If you need to reprint it, please indicate the source The offsetof method provided by Linux is to get the offset byte in this struct of a member field in a struct, which is implemented in the user State. Example of implementation in user State: Get the value of a field in the Child structure of a struct. Assume that you only know the type of the large structure, the name of the child structure, and the name of a certain field in the Child knot. Idea

Permutation and combination is a common mathematical problem, this paper describes the method of C # Implementation of permutation combination algorithm in the form of a complete example. Share it for everyone's reference. Here's how:First, the mathematical arrangement of the combination, can be expressed as: permutation P (n,r)In fact, the implementation of the arrangement, the combination is realized, the

character sets. Match any character not included. For example, '[^ abc]' can match 'p' in "plain '.[A-z] character range. Matches any character in the specified range. For example, '[a-z]' can match any lowercase letter in the range of 'A' to 'Z.[^ A-z] negative character range. Matches any character that is not within the specified range. For example, '[^ a-z]'

C-language and assembly language mutual invocation principle and example 1. PrincipleIn fact, whether it is the C language or assembly language want to do is the final compile link to become a binary file.It is important to make sure that compilation and linking are two steps, and the resulting file format is not the same.Compile the generated file is a certain f

I. Overview Vector is part of the C ++ standard template library. It is a versatile template class and function library that can operate on multiple data structures and algorithms. Vector is a container that can store various types of objects. Simply put, vector is a dynamic array that can store any type and dynamically change the size. For example: // C Language

I have never understood the use of the common Body Union when I was studying C in school. After work only to find some of its magical, the proportion is as follows:1. To make it easier to read the code.For example, to write a 3 * 3 matrix, you can write:[ Note: The following is marked with the red part of the place is later added, thank you yrqing718 reminder! ] struct Matrix { Union { struct

First, explain the network communication using the socket interface in principle. Here we use the most common C/S mode as an example. First, the server has a process (or multiple processes) wait for the customer to connect to the specified port, and the service program waits for the customer's connection information. Once connected, the data can be transmitted according to the designed data exchange method

My example is to prove the good cross-language features of protocol buffer. The example consists of twoProgramA c ++ program is responsible for serializing the object user to a file. The other is the Java program, which is responsible for deserializing from files into user objects. The following figure shows the relationship between two programs and Protocol

I personally understand the value passing, address passing, and reference passing in C language.Through an example: Swap (Swap the value of two integer variables) to express!1#include 2 voidSWAP1 (intAint*b);3 voidSWAP2 (int A,intb);4 voidSWAP3 (intAint*b);5 6 voidMain () {7printf"Hello world!\n");8 intA =3;9 intb =4;Tenprintf"bef Swap, add of a =%d\n",a); Oneprintf"aft Swap, val of a =%d\n", a); A

thread.Multithreaded Programming Example 1:C + + code #include #include Using namespace std; DWORD WINAPI Fun (lpvoid lpparamter) { While (1) {cout' fun display! ' } int main () { HANDLE hthread = CreateThread (null, 0, fun, NULL, 0, NULL); CloseHandle (Hthread); While (1) {cout"main display!" return 0; } We can see that the main thread (main function) and our own

GDI + provides five paint brushes, including solidbrush (solid color brush), hatchbrush (shadow brush), texturebrush (texture brush), lineargradientbrush (gradient brush), and pathgradientbrush (path brush, in the C language version of GDI +, the painting brush methods are prefixed with the original C ++ class name. The lineargradientbrush and pathgradientbrush are simplified to linebrush and pathbrush, res

For example, find compelling authoritative C + + intermediate malloc with newProblem: Many people know that malloc and new are used to apply for space, and that space is derived from the heap. But in C + + very few use malloc to apply for space, why? The following small series are illustrated in a very convincing

In this paper, a simple example to illustrate the implementation of the C # Strategy model, shared for everyone to reference. The implementation method is as follows:In general, when there are multiple implementations of an action, you might consider using a policy mode when you need to choose a method to perform the action according to different circumstances.Abstract the action into an interface, such as

This article is a simple example of the C # object is a null mode (Null object pattern), shared for everyone to reference. The implementation method is as follows:The so-called "object is null mode", is to ask the developer to consider the object is null, and design the response in this case.With the front ""In the example of the article, in our client program on

An integer itself plus one can be written like this: A+=1; It is equivalent to a=a+1;. But there is also a simpler way of writing in C, which is a++ or ++a; This type of writing is called self addition or self amplification; it's clear that you add one to yourself. Correspondingly, there are a--and--a, called the self reduction, which means to reduce one. + + and--are called self-increment and self subtraction operators, respectively. Examples o

configuration. Note: Grouping names are case-sensitive and must be consistent with the defined grouping names. 3. Read configuration After you have defined the configuration file, you can use the C method provided by the system (if you feel strange, you can help memory by using the Config word) to read the existing configuration C (' parameter name ')//get the parameter value that has been set

, so in order to avoid this situation, the uniform subscript to lowercase (of course, uppercase is also possible), Because the array in the config file is only a maximum of two dimensions, it's enough to lower the subscript of a one-dimensional array. 4. How to use in actual combat? PHP is very handy for arrays, so the configuration file is typically written in a configuration file, returned as an array The General format is: Copy Code code as follows: config.php Write th

The example of the C #. NET implementation of the currency conversions described in this article mainly uses String.Format and CultureInfo to convert. Share it for everyone's reference. Here's how:The main implementation code is as follows:I hope this article is helpful to everyone's C # program designIn addition to the Declaration,Running GuestArticles are origi
