How to define a class can't be inheritance? Like "final" Keyword in Java?

[player6]

It can be implement in C++? Thank u.

I think it's possible by making the ctor private, however you have to provide an alternative ctor, which may or may not suit your programming style.

class FinalClass
{
public:
	static FinalClass* CreateInstance() { return new FinalClass; }
private:
	FinalClass() {}
};

It can't be implemented in C++. The best way is to write a comment above a final class:

/*Do not inherit from this class*/
class my_final_class {/*...*/};

You might try some other magic, which makes the child class unusable somehow, but the above method works the best.
