Question

In an Application console Project, Give instructions that:

- Create a class "Person"

- Create two classes “Student” and “Teacher”, both inherit from the class "Person".

- The class "Student" will have a public method "GoToClasses", which will display on the screen "I’m going to class. ".

- The class "Person" must have a method "SetAge (int n)" which will indicate the value of their age (for example, 20 years old).

- The class "Student" will have a public method "DisplayAge" which will write on the screen "My age is: XX years old".

- You must create another test class called "Test" which will contain "static void Main()" .

- Create a Person object and make it say "Hello"

- Create a Student object, set its age to 20, make it say "Hello", “I'm going to class. And display his age. - Create a Teacher object, 50, ask him to say "Hello" and then begin the course.
