Question

language is C++

1. Design a class that manages a Pet Food Company's quarterly summarized activity. It should contain the following:

( This is all private data )

Company Name - char[40]   //  This is a static member 

Quarter              - char         // This is a static member.  Validate to be 1-4 in the setter method

Division Name - char[40]

BonusBudgetRate - float   - set to 0.02
Total Sales        - float

Total Expenses - float

1a. Create a public method named netIncome() which will return total sales - total expenses as float.

2. Create public class methods (Setters and Getters) that load the data values.

3. Do not create getter/setter methods for the BonusBudgetRate item. It can be set in a constructor or initialized to the default value of 0.02. There is no other reference to it.

4. This class needs a header file and a corresponding cpp file.

5. Create a 'driver' program that contains the main() method and includes the header file for PetFoodCompany class.

   In the driver program, create an instance of the object PetFoodCompany. 

   Internally set the Quarter to 1 and the CompanyName to a name of your choosing.
   Display the CompanyName and Quarter values
   Prompt for total sales and total expenses for this object
   Display the result of netIncome(). 

Below is an example:

Company Name is myCompanyName
Current Quarter is 1

Enter Total Sales: 1000

Enter Total Expenses: 600
Net Income = 400

The deliverable is a working program (CPPs & H files) and a UML diagram of the this class.

UML Diagram:

       float getTotalSales();

       void setTotalSales(float totalSales);

       float getTotalExpences();
       void setTotalExpences(float totalExpences);
double netIncome();
char * getCompanyName();
void setCompanyName(char name[]);
char * getDivisionName();

private:
// Declaring variables
