Let ‘s assume that you will design a class called Order. Order class will have data members as: int orderID, double orderAmountTotal, string OrderDescription, Date orderDate. Date is a class, which has month, day and year as data members. As we know, to be a valid orderDate, you have to take leap year as consideration.

If you do, you might get partial credit and no credit.
