            Console.Write ("India"); 
            break;
    }
    
    if (val > 0)
        Console.Write ("B"); 
    else if (val < 0)
        Console.Write ("X");
}

1. Delegates are not type-safe.
2. Delegate is a user-defined type.
3. Only one method can be bound with one delegate object.
4. Delegates can be used to implement callback notification.
5. Delegates permit execution of a method on a secondary thread in an asynchronous manner.

1. Student[3] = 34;

2. Student s = new Student(); 
   s[3] = 34;

3. Student s = new Student(); 
   Console.WriteLine(s[3]);

4. Console.WriteLine(Student[3]);

5. Student.this s = new Student.this(); 
   s[3] = 34;
