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). Vector Operation:
■ Vector deletion and insertion element performance:
◆ Install or remove elements at the end of the container
◆ Capacity should be large at the beginning
◆ Calling multiple elements at a time
Try/Catch/ThrowWhich methods can be used to improve software quality?
ReplaceTry/Catch/ThrowThe common practice is to return a response code (sometimes called an error code), for example,Printf (),Scanf ()AndMalloc ()It works like this: the caller
I. general usage instructionsIn C #, all classes inherited from objects have the tostring () method. Without special declarations, classes in C # are inherited from objects by default, therefore, there are tostring () methods, while convert.
