Question

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 update the data of a player. (You may assume that 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. 7 Adhere to the programming standards that I've covered (no global arrays, input validation, etc.)

In C++:

Functions to include:

editPlayer: is a void fn, which takes an array of playerType and calls
lookUpPlayer which returns the index of the target (-1 if not found).
If found allows the user to edit any of the data members of the player via a menu system.
lookUpPlayer: is a int fn, which takes an array of playerTypes, prompts the user for the
name of the player and attempts to find them. If found, prints message "found" and returns the index,
otherwise prints "not found" and returns -1. ** Extra credit 2 pts if you make it case insensitive and
substrings work (i.e. "lex" is found in the string "Lexacon".
printPlayer is a void fn, that that takes a playerType variable by value and prints a single players' record.
printTeam, is a void fn, takes the entire array and calls printPlayer for each record.
readFile, is a void fn which populates the array from a file "input.txt" make it local
writeFile, is a void fn which saves the database to "output.txt"

InFile Contents (no user inputs, just read inputs from the below contents):
