Question

C++ Chapter 4/5 Lab Assignment Using concepts from chapters 1 – 5 only. Grading will be based on chapter 4 concepts more. Design a menu driven program that can keep track of five player’s scores. Your program must have the following documentation: A. Your name B. The program name C. Program Description D. The date the exe file was created E. The code: a. Use a menu approach do the following: i. to Add a player information ii. to Search for any player based on their name. iii. to Display all the information at any time (Hint : Use value and reference parameters as necessary).. b. Organize the main program to call input and output functions. Use static variables to keep track of player’s information. c. Input the names of five players and their highest scores on three games they ever played. Do Not Hard-Code the players’ names and their scores. d. Create an average function to compute the average highest score of each player i.e. ( john: g1 100 g2 200 g3 300. Average highest score will be 200.00).
