auto_ptr является смарт-указатель, который управляет объектом получены с помощью новых и удаляет этот объект, когда auto_ptr сам будет уничтожен. Он может быть использован для обеспечения безопасности исключений для динамически размещаемых объектов, для передачи собственности на динамически выделенные объекты в функции и для возвращения динамически выделенные объекты из функций.
Original:
auto_ptr is a smart pointer that manages an object obtained via new and deletes that object when auto_ptr itself is destroyed. It may be used to provide exception safety for dynamically-allocated objects, for passing ownership of dynamically-allocated objects into functions and for returning dynamically-allocated objects from functions.

Копирование auto_ptr копирует указатель и передачи права собственности на назначение: строительство и копирования и назначение auto_ptr изменить свое право аргументы стороны, и "копия" не совпадает с оригиналом. Из-за этих необычных семантики копирования, auto_ptr не могут быть помещены в стандартные контейнеры. std::unique_ptr является предпочтительным для этой и других целей.
Original:
Copying an auto_ptr copies the pointer and transfers ownership to the destination: both copy construction and copy assignment of auto_ptr modify their right hand arguments, and the "copy" is not equal to the original. Because of these unusual copy semantics, auto_ptr may not be placed in standard containers. std::unique_ptr is preferred for this and other uses.
