Return a Reference to a Scoreboard Slot

Fill in int &slotAt(int scores[], int index) so it returns the element at position index. The starter returns scores[0] as a placeholder - replace it with the right element.

main is already written and does this:

    int scores[5] = {10, 20, 30, 40, 50};
    slotAt(scores, 2) = 99;
    slotAt(scores, 4) = slotAt(scores, 0) + 5;

then prints all five elements, one per line. The program must print exactly the output shown in Expected Output.
