I need the following done in visual studio
Design and implement a C# class for items that can be sold via a point-of-sale system for a coffee shop. Design and implement at least two other classes derived from your first class. Each class must have at least one method and at least two attributes. Make sure your derived classes add additional attributes and/or methods.
Write a sample application that is either console- or forms-based that instantiates one of each of your objects and use the "ToString()" method (defined by default for all C# objects) to output meaningful data for each of your classes as they are instantiated.
Instantiate that class via your console application and display (via a "ToString" method that you implement) the details of that object.
This needs to be completed by Sunday, July 13th 2014.
