Chapter 10, Problem 1E
Create an application class named LetterDemo that instantiates objects of two classes named Letter and CertifiedLetter and that demonstrates all their methods. The classes are used by a company to keep track of letters they mail to clients. The Letter class includes auto-implemented properties for the name of the recipient and the date mailed. Also, include a ToString() method that overrides the Object class’s ToString() method and returns a string that contains the name of the class (using CetType and the Letter’s data field values. Create a child class named CertifiedLetter that includes an auto-implemented property that holds a tracking number for the letter.

- This has to be done in visual studio, c# windows form application (.net fromework). Question: The application should be able to do the following :• Create a class called Person which contains 4 private fields : Name(string), Surname (string),Course(string), CRNumber(int).• The class must contain 4 public properties which will be used to get and set the values of the private fields.• The class must contain a default constructer. The class must also contain an overloaded constructer which should be able to set the values of each of the private fields.• The class must contain a static ViewInfo method which will be used to display information of a queue of person objects back to the user neatly grouped underneath each other as displayed above.• Once a user clicks on the “Add Person” button then the information in the respective textboxes should be used to create a Person object (using the properties or the overloaded constructor) and add it to a queue which is of type Person.

The class includes methods to get each field. In addition, create a default constructor that automatically sets the activity to running, the minutes to 0, and the date to January 1 of the current year. Save the file as FitnessTracker.java. Create an application that demonstrates each method works correctly, and save it as TestFitnessTracker.java. b - Create an additional overloaded constructor for the FitnessTracker class you created in Exercise 3a. This constructor receives parameters for each of the data fields and assigns them appropriately. Add any needed statements to the TestFitnessTracker application to ensure that the overloaded constructor works correctly, save it, and then test it. c - Modify the FitnessTracker class so that the default constructor calls the three-parameter constructor.
