One advantage of boost::shared_ptr p1; over shared_ptr> p2; is that the former gives you p1[index] which is slightly nicer than (*p2)[index]. In the case of both, the size N is already known at compile time anyway since it is part of the type.

Why not simply use vector or shared_ptr< vector<...> >?

If what he really wants is a std::vector<T>, this is a good alternative. If not, he pays for a few things you may not use: e.g. one additional allocation compared to boost::shared_ptr. Glen
