C ++ 11 Thread Library One of the most important features of c ++ 11 is its support for multithreading. However, the 5th section of c ++ primer does not cover this part, which is a pity. I learned about the thread library on the Internet. These are

Design Mode note status mode State   // State mode ---- object behavior mode   /* 1: Intention: Allows an object to change its behavior when its internal state changes. The object seems to have modified its class. 2: alias: Status object (Objects

[C ++ basics 05] youyuan function and youyuan class, 05 yuan class Youyuan is a common function or class defined outside the class, but it needs to be described in the class body. In order to distinguish it from the member functions of the class,

For a long time, I have not systematically read the 23 design models in one breath, and I will always check them online. I had no time to think about these 23 design models, so I was always unable to understand the MFC framework, and it was really

This article summarizes and excerpts a text query program, a big example in C ++ primer. The main purpose is to learn the programming specifications of masters. Program Requirements: read any text file specified by the user, and then allow the user

C ++ from scratch (11) -- Knowledge about classes Due to space limitations, this article is the next article in "C ++ from (11)", discussing polymorphism and other issues. Virtual meanings The middle part of this article has already introduced the

See some articles, do a VC, CB, GCC General Property Declaration macro function, by CB and Devcpp test pass, release version of efficiency without loss. I don't know what the C + + committee is eating, doing that standard library all day, but

Constructors are the key to implementing inheritance, when a subclass object is constructed, the constructor of the parent class is called first, and its own constructor is called.#include using namespace std;template class a{public :

Seventh ChapterFunctions are declared before they are called.New and delete can be used to allocate memory and release. Although malloc and free are also reserved, it is not recommended.The general format used by the delete operator is the delete []

1.C What are the main differences from C + +? Answer: 1. The C + + language includes the procedural language part and the class part, the procedural language part and C do not have the essential difference, the class part is not in the C language,

1. Three basic concepts of object-oriented programming: Data abstraction (Class), Inheritance (class inheritance), and dynamic binding (the runtime determines whether a base class function or a derived class function is used). The key idea of object-

In the study of this part of some places do not understand, some are excerpted from the web materials.1, overloaded operators have two forms, that is, overloading the member functions of the class and overloading the friend function for the class.2,

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

Relative to Java, Friend is a special element of C + +, a lot of textbooks on the relatively small introduction, so beginners often can not grasp quickly, this article summed up the use of friends and some places of attention for reference. Hope to

(1) Concept (1) Why to make Ufida yuan Reduce system overhead and improve efficiency when implementing data sharing between classes. If a function in Class A accesses a member of Class B (for example, an implementation of a smart pointer Class),

Object serialization is the most frequently seen scenario in a project, so there are a number of libraries that implement this functionality, such as thrift, PROTOBUF, Avro, but I think these libraries are too heavy because they also provide RPC

Turn from: http://blog.csdn.net/lmsnju/article/details/4734840 This paper mainly discusses a common technology of C + + programming--Smart pointer (smart pointer), which includes reference count (reference count) and handle class (handle Class). If

Packages (Package)The role of the package keyword package and import When writing a Java source file, this file is often referred to as a compilation unit . Each compilation unit must have a suffix name . java. In a compilation unit, you can
