Question

1. Define a struct for a soccer player that stores their name, jersey number, and total points scored.

2. Using the struct in #1, write a function that takes an array of soccer players and its size as arguments and returns the average number of points scored by the players.

3. Using the struct in #1, write a function that takes an array of soccer players and its size as arguments and returns the index of the player who scored the most points.

4. Using the struct in #1, write a function that sorts an array of soccer players by name.

5. Using the struct in #1, write a function that takes an (unsorted) array of soccer players and its size and a number as arguments, and returns the name of the soccer player with that number. It should not do any extra unnecessary work.

in c++ please

#include<iostream>
#include<string>
using namespace std;

//struct for a soccer player that stores their name, jersey number, and total points scored
