Shared_ptr Header file: "Boost/shared_ptr.hpp" Almost all programs with slightly complex points require some form of reference counting smart pointers. These smart pointers eliminate the need to write complex logic to control the lifetime of objects

It consists of six parts: scoped_ptr, scoped_array, shared_ptr, shared_array, weak_ptr, and intrusive_ptr. Scoped_ptr is similar to STD: auto_ptr, but its ownership is more strict. Once obtained, it cannot be transferred. 1 Namespace Boost { 2
