You will design various classes and write a program for calculating how much a property agent might earn in a year through selling properties: Data Structure Assignment, SP, Singapore

In this assignment, you will design various classes and write a program for calculating how much a property agent might earn in a year through selling properties.

a. Create a Property class with an address, 6 digit postal code number, tenure, completion year, property type, area, commission rate and valuation. Add appropriate constructors and member functions to initialize, access, and manipulate the data members. Commission rate is default to 1%.

b. Design the class CommercialProperty, that extends from the class Property, with an additional data member to store the commercial property type (for office, flatted factory, factory). Add appropriate constructors and member functions to initialize, access, and manipulate the data members.

c. Create a PropertyAgent class that holds 2 list of properties. One list of properties held are the ones that the property agent has not sold, while another list of properties holds the properties sold by the agent during the year. The PropertyAgent would also have data members commission sharing rate default to 70%, the company he worked for, his/her agent registration number and the year the agent began working.

d. Design the class PropertyAgencyDirector that extends from the PropertyAgent class with an additional data member default to 5% to a maximum of 15% of the commission earned by the agent and a list of agents working under him/her. The commission sharing rate is now default to 75% and is at maximum 90% of commissions earned.

e. Design the class CommissionSlip to calculate and display an agent’s commission earned for the year based on the properties sold (based on the commission rate) multiplied by the commission sharing rate. Eg. If the agent sold a property worth $1 million with commission rate of 1% and his sharing rate is 70%, the commission earned will be $1,000,000 * 0.01 * 0.7 = $7,000. If the agent is a Property Agent Director, then he/she will have overriding commission of his/her agents at the rate. The commission slip shall therefore show the breakdown of commissions earned per property, the commission sharing for each property, the total commission earned for the property agent. If the agent is a directory, there will be the breakdown of the overriding income for each agent and the total overriding income earned as well as the total income earned.

f. Write a program to create at least 2 different directors with at least 3 different agents each. Each agent shall hold at least 5 properties that are unsold and 3 to 10 properties sold per agent. Print the commission slip for each agent and director.
