(C++ program)

Design a class for a sales person that has the following members variable:

--EID: To holds the sales persons employment ID

--Firstname: To holds the sales persons first name.

--Lastname: To holds the sales persons last name.

--Date: To holds the sales persons birth date

--TotalAnnualSales: To holds the sales persons total sales in a year.

In addition, the class should have the following member functions.

--Constructor: The constructor should accept the sales persons data as arguments and assign these values to the objects member variables.

--Mutators: Appropriate mutator functions should be created to allow values to be set for each objects data members.

--Accessors: Appropriate accessor functions should be created to allow values to be retrieved from an objects data members.

--calculateCommission: This function should calculate and display the commission amount for a sales person based on his totalAnnualSales. See below

TotalAnnualSales	Commission Percentage
Under $10,000	No commission
$10,000-$20,000	2% of TotalAnnualSales
Greater than $20,000	4% of TotalAnnualSales

Demonstrate the class in a program that creates a sales person object, and then calls each of the functions in the class.

--With the sales person class design in question #1 above in hand, write a program

--To have an array of sales person objects. The program should read and store information for each sales person in each of the object. It should then call a class function, once for each object, to display the sales persons ToalAnnualSales amount and commission amount.

--This program should use bubble sort to sort the array of sales person objects. It places sales person objects in ascending order by their first name.

--Demonstrate the binary search method in this program to search by first name.
