Requirements. Modify the cashier\'s logic from the previous lab so that it works for a line of 8 items <I>or less</I>. You can assume that the customer will present at least one item for purchase, and not more than 8 (but you might want to think about how you would handle this if no items are presented, or if more than 8 are presented). Your branching logic will have to include something like this: "If there is no 5th item, skip to line...". 이게 문제구요
