Answer / cpp master
Using virtual base classes. The most derived class has to
initialize all the virtual base class in the inheritance
hierarchy. To make such a class simply create a empty class
with a private constructor and mark the class to be made
non derivable as the friend of that class. Now simply
public virtually derive the non derivable with the empty
class. Below is the example code:
class UnDerivable;
class dummy{
private:
dummy(){}
friend class UnDerivable;
};
class UnDerivable: virtual public dummy
{
};
//try deriving fro the underivable class
class deriveUnderivable:public UnDerivable
{
};
int main()
{
UnDerivable ud;
deriveUnderivable uud; //will give an error
return 0;
}
