Constructing a tree using Boost's shared_ptr and weak_ptr?

You should not use a weak pointer for the node like this. A weak pointer means that the object may be deleted even if there are still weak pointers available for the object, if no other weak pointers to it exists.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
