Access Modifiers Practice

You are given a class named Person with a field to store the name. Additionally, there are two classes named Student and Teacher which derive from Person.

There are some errors in the program because of some incomplete code. Your task is to complete the code by:

Making both Student and Teacher inherit from thePerson class;
Ensure that the name field is accessible in the child classes but inaccessible from anywhere else.

index.cs


              12345678910111213141516171819202122232425262728293031323334353637383940414243444546
            
using System;

public class Person
{
    // Field to store the name
    string name;
}

public class Student
{

    public Student(string name)
    {
        this.name = name;
    }

    public void Study()
    {
        Console.WriteLine($"{name} is studying.");
    }
}

public class Teacher
{
    public Teacher(string name)
    {
        this.name = name;
    }

    public void Teach()
    {
        Console.WriteLine($"{name} is teaching.");
    }
}

public class Program
{
    public static void Main(string[] args)
    {
        Teacher t = new Teacher("Hannah");
        Student s = new Student("Mark");

        t.Teach();
        s.Study();
    }
}
