Create a simple cashier system Windows application. Name the project as CashierApplication and the form as frmPurchaseDiscountedItem. The application should perform the following specifications: get the item to purchase, price, discount, and quantity; 

 • compute the total amount to purchase; 

 • get the amount of payment then compute the change.  *Figure 2 shows the layout and the required controls for the project.  

Notes:  

• To convert the discount value into a double type, multiply the discount by 0.01 (discount * 0.01).  

• To compute the discounted price, multiply the discount by the regular item price (32% * price),  then subtract the result from the regular price (discounted price = price * result);  

• Use the Convert.ToDouble() and Convert.ToInt32() methods to convert the texts into double or integer types.  2. The application should contain two (2) separate classes: Item and DiscountedItem. The  DiscountedItem class should inherit from the Item class. Make these classes members of the namespace named ItemNamespace. Refer to the UML class diagram in Figure 1 for the required class  members
