Exercise in Stroutstrup book

Question

"Find an example where it would make sense to use a name in its own initializer."

I believe the author is referring to an initialization like this :

int x = x;

Answer 1

Stroustrup has written 4 books. Which one are you referring to?

Answer 2

I tried the example given in

http://stackoverflow.com/questions/1180805/tcpl-5-9-9-c-where-would-it-make-sense-to-use-a-name-in-its-own-initializer

as the answer, but it didn't compile (C2065 : 'n' : undeclared identifier)

class Node
{
     public:
     Node(Node* next): next(next){}

     private:
     Node* next;
};

int

 

 

main()
{
    Node n(&n);
}

Any thoughts ?
