Classes and Abtract methods

Question

So I have this plain code here and I'm trying to make sense of these but I end up with a lot of errors and such. The main thing I need to do is to declare a Person class with a Hello abstract method, and then declare a Student class that is derived from the Person class and overrides its Hello method.

here is the code below:

public class Person{
  public abstract void Hello();
}
  class Student: Person {
    public override void Hello() {
 Console.Write("Hello there");
}}

Answer 1

'function' is abstract but it is contained in nonabstract class. A method cannot be an abstract member of a nonabstract class.

Key is A method cannot be an abstract member of a nonabstract class

You need make Person class an abstract class

public abstract class Person
{
    public abstract void Hello();
}
