Best ResponseYou've already chosen the best response.2If you might have more than 2**32 elements in your array, you need unsigned long, otherwise it would be overkill.

Best ResponseYou've already chosen the best response.0array indices can be negative numbers as well. But you must know that the elements preceding the base element are a part of your array. So it depends on you whether to make the indices unsigned or not.
