Create a program for an Ice Cream Shop. The program will store data about ice cream cones and customers.

1. Create a Cone class that includes a choice of ice cream or yogurt, the flavor, the number of scoops and type of cone a. This class should also include static data members for the cost per scoop (.50), cost per ice cream cone (.75)

2. Create a Customer class that includes last name, first name and CustomerID number a. Store the Customer data to a file. You may not have data about the same customer in your file more than once

3. 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)

4. 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

Value Added - something not listed above

Please note: This question has been solved before but I don't see it done with appropriate step by step. Most of the answer I found answered does not have customer class or cone class part. Please answer this question in step by step as it is in question. Please don't miss customer class part.

It is C# question.
