object containing another object of the same class

[hamsterman]

Folowing code is suposed to hold any amount of information under one name. Yet it doesn't work. Can anyone tell me why?

class A
{
public:
	int x;
	A next;
}list;

Because you could theoretically use up an infinite amount of memory like that, and C++ can't count to infinity.

if you wanna make an int list next must be a pointer to an A object, not directly an A object.

That way anytime your system allocate an A object it must allocate another A object, then another and so on till your system finishes his memory.

I think you can try the following way if you know pointers:

class Node {
  public:
     int data;
     A * next;
};
