IMPORTANT:

• The use of vectors is not allowed

This program will store roster and rating information for a basketball team. Coaches rate players during tryouts to ensure a balanced team. A roster can include at most 10 players.

(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.

Ex:

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

Choose an option:

(3) Implement the "Output roster" menu option.

Ex:

ROSTER
Player 1 -- Jersey number: 84, Rating: 7
Player 2 -- Jersey number: 23, Rating: 4
...

(4) Implement the "Add player" menu option. If the user chooses this option and the roster is full, print the following error message:

Impossible to add new player: roster is full.

If the roster is not full, prompt the user for a new player's jersey number and rating, and append the values to the two arrays.

Ex:

Enter a new player's jersey number:
49
Enter the player's rating:
8

(5) Implement the "Delete player" menu option. If the user chooses the option when the roster is empty, immediately print the message:

Can not delete from empty roster.

If the roster is not empty, prompt the user for a player's jersey number. Remove the player from the roster (delete the jersey number and rating), paying attention not to leave unused spaces in the two arrays.

Ex:

Enter a jersey number:
4

If the given jersey number is not found, inform the user:

Error! Player  not found.

(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 look up and change that player's rating.

Ex:

Enter a jersey number:
23
Enter a new rating for player:
6

In this case, if the given jersey number is not found, no further action is taken (note that the format of the program requires both input either way).

(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.

Ex:

Enter a rating:
5

ABOVE 5
Player 1 -- Jersey number: 84, Rating: 7
...

If no players are found above a given rating, the program will simply produce an empty list.

BONUS

For an extra 10 points, implement a secret option s that prints the message:

Executing secret option!

and sorts the roster by jersey number. Do not add this option to the MENU message. And remember to move the player rating accordingly!
