Hello,
I have spent copious amount of time on this code, and I don't know if I really don't understand the issue, or if my brain is just fried at this point, but I just cannot figure out what to change:) The prompt is below.
The error messages are mostly about my for loops, saying that I have comparison between signed and unsigned integer expressions.
~~~~~~~~~~~~~~~~~
main.cpp: In function ‘int main()’:
main.cpp:53:18: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
for (i = 0; i < jersey.size(); i++) {

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). (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. (2 pts)
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. (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 vectors. (1 pt)
Ex:
Enter a new player's jersey number:
49
Enter the 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 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. (2 pts)
Ex:
Enter a rating:
5
ABOVE 5
Player 1 -- Jersey number: 84, Rating: 7
...
