Write a program IN C# named SalespersonDemo that instantiates objects using classes named RealEstateSalesperson and GirlScout. Demonstrate that each object can use a SalesSpeech() method appropriately. Also, use a MakeSale() method two or three times with each object, and display the final contents of each object’s data fields. First, create an abstract class named Salesperson. Fields include firstName and lastName; the Salesperson constructor requires both these values. Include properties for the fields. Include a method called GetName that returns a string that holds the Salesperson’s full name—the first and last names separated by a space. Then perform the following tasks: Create two child classes of Salesperson: RealEstateSalesperson and GirlScout. The RealEstateSalesperson class contains fields for the following: TotalValueSold - The total value sold in dollars (an int initialized to 0) TotalCommissionEarned - Total commission earned (a double initialized to 0) CommissionRate -…
Consider a class "Fan" with two integer data members, "state" (0/1 i.e. on or off) and "speed". 1. Write a parameterized Constructor for this class. 2. Write a member function "changeState( )" which behaves similar to pressing a button i.e. it should change the state of the fan. If it is off (0), calling the function should turn it on (1) and vice versa.. Multi Line Text.

5. Given the Java Point class (which contains two private variables x and y and constructors that allows creating a point object with known x and y values as well as other methods such as equals( ), toString( ) etc), (a). define a new class called Circle that contains private two variables: center which is a Point object from the Point class and radius which is of type double. The Circle class must have the following methods: (b). add a constructor which creates a circle object using a center point with x and y values and a radius as its parameters. (c). add a default constructor. ( (d). add an equals() method that can compare if any object is equal to a Circle object (two circle objects are equal if they have the same center point with the same radius). (e). add a toString() method that prints a Circle object with the center point and radius.
