Array of objects, Bubble Sort, Binary Search

[pik]

This is my first time posting here and I am doing so because I need a little help with an assignment I have for school..I am not asking for the answer but I would greatly appreciate a few hints to get me going in the right direction because after a while my brain just got overloaded and I got VERY confused....
I have done the first part of the question but I am having trouble with number 2..

This is the assignment:
1. Design a class for a sales person that has the following members variable:
 EID: To holds the sales person’s employment ID
 Firstname: To holds the sales person’s first name.
 Lastname: To holds the sales person’s last name.
 Date: To holds the sales person’s birth date
 TotalAnnualSales: To holds the sales person’s total sales in a year.
In addition, the class should have the following member functions.
 Constructor: The constructor should accept the sales person’s data as arguments and assign these values to the object’s member variables. (4 points)
 Mutators: Appropriate mutator functions should be created to allow values to be set for each object’s data members.
 Accessors: Appropriate accessor functions should be created to allow values to be retrieved from an object’s 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.
2. 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 person’s 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..




I am done with the first part of the question but I am having trouble making an array of objects....(How do i make my code look cool like it does in my compiler?)
