House - C# Programming Exercise

In this exercise, you need to create a class called "House" with an attribute called "area". The class should have a constructor to set the value of this attribute, as well as a method called "ShowData", which will display the message "I am a house, my area is 200 m2" (instead of 200, the actual area will be shown). Additionally, you should include getters and setters for accessing and modifying the house area.

The House class will also contain a door. Each door will have an attribute "color" (a string) and a method "ShowData", which will display the message "I am a door, my color is brown" (or whatever the actual color is). Like with the area, getters and setters should also be created for the door color. Moreover, you need to create a GetDoor method in the "House" class that will return the door.

The exercise also involves a subclass called "SmallApartment", which is a subclass of "House" with a preset area of 50 m2.

Additionally, you need to create a Person class, with a name (string) and a "House" property to store the person's house. The ShowData method for the "Person" class will display the person's name, the house data, and the door data of the house.

Finally, you need to write a Main method that creates a "SmallApartment", a person to live in it, and displays all the data about the person and their house.

House

 Objective

Create a class "House", with an attribute "area", a constructor that sets its value and a method "ShowData" to display "I am a house, my area is 200 m2" (instead of 200, it will show the real surface). Include getters an setters for the area, too.

The "House" will contain a door. Each door will have an attribute "color" (a string), and a method "ShowData" wich will display "I am a door, my color is brown" (or whatever color it really is). Include a getter and a setter. Also, create a "GetDoor" in the house.

A "SmallApartment" is a subclass of House, with a preset area of 50 m2.

Also create a class Person, with a name (string). Each person will have a house. The method "ShowData" for a person will display his/her name, show the data of his/her house and the data of the door of that house.

Write a Main to create a SmallApartment, a person to live in it, and to show the data of the person.
