MCC - CIS162AD CS8 Classes - 15 points

There are 2 object-oriented programming assignments (CS8 and CS9) that build on each other, so CS9 may NOT be started until CS8 has been completed.

Description:
For CS8 create two class definitions: one for customer information, one for the items ordered (see the class diagrams below). The order class should perform the calculations and maintain the summary information in shared (static) variables. Classes are just a definition of a data type. A program that is written to test the classes is referred to as a driver. The driver and class design is provided (see below), so students basically just need to enter the code for the class definitions. The driver program should work as is if the suggested variable and method names listed in the UML Class Diagrams are used.

How to Complete Assignment:

• The form file and skeleton class files for this assignment are provided as a self-extracting archive. It also includes the program code (driver) that must be used to test the class definitions.
• Download and expand the self-extracting archive CS8 Classes
• Open the solution file (CS8.sln).
• Note: There will be many undeclared variables until the required classes are defined and the Preferred Discount checkbox is not used until CS9.
• Use the UML Class Diagram below to determine the variables, property methods, and constructors that should be included in each of the two classes (clsCustomer, clsOrder). The diagram also specifies which access modifier to apply to each item in the class (public, private, or protected).
• In order for the program to work as provided, you should use the variable and method names provided in the UML Class Diagram when building the class definitions. If you deviate from the suggested names, the corresponding changes will need to be made to the source code provide.
• We will NOT be including data validation in this assignment, so the set methods should NOT include any If statements to validate the data. To test data validation included in class definitions would require us to throw an exception, but that is beyond the scope of this assignment :-(.
  
  

Sample form:

Test Data:

Enter any name and address to see if the data displays as a mailing label.

Description	Quantity	Price	Extension
Flower Pot	2	19.95	39.90
Mailbox	1	24.95	24.95
Planter	3	21.95	65.85
Totals:	3		130.70

Partial Code included in Order Class:

public class clsOrder
{
  //declare class variables
  //declare constructors
  //declare property methods

  //declare read-only properties
    public decimal ExtendedPrice 
    {
        get
        {
            return cdecExtendedPrice;
        }
    }

  //declare Shared (static) ReadOnly Properites
    public static decimal TotalPrice 
    {
        get
        {
            return cdecTotalPrice;
        }
    }

    public static int TotalCount 
    {
        get
        {
            return cintTotalCount;
        }
    }

  //declare supporting methods
    public void calcExtendedPrice()
    {
        cdecExtendedPrice = cintQuantity * cdecPrice;
    }

    public void accumulateTotals()
    {
        cdecTotalPrice += cdecExtendedPrice;
        cintTotalCount += 1;
    }

    public static void resetTotals()
    {
        cdecTotalPrice = 0;
        cintTotalCount = 0;
    }

}//End of Class

Submit the two class files: clsCustomer.cs and clsOrder.cs
