Write definition of a class that has the following properties.
Question
Write definition of a class that has the following properties.
The name of the class is Sales.
The class Sales has the following member variables:
id (string)
year (int)
name (string),
amountSold (int),
The class Sales has the following member functions:
Constructors:
default constructor
overloaded constructor
Setters:
setId – sets the id
setYear – sets the year
setName – sets the name
setAmount – sets the amount sold
Getters:
getId – returns the id
getYear – returns the year
getName – returns the name
getAmount – returns the amount sold
Other functions:
display – outputs the data in the member variables, the commission percent and amount earned as shown below (see sample output).
detAmountEarned – determines the amount earned based upon their sales.
detCommissionPercent – determines the commission percent based on the following table:
SalesCommissionBelow $10003%$1001 – $50004.5%$5001 – $10,0005.25%over $10,0006%
Write definitions of all the member functions of class Sales.
Finish writing the test driver for this class
Sample Output:
Testing the first object:
ID: 20192785
Year: 2017
Name: Jane North
Amount Sold: $10000
Commission: 5.25%
Amount Earned: $525

Summary
Here main three files are created naming as Sales.h, Sales.cpp and main.cpp. Sales.h is here the header file for class sales. In the main.cpp there is a main method. Where every function is declared. There is a constructor and function in every header file.
Explanation
Here three different program has been written. Where each class has its own different header file. Name of the header file is Sales.h, Sales.cpp and main.cpp. There are a class Sales in the sales.h header file. So the data member of the class is name, year, id and getnd amountSold with the access identifier private. And also there are constructors, functions, setter and getter. After that in the next program, there is a new header file called Sales.cpp which includes the old header file sales.h. Next we define a definition of constructors and functions based on the user specification. After that there is a new class with a new header file where both the previous header files are added.
