(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: 84Enter player 1's rating: 7Enter player 2's jersey number: 23Enter player 2's rating: 4Enter player 3's jersey number: 4Enter player 3's rating: 5Enter player 4's jersey number: 30Enter player 4's rating: 2Enter player 5's jersey number: 66Enter player 5's rating: 9ROSTERPlayer 1 -- Jersey number: 84, Rating: 7Player 2 -- Jersey number: 23, Rating: 4...
