1. Backgroundmany times to learn C language has been unable to step into the C language gate, each time in the C language of those system call library functions and so on, but only, Linux system calls need us to remember some irregular structure and some uppercase macro definition and there is a function of various forms such as print fprintf sprintf and so on, looks very uncomfortable, writing things to really very silent. Write what you want, write what you want to do to make the error-handlin

15th. Object-Oriented Programming OOP (Object-oriented programming)Object-oriented programming is based on three basic concepts: Data Abstraction , inheritance , and dynamic binding 。 In C + +, you use classes for data abstraction, and class derivation to inherit from one class from another: Derived classes inherit members of the base class. Dynamic binding enabl

First of all, object-oriented programming (OOP), object-oriented programming mainly for the business process of the entity and its attributes to the abstract encapsulation, to obtain a clearer and more efficient logical unit division. Mainly in order to realize the reusability of programming, flexibility and scalability. Some of its features are encapsulation, in

Through the discussion of the previous article, I think my friends have a general understanding of "interface Programming". So in this article, we use an example to give you a visual impression of this important programming idea. In order to fully consider the beginner, so this example is very simple, I hope you master forgive me.The question is raised definition: Now we are going to develop an applic

As a popular course in primary and secondary schools, scratch is different from the traditional character code. There is no English threshold for Graphic programming. By dragging blocks, children can intuitively understand the operating principle behind the code, without knowing it, you can master programming algorithms. Through simulated cartoon project-based teaching such as animations that students love,

Because of PHP's characteristics, causing a lot of PHP people only understand the site development-related knowledge, but now with Swoole and workman this extension, so want to ask about this kind of "UNIX system programming, network communication programming, asynchronous Io, multithreading" knowledge, if you want to learn, From the PHP Programmer's Point of view, give a learning route, thank you Reply

A recently maintained network server encountered performance problems, so it made major changes to the original program framework. Most of the changes are the thread working mode and data transmission mode. The final result is to change the lock usage mode. After some improvement, the GMB Nic can basically work at full speed. After the performance was up to standard, I was wondering if I could use a more lightweight lock or remove the lock. For this reason, I searched some research results and m

Object-Oriented Programming (Chapter Summary), object-oriented programming chapter1. Object-oriented has three main features: encapsulation, inheritance, and polymorphism.2. If a class drug settings inherit, you must specify NOTFINAL; otherwise, this class cannot be inherited.3. to sort the queried data, you can use MAP or ORDER to define a function.4. In a class, the default CONSTRUCTOR needs to pass all t

Examples of javascript functional programming and javascript programming This example describes javascript functional programming. Share it with you for your reference.

Pair programming is a technique. It requires practice and is not easy for everyone to start. Pair programming is an extremely important skill in XP, so it is worth cultivating this habit to take advantage of it. The system structure is in inquiry, in metaphor, In the first iteration and elsewhere. XP processes the architecture through the following mechanisms: inquiry, metaphor, first iteration, minor ver

Introduction: In the previous topic, a friend left me a message about P2P-related content. First of all, I am not a big fan of C # network programming. Because of the relationship between capabilities, I can only share some of my learning processes with my understanding of some of my learning processes. Next I will go to the topic-peer-to-peer programming. I. Introduction to P2P First of all, the w
