This program will store roster and rating information for a soccer team. Coaches rate players during tryouts to ensure a balanced team. (1) Prompt the user to input five pairs of numbers: A player's jersey number (0 - 99) and the player's rating (1 - 9). Store the jersey numbers in one int array and the ratings in another int array. Output these arrays (i.e., output the roster). Ex: Enter player 1's jersey number: 84 Enter player 1's rating: 7 Enter player 2's jersey number: 23 Enter player 2's rating: 4 Enter player 3's jersey number: 4 Enter player 3's rating: 5 Enter player 4's jersey number: 30 Enter player 4's rating: 2 Enter player 5's jersey number: 66 Enter player 5's rating: 9 ROSTER Player 1 -- Jersey number: 84, Rating: 7 Player 2 -- Jersey number: 23, Rating: 4 (2) Implement a menu of options for a user to modify the roster.

The program ends when the user chooses the option to Quit. For this step, the other options do nothing. Ex: MENU u - Update player rating a - Output players above a rating r - Replace player o - Output roster q - Quit Choose an option: (3) Implement the "Output roster" menu option. (1 pt) Ex: ROSTER Player 1 -- Jersey number: 84, Rating: 7 Player 2 -- Jersey number: 23, Rating: 4 (4) Implement the "Update player rating" menu option. Prompt the user for a player's jersey number. Prompt again for a new rating for the player, and then change that player's rating. Ex: Enter a jersey number: 23 Enter a new rating for player: 6 (5) Implement the "Output players above a rating" menu option. Prompt the user for a rating. Print the jersey number and rating for all players with ratings above the entered value. Ex: Enter a rating: 5 ABOVE 5 Player 1 -- Jersey number: 84, Rating: 7 (6) Implement the "Replace player" menu option. Prompt the user for the jersey number of the player to replace. If the player is in the roster, then prompt again for a new jersey number and rating. Update the replaced player's jersey number and rating. 0 Ex: Enter a jersey number: 4 Enter a new jersey number: 1 2 Enter a rating for the new player: 8 84 7 23 4 4 5 30 2 66 9 q Your output starts with Enter player 1's jersey number (0 - 99): Enter player 1's rating (1 - 9): Enter player 2's jersey number (0 - 99): Enter player 2's rating (1 - 9): Enter player 3's jersey number (0 - 99): Enter player 3's rating (1 - 9): Enter player 4's jersey number (0 - 99): Enter player 4's rating (1 - 9): Enter player 5's jersey number (0 - 99): Enter player 5's rating (1 - 9): MENU a - Add a player o - Output roster u - Update player rating a - Output players above a rating r - Replace player q - Quit Choose an option: Expected output starts with Enter player 1's jersey number: Enter player 1's rating: Enter player 2's jersey number: Enter player 2's rating: Enter player 3's jersey number: Enter player 3's rating: Enter player 4's jersey number: Enter player 4's rating: Enter player 5's jersey number: Enter player 5's rating: ROSTER Player 1 -- Jersey number: 84, Rating: 7 Player 2 -- Jersey number: 23, Rating: 4 Player 3 -- Jersey number: 4, Rating: 5 Player 4 -- Jersey number: 30, Rating: 2 Player 5 -- Jersey number: 66, Rating: 9

Question
This program will store roster and rating information for a soccer team. Coaches rate players during tryouts to ensure a balanced team.
(1) Prompt the user to input five pairs of numbers: A player's jersey number (0 - 99) and the player's rating (1 - 9). Store the jersey numbers in one int array and the ratings in another int array. Output these arrays (i.e., output the roster).
Ex:
Enter player 1's jersey number:
84
Enter player 1's rating:
7
Enter player 2's jersey number:
23
Enter player 2's rating:
4
Enter player 3's jersey number:
4
Enter player 3's rating:
5
Enter player 4's jersey number:
30
Enter player 4's rating:
2
Enter player 5's jersey number:
66
Enter player 5's rating:
9
ROSTER
Player 1 -- Jersey number: 84, Rating: 7
Player 2 -- Jersey number: 23, Rating: 4
(2) Implement a menu of options for a user to modify the roster. Each option is represented by a single character. The program initially outputs the menu, and outputs the menu after a user chooses an option. The program ends when the user chooses the option to Quit. For this step, the other options do nothing.
Ex:
MENU
u - Update player rating
a - Output players above a rating
r - Replace player
o - Output roster
q - Quit Choose an option:
(3) Implement the "Output roster" menu option. (1 pt)
Ex:
ROSTER
Player 1 -- Jersey number: 84, Rating: 7
Player 2 -- Jersey number: 23, Rating: 4
(4) Implement the "Update player rating" menu option. Prompt the user for a player's jersey number. Prompt again for a new rating for the player, and then change that player's rating.
Ex:
Enter a jersey number:
23
Enter a new rating for player:
6
(5) Implement the "Output players above a rating" menu option. Prompt the user for a rating. Print the jersey number and rating for all players with ratings above the entered value.
Ex:
Enter a rating:
5
ABOVE 5
Player 1 -- Jersey number: 84, Rating: 7
(6) Implement the "Replace player" menu option. Prompt the user for the jersey number of the player to replace. If the player is in the roster, then prompt again for a new jersey number and rating. Update the replaced player's jersey number and rating. 0
Ex:
Enter a jersey number:
4
Enter a new jersey number: 1
2
Enter a rating for the new player:
8 84 7 23 4 4 5 30 2 66 9 q
Your output starts with
Enter player 1's jersey number (0 - 99): Enter player 1's rating (1 - 9): Enter player 2's jersey number (0 - 99): Enter player 2's rating (1 - 9): Enter player 3's jersey number (0 - 99): Enter player 3's rating (1 - 9): Enter player 4's jersey number (0 - 99): Enter player 4's rating (1 - 9): Enter player 5's jersey number (0 - 99): Enter player 5's rating (1 - 9): MENU a - Add a player o - Output roster u - Update player rating a - Output players above a rating r - Replace player q - Quit Choose an option:
Expected output starts with
Enter player 1's jersey number: Enter player 1's rating: Enter player 2's jersey number: Enter player 2's rating: Enter player 3's jersey number: Enter player 3's rating: Enter player 4's jersey number: Enter player 4's rating: Enter player 5's jersey number: Enter player 5's rating: ROSTER Player 1 -- Jersey number: 84, Rating: 7 Player 2 -- Jersey number: 23, Rating: 4 Player 3 -- Jersey number: 4, Rating: 5 Player 4 -- Jersey number: 30, Rating: 2 Player 5 -- Jersey number: 66, Rating: 9
