Choose a data type that will contain the values you are working with
(like long)  Your paticular addition is 1 over the size of positive
values that you can cram into an int (2147483647).

A good exercise for a student is to look at the input and determine if
it is valid (or in this case watch the running total); that's probably
being saved for a future assignment.
