Answer 2

Option d): < autoptr>

< autoptr> header file should we include for using std::auto.ptr

• An object obtained using a new expression is managed by the smart pointer auto ptr, which also deletes the object when auto ptr is destroyed.
• Because auto ptr's copy function Object() { [native code] } does not adhere to container CopyConstructible's requirements, it cannot be utilized in STL containers. Because unique ptr does not have a copy function Object() { [native code] }, containers must utilize other techniques.
• Although not atomic-free, this method of passing an object from one thread to another is entirely threadsafe and lock-free. A queue is usually the best option if you have a lot of these items, but occasionally that's a little too heavyweight for your purposes.
