auto_ptr v2=v1;
then v1 will not hold the pointer to the resource.
for share_ptr, you can have several objects to manage the same resource

std::auto_ptr is not a reference counted smart pointer. It does NOT have
ownership, i.e, when a std::auto_ptr is assigned to another one, its
ownership is transferred. As a result, it can NOT be used in standard
containers. | d********t
