Before starting this article, let's summarize the previous content:1. The smart pointer uses the RAII mechanism to initialize the resources when the object is constructed, and to clean up and Shanwei the resources when the objects are reconstructed.2

1. Display interface and run-time polymorphismThe world of object-oriented programming revolves around explicit interfaces and run-time polymorphism. For example, consider the following class (a meaningless Class),1 classWidget {2 Public:3 widgets (

Chapter One, function pointersfunction Pointer : is a pointer to the function of the variable, at C compile, each function has an entry address, then this function pointer to this functions point to this address.function pointers are used in large,

What's the function of return? What does return 0 mean?1: Stop execution, jump directly to the calling function there, the following statement does not execute (this can be understood). To give a very simple example1#include 2 intAddintAintb)3 {4

function : A collection of lines of code that is written to perform certain functions. Can be called by the same program or other program. function is the basic constituent unit of C language. The advantages of the function : The code is more
