Clause 3: select a smart pointer based on functions and implementation principlesThere are many types of smart pointers. The implementation principles can be divided into two categories: ownership-based transfer and reference-based counting. The built-in std: auto_ptr in C ++ is a smart pointer based on ownership transfer. Shared_ptr In the Boost library is a
