Question

(C++) Write a program that declares a struct to store the data of a football player (player’s name, player’s position, number of touchdowns, number of catches, number of passing yards, number of receiving yards, and the number of rushing yards).

Declare an array of 10 components to store the data of 10 football players.

Your program must contain a function to input data and a function to output data. Add functions to search the array to find the index of a specific player, and up-date the data of a player. (You may assume that the input data is stored in a file.) Before the program terminates, give the user the option to save data in a file. Your program should be menu driven, giving the user various choices.

The name of the data filename provided is Ch9_Ex7Data.txt

An example of the program is shown below:

Select one of the following options:                                 
1: To print a player's data                                          
2: To print the entire data                                          
3: To update a player's touch downs                                  
4: To update a player's number of catches                            
5: To update a player's passing yards                                
6: To update a player's receiving yards                              
7: To update a player's rushing yards                                
99: To quit the program                                              
1                                                                    

Enter player's name: Bill                                            

Name: Bill Position: Quarter_Back;  Touch Downs: 70;  Number of Catche
s: 0;  Passing Yards: 8754;  Receiving Yards: 0;  Rushing Yards: 573  

Select one of the following options:                                 
1: To print a player's data                                          
2: To print the entire data                                          
3: To update a player's touch downs                                  
4: To update a player's number of catches                            
5: To update a player's passing yards                                
6: To update a player's receiving yards                              
7: To update a player's rushing yards                                
99: To quit the program                                              
99                                                                   

Would you like to save data: (y,Y/n,N) N
