Can a c++ class include itself as an member?

c++

Solution

No, because the object would be infinitely large (because every `Node` has as members two other `Node` objects, which each have as members two other `Node` objects, which each... well, you get the point).

You can, however, have a pointer to the class type as a member variable:

class Node {
    char *cargo;
    Node* left;   // I'm not a Node; I'm just a pointer to a Node
    Node* right;  // Same here
};

Problem

I'm trying to speed up a python routine by writing it in C++, then using it using ctypes or cython. I'm brand new to c++. I'm using Microsoft Visual C++ Express as it's free. I plan to implement an expression tree, and a method to evaluate it in postfix order. The problem I run into right away is: ``` class Node { char *cargo; Node left; Node right; }; ``` I can't declare `left` or `right` as `Node` types.
