Inheritance - Part - 2

Example
 We start with an example:

class A
  {
    void Hello()
    {
     Console.WriteLine(―Hello, World!‖);
    }
  }
class B:A
 {
  void Hai()
   {
    Console.WriteLine(―Hai to all!‖);
   }
 }


• In  the  above  example,  we  have  two  classes  called  " A "  and " B ".  The  inheritance relationship has been established between these classes. Now, the " A " class is called as "Super "  class  and " B "  class  is  called  as  "Sub"  class.  All  the  members  of  "A"  class  are exactly copied into "B" class. Finally, whenever you construct an object for the "B" class, you can access both "Hello()" method and "Hai()" method also from that object. This is what we learned up-to-now.
• But  sometimes,  some  of  the  super  class  members  may  not  be  accessible  directly  from the sub class‘s object. This kind of nature depends on the "access modifiers", we use in the super class, while we declare the super class members.
