The ‘final’ class in C++

The ‘final’ class in C++

Suppose you need to prevent the derivation of a class?like in the final classes of Java. Simply make the constructor of the class private. Here’s an example:

class final{private:	final(){} ;public:	static final* CreateInstance()	{		return (new final()) ;	}} ;/* UNCOMMENTing will give error because we've declared constructor of final class as privateclass derived : public final{public:	derived()	{	}} ;*/void main(){	final *f ;	f = final::CreateInstance() ;}
