Smart pointers in container like std::vector?

Question

I am learning about smart pointers (std::auto_ptr) and just read here and here that smart pointers (std::auto_ptr) should not be put in containers

Answer 1

For classes that have an auto ptr data member, I always have a clone method that returns a new auto ptr. I then implement an assignment method and copy constructor that call the clone method (and never the default assignment operator of auto ptr). This way you can safely use the class in STL containers.
