Recently, a TCP communication program was written, customizing a communication class TcpClient for clients to receive and send network messages asynchronously.A new network message event is defined in TcpClient:1 // receive new message events 2

The process of abstraction All things are objects. A program is a group of objects that are notified to each other by sending messages. Each object has its own storage area that is made up of other objects. Each object

1. Array : An array is a conforming data type consisting of a type name, an identifier, and a dimension, which specifies the type of element that is stored in the array, and the dimension specifies the number of elements in the array and the

This article is divided into two parts, first introduced in C language with random numbers related to the two functions Srand and Rand, after the introduction of the random library in C + +.1. Srand and Rand in the C language1) Implementation of the

In the book, C + + is divided into 4 sub-languages, looking forward to the chaotic C + + system for a simple comb, can only say that the purpose has been achieved, but so the appropriate inappropriate? I don't know....(1) C (c + + without Class)The

　　A const-defined constant is freed after its scope has been exceeded, and static constants defined by Statics do not release their storage space after the function executes.Static is expressed statically. Static member functions and static member

The string class provided by the C + + standard library does not provide a CString-like trim method, which is used to remove whitespace characters before and after a string. This functionality can be easily implemented using some of the methods of

first, the definition of segment treeFirst, the line tree is a completely binary tree. It is characterized by the following: Each node represents a line segment, or an interval. In fact, the root node of a segment tree represents the "whole"

When compiling the template, the compiler will resolve the name encountered in two phases, the first phase parsing does not depend on the name of the template parameter, the second phase resolution depends on the name of the template parameter, and

First, before learning to enumerate, listen to the advantages of enumerations.1. Enumerations can make the code clearer, allowing the use of descriptive names to represent integer values.2. Enumeration makes the code easier to maintain, helping to

The so-called static and non-static, it is in the declaration of a more use of a "static."So what is the difference between static and non-static?1, for non-static members, including methods, fields, properties. Called when it needs to be invoked
