C#
Create a program for an Ice Cream Shop. The program will store data about ice cream cones and customers.
Create a Cone class that includes a choice of ice cream or yogurt, the flavor, the number of scoops and type of cone
This class should also include static data members for the cost per scoop (.50), cost per ice cream cone (.75)
Create a Customer class that includes last name, first name and CustomerID number
Store the Customer data to a file. You may not have data about the same customer in your file more than once
Create an Order class that includes a Customer object and an array of 10 Cone objects (the maximum number of ice cream cones a customer can order is 10)
Display all order information and totals
Your application must include the following:
Constructors
Delegate
Arrays
Abstract Class or Interface
Exception Handling
Static Data Members
Overloaded Operator or overridden method
MessageBox
Inheritance
Data Validation
File Input/Output
