Hi

By creating all constructor private we never create any object of that unless untill we provide any static function or friend calss of it. Again if we do so we can only create the object using new(). So have we to manage the memory efficiently. Again Our question was write a class such that no other class can inherit it means we can create a object of that class.

Or the other way to your answer is to make the dystructor private. By this way you never create any object of that calss beside creating all constrcutor private.

Again the class

class temp

{

private:

temp();

friend

}

Unlike java's final or .NET's sealed C++ doesn't give any inbuilt method to do this. But it can be achieved by some indirect(may be weird ) method. The main disadvantage of this method is that the objects of the class can be created only dynamically. I'm here with attaching the code.

class Base

{

public:

static Base* Instantiate()

{

return (new Base);

}

//What ever members you want to add

private:

Base()

{

cout<<endl<< Object Created Successfully ;

}

};

//********The following class cause ***error***

class Derived : public Base

{

};

//*********Error causing class ends here***********

int main()

{

Base *b NULL;

b Base::Instantiate();

if(b NULL)

cout<<endl<< Object Creation Failed! ;

return 0;

}
