(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 array(i.e., output the roster). (3 pts)

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
a - Add player
d - Delete player
u - Update player rating
r - Output players above a rating
o - Output roster
q - Quit

(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 “Add player” menu option. Prompt the user for a new player’s jersey number and rating. Append the values to the two arrays. (1 pt)

Ex:

Enter another player's jersey number: 49
Enter another player's rating: 8

(5) Implement the “Delete player” menu option. Prompt the user for a player’s jersey number. Remove the player from the roster (delete the jersey number and rating). (2 pts)

Ex:

Enter a jersey number: 4

(6) 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. (1 pt)

Ex:

Enter another player's jersey number: 23
Enter another player's rating: 6
...

(7) 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. (2 pts)

Ex:

Enter a rating: 5
