Thread: Passing member variable as default arg to member function

Is it possible to pass a member variable as the default argument to a function of the same class? I want to reverse a linked list using recursion, but I need to pass the head of the linked list the first time that the function is called.

Something like this but that actually compiles:

Code:

class Linked_List
{
private:
	Tree_Node *head;
public:
	void reverse(Tree_Node *next = head);
};

No, but you can do this instead:

Code:

void reverse(Tree_Node *next = 0)
{
    if(next == 0)
        next = head;
// ...etc...
}

But a better approach is probably just to write a separate function:

Code:

void reverse(Tree_Node *next)
{
// ...etc...
}

inline void reverse(void)
{
    reverse(head);
}
