure your logic is working correctly. Then, use the same approach to implement each of the other functions.
Pseudocode
• Main Function
Declare player and score arrays, and variables for number of players and average score.
Call the InputData( ) function, passing arrays and number of players variable by reference
Call the DisplayPlayerData( ) function, passing arrays and number of players variable by reference
Call the CalculateAverageScore( ) function, passing arrays and number of players by reference. Store returned value in average variable.
Display the average score
Call the DisplayBelowAverage( ) function, passing arrays and number of players variable by reference, passing average variable by value

• InputData function
Loop while the number of players is less than the length of the array
Prompt for the player’s name
If the user entered Q, break out of the loop
Prompt the user for the player’s score
Add 1 to the number of players

• DisplayPlayerData function
Loop to display the name and score of each player

• CalculateAverageScore function
Loop to add up the scores
Divide by the number of players to calculate the average score
Return the average score to main

• DisplayBelowAverage function
Loop to display the names and scores of all players who scored below the average score

END OF PART A

Part B: Alphabetical Order
Requirements
Your mission: Write a program to alphabetize a list of last names. The user will input an undetermined number of last names. The program will display the number of names entered and alphabetized lists of the names in ascending (A-Z) and descending (Z-A) order.

Your program will store the names in an ArrayList object. It will use various ArrayList properties and methods to implement the program requirements.
Sample output:

Enter a last name: Roberts
Keep going? (Y/N): y
Enter a last name: DeLay
Keep going? (Y/N): y
Enter a last name: Foreman
Keep going? (Y/N): y
Enter a last name: Ganguly
Keep going? (Y/N): n
4 last names entered

Names in Ascending Order
DeLay
Foreman
Ganguly
Names in Descending Order
Roberts
Ganguly
Foreman
DeLay

Tips
Best practices: Don’t try to write too much at a time! First, write an outline in comments based on the requirements and the pseudocode. Then, work on instantiating an ArrayList object, followed by implementing the loop that will get user input. As always, keep things simple and implement incrementally. Review the list of ArrayList methods and properties in the textbook and experiment with the ones you think you’ll need.
Pseudocode
• Main function
• Instantiate ArrayList object
• Loop to get last names, until user wants to quit
o Add each last name to the ArrayList
• Display the count of the last names
• Sort the ArrayList
• Loop to display the names
• Reverse the order of the ArrayList
• Loop to display the names
