A smart pointer is actually a class, which encapsulates a pointer. What is its usefulness?Pointer and memory
When it comes to pointers, memory is involved.Memory is allocated in the stack. The system is responsible for releasing the memory after it is used up.. If it is a custom type, your destructor will be automatically called.
HoweverHeap memory is allocated, that is, with malloc or new. It can only be automatically and manually released using free

Android defines two types of smart pointers: strong pointer Sp (strong pointer) and weak pointer (weak pointer ). In fact, it is more suitable for strong references and weak references. Strong pointers share the same concept as smart pointers in general sense. The reference count is used to record how many users are using an object. If all users give up referencing this object, the object will be automatica
Identity authentication, known as "Authentication" or "Identity Authentication", refers to the process of confirming the identity of an operator in a real application, which determines whether the user has access to and use of a resource, prevents an attacker from impersonating a legitimate user for access to resources, guarantees the security of the system and data, and authorizes the legitimate interests of the visitor.
The proposed scheme is based on the assumption that the user wants to log

1. Introduction to Smart Client software factory
Smart Client software factory is a software factory series software framework of the Microsoft patterns practice project team. It is used to help developers build MVP-based desktops.Program(Winform), of course, this desktop program is a so-called Smart Client program that Microsoft has been vigorously promoting )
The use of smart pointers: in C + +, using normal pointers is prone to the problem of heap memory leaks, that is, the programmer will forget to release, and two releases, the program is abnormal when the memory leaks and other issues, and use smart pointers to better manage heap memory. Note that here the smart pointer is a class rather than a real pointer, just
Smart pointers (smart pointer) are classes that store pointers to dynamically allocated (heap) objects for lifetime control, ensuring that dynamically allocated objects are automatically and correctly destroyed, preventing memory leaks. A common implementation of this technique is to use reference counting (reference count). A smart pointer class relates a counte
What auto_ptr (commonly known as smart pointers) in C + + does is like a normal pointer, but when it allocates memory dynamically, it no longer needs to consider cleanup issues. When its lifetime is over, the system automatically cleans up the memory it points to.In fact, Auto_ptr is a template class (note essentially a class). Primarily addresses memory leak issues.Principle: In fact, is RAII, in the construction of the time to obtain resources, in t

Why smart pointers are present
With smart pointers, the application of memory is implemented within the interface and limited, the release of memory to the work of the smart pointer.

Brief introductionIn order to solve the problem of memory leak caused by C + + program, C++11 provides 3 kinds of smart pointers: Std::unique_prt, Std::shared_ptr, Std::weak_ptr. The principle of smart pointers is to store a well-applied memory address inside the smart pointer structure, and then save the smart pointer
