Introduction: What is serialization? To put it simply, serialization is the process of converting the state of an object instance to a format that can be maintained or transmitted. In contrast to serialization, deserialization is used to

IntroductionRecently, I am working on a Web Crawler. In order to better utilize the Web crawling capability, I need to use Asynchronous HTTP. DNS resolution and download must be asynchronous. This component is implemented based on WinHTTP. If you

I recently read the memcached source code and think that its libevent + multi-thread Server Model (Multi-reactor) is really good. I encapsulated this model into a C ++ class, according to my simple test, the efficiency of this model is really good.

This article describes how to process files in an object-oriented way. However, the disadvantage is that it depends on the operating system and environment. The SDK described later depends on Windows, and cstdiofile depends on the MFC framework

Before designing a class, you must first determine whether the object instantiated by the class is the value semantics or the reference semantics. Value SemanticsIt is generally used for non-dedicated resource objects,Indicates that the object can

Object-oriented design defects In this section, we will analyze which oo principles are violated by iostream design. We know that the public inheritance in the object-oriented model must meet the liskov replacement principle. (See article 32 of

Because the Package concept does not exist, the protected of C ++ is different from that of protected in Java. protected in Java is not only accessible to sub-objects, but also to other parts of the package, it can also be displayed through

The question is too big to be written. It is enough to write a book. I am a person from the past, and I will share my experience with you, hoping that new people will be able to avoid detours. The situation varies with everyone. The descriptions

The format function in C ++ builder serves the same purpose as that in Delphi. But the only difference is the parameter. Because delphi supports the "on Parameters" and dynamic array features, the format in Delphi only has two parameters, the latter
