tree copy constructor...

[Paul McKenzie]

Anyway im posting this for future referance because i already figured it out. The problem was with the way i was dealing with node parents...

You still didn't code an assignment operator. If not, your program will not be able to do this correctly:

int main()
{
   TreeNode<int> T1;
   TreeNode<int> T2;

   T1 = T2;   // no good
}

When coding a copy constructor, it always goes with an assignment operator. The reason why is that C++ programmers who expect this to work:

TreeNode<int> T1;
TreeNode<int> T2 = T1; // copy constructor called

Also expect this to work:

   TreeNode<int> T1;
   TreeNode<int> T2;
   T1 = T2;

since both are natural means of assigning and constructing objects.
