Question

C++ Language

Overview: Design an APP for a basketball team with a unique name. There should be at least 10 players. The member variables required include team member’s names, jersey number, position played, and at least 3 stats. Positions are small forward, power forward, center, shooting guard and point guard. 1. A.) Design a class with member variables and appropriate member functions Data should be stored in a read/write file consisting of team member’s names, jersey number, position played, and at least 3 stats. Use an enumeration for at least one member variable 2. Use a header file for all declarations Create at least two constructors and initialize Create a destructor Create a text based menu to perform the following functions which will loop until the user selects Number 8 for Quit: 3. Enter “1” OPEN ( Add any function you need for your team) 4. Enter “2” Add or replace team members as needed along with their information. 5. Enter “3” Identify the top players based on stats. The number to identify depend on the number needed i.e. for basketball there are 5 players who will be the starters. 6. Enter “4” search by player name and other stats as requested by user. 7. Enter “5” sort by player name or stats as requested by user. 8. Enter “6” to print all data. to screen Display sports team member’s names, jersey number, position played, and at least 3 stats Example stats: on the basketball team there are points scored, assists, rebounds and errors. 9. Enter “7” to print all data to file. 10.Enter “8” to Quit Add any classes, variables or member functions as needed to round out your program. The minimum requirements above must be included.

Mandatory Inclusion of programming concepts:

1. Object Oriented design
   1. Header files
      1. classes
      2. constructors at least two
      3. destructor
2. Input from user
3. processing based on your requirements to include arrays to store data as needed.
4. Output to screen
   1. Decision structure at least one of the following
      1. IF then else structure
      2. Switch
   2. Repetition structure or loop
5. Output to file
6. Functions
   1. Set or Mutators parameters passed in
   2. Get or Accessor functions
   3. Other functions as needed
7. Menu which loops until user selects QUIT

OPTION 1 -

int total[len] = {0}; ****Says there is a problem with "len" here, needs to be a constant
