You are welcome to repost the post, but please mark the author as "nine days Yan Ling". Of course, the link to this post is better. Without knowing it, I have written six lectures. It is true that this learning can force me to really debug the code

This is an article I saw on csdn.The lecture is not bad. I will post it for you to see.1. When passing a pointer, we can use the pointer to modify the content it points externally. However, it is impossible to modify the object pointed to by the

You may have been using VC to develop software, but you may not be familiar with this compiler. There are many reasons. In most cases, we only "use" it, instead of "Understanding" it. Because it is just a tool, we would rather focus more on the C ++

  1. Why should I add the extern "C" to call the function compiled by the C compiler in the C ++ program "?A: First, extern is a keyword in the C/C ++ language that indicates the range of the function and global variable. This keyword tells the

Const thinking 1. What is const?A common type is a type described by the Type modifier Const. The values of variables or objects of a common type cannot be updated. (Of course, we can steal the bar for updating :) 2. Why is const introduced?The

It is nearly two years after graduation. From the very beginning of the program writing, there are only a handful of companies interviewed. The old man said that he would like to expand himself in the battle. It seems that my experience is far from

In openvpn, a good memory management solution is based on the linked list. The implementation of this solution uses a gc_arena structure, the function of this struct is to collect all dynamically allocated memory blocks and release them in one place.

In programming, especially in a large team, it is extremely important to follow a unified programming specification. Develop a source code writing standard for all developers and a naming standard for programs and files so that they are programmed

Introduction: This article introduces two new features of the C ++ 11 standard: defaulted and deleted functions. For the defaulted function, the compiler automatically generates the default Function Definition body for it to achieve higher code

C ++ is such a complex language that can be divided into four major parts:1. C language: for example, built-in data types, arrays, pointers, preprocessing, and statements are all from C.2. Object-oriented C ++: Class, constructor, destructor,

If a class is not associated with a specific thing, but only expresses an abstract concept, it is only used as a base class of its derived class. Such a class is an abstract class, when declaring a method in an abstract class, adding abstract is an
