auto_ptr是一个智能指针，通过新的管理对象和删除对象时，auto_ptr本身被破坏。它可用于动态分配的对象，拥有动态分配的对象传递到函数，从函数返回动态分配的对象提供异常安全.
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.

复制auto_ptr复制指针和所有权转移的目的地：auto_ptr拷贝构造函数和拷贝赋值修改自己的右手参数，并且不等于原来的“复制”。由于这些不寻常的拷贝语义，auto_ptr可能不会被放置在标准的容器。 std::unique_ptr优选这和其他用途.
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.
