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

The technology of the smart switch that appears on the market is

http://blog.csdn.net/baliguan163/article/details/11720835 recommendation 34: Manage objects created by new with smart pointers We have repeatedly repeated in the previous recommendations: memory leaks are a big problem. Many techniques have been developed to address this problem, such as garbage Collection (garbage collection), smart pointer (smart pointers), and

Sorry, it has never been updated since the last smart UI introduction series. We planned to complete the smart UI website, API, and demo in one week, only when the results are written can we find that there is not much content.

1. Problems with traditional pointersThere are many problems with traditional pointers, such as the life cycle of the object to which the pointer is pointing, the suspend reference (dangling references), and the memory leaks.The following is a procedure for using a traditional pointervoid Foo() { int *iPtr = new int[5]; // manipulate the memory block ... ... ... delete[] iPtr;}The above code will run normally and the memory will be properly freed, but using pointers often happe

Smart pointers address the issue of resource lifetime management (especially dynamically allocated objects). Smart pointers are available in a variety of different styles. Most have a common key feature: automatic resource management. This feature may appear in different ways: such as the lifetime control of dynamically allocated objects, and the acquisition and release of resources (files, network Connecti

C ++ smart pointer management and smart pointer Management1. the programmer explicitly releases the memory For c ++ programmers, the most important thing is to manage the dynamically allocated memory. C ++ memory allocated on the heap requires the programmer to release the allocated memory. But sometimes the release of memory does not seem very easy, the following program Void func () {int * p = new int (0)
