Question

C++

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 vector and the ratings in another int vector. Output these vectors (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. Following the initial 5 players' input and roster output, the program outputs the menu. The program should also output the menu again 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 - 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. Be sure to write a separate function for each 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. Prompt the user for a new player's jersey number and rating. Append the values to the two vectors.

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). Be sure to keep the same relative order of all values in the vectors.

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.

Ex:

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

Ex: Enter a rating: 5 ABOVE 5 Player 1 -- Jersey number: 84, Rating: 7 ...

#include <iostream>
