A start?

i know this solution using private constructor.

So, the user has to call the static method to create the new object. Is there anything better than this.

No, not really. The question you should be asking yourself is why do you need this feature in the first place? Clicky.

#include <iostream.h>
#include <conio.h>

class SealedBase
{
protected:
    SealedBase()
    {
    }
};

#define Sealed private virtual SealedBase 

class Penguin : Sealed
{
};

class BigZ : Penguin
{
};

void main()
 {
BigZ bigZ;//cannot create obj beacuse penguin is sealed
  clrscr();
  cout<<"Sample for selaed":
  getch();
  }
