The implementation of Yang Hui Triangle in C
#Problem description: Create a program to find triangles. The program prompts the user to enter data and then displays the pattern of Yang Hui's triangle.
// Input description: Yang Hui’s triangle length, representing numerical value #
using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace ConsoleApplication2 { class Program { static void Main(string[] args) { int length = 0;//杨辉三角形的长度 Console.Write("输入杨辉三角长度:"); length = Convert.ToInt32(Console.ReadLine());//指定杨辉三角形的长度 int[][] a = new int[length][];//二维数组 for (int i = 0; i < a.Length; i++) a[i] = new int[i + 1];//遍历,赋值增量 for (int j = 0; j < a.Length; j++) { a[j][0] = 1; //把第1列的元素都赋1 a[j][j] = 1; //把每1列最右边的元素都赋1 for (int m = 1; m < a[j].Length - 1; m++) a[j][m] = a[j - 1][m - 1] + a[j - 1][m];//其余元素的值由杨辉公式计算 } for (int i = 0; i < a.Length; i++) //遍历数组输出杨辉三角形 { for (int j = 0; j < a[i].Length; j++) Console.Write("{0}\t", a[i][j]); Console.Write("\n"); } Console.Read(); } } }

The future trends of C#.NET are mainly focused on three aspects: cloud computing, microservices, AI and machine learning integration, and cross-platform development. 1) Cloud computing and microservices: C#.NET optimizes cloud environment performance through the Azure platform and supports the construction of an efficient microservice architecture. 2) Integration of AI and machine learning: With the help of the ML.NET library, C# developers can embed machine learning models in their applications to promote the development of intelligent applications. 3) Cross-platform development: Through .NETCore and .NET5, C# applications can run on Windows, Linux and macOS, expanding the deployment scope.

The latest developments and best practices in C#.NET development include: 1. Asynchronous programming improves application responsiveness, and simplifies non-blocking code using async and await keywords; 2. LINQ provides powerful query functions, efficiently manipulating data through delayed execution and expression trees; 3. Performance optimization suggestions include using asynchronous programming, optimizing LINQ queries, rationally managing memory, improving code readability and maintenance, and writing unit tests.

How to build applications using .NET? Building applications using .NET can be achieved through the following steps: 1) Understand the basics of .NET, including C# language and cross-platform development support; 2) Learn core concepts such as components and working principles of the .NET ecosystem; 3) Master basic and advanced usage, from simple console applications to complex WebAPIs and database operations; 4) Be familiar with common errors and debugging techniques, such as configuration and database connection issues; 5) Application performance optimization and best practices, such as asynchronous programming and caching.

C# is widely used in enterprise-level applications, game development, mobile applications and web development. 1) In enterprise-level applications, C# is often used for ASP.NETCore to develop WebAPI. 2) In game development, C# is combined with the Unity engine to realize role control and other functions. 3) C# supports polymorphism and asynchronous programming to improve code flexibility and application performance.

C# and .NET are suitable for web, desktop and mobile development. 1) In web development, ASP.NETCore supports cross-platform development. 2) Desktop development uses WPF and WinForms, which are suitable for different needs. 3) Mobile development realizes cross-platform applications through Xamarin.

The C#.NET ecosystem provides rich frameworks and libraries to help developers build applications efficiently. 1.ASP.NETCore is used to build high-performance web applications, 2.EntityFrameworkCore is used for database operations. By understanding the use and best practices of these tools, developers can improve the quality and performance of their applications.

How to deploy a C# .NET app to Azure or AWS? The answer is to use AzureAppService and AWSElasticBeanstalk. 1. On Azure, automate deployment using AzureAppService and AzurePipelines. 2. On AWS, use Amazon ElasticBeanstalk and AWSLambda to implement deployment and serverless compute.

The combination of C# and .NET provides developers with a powerful programming environment. 1) C# supports polymorphism and asynchronous programming, 2) .NET provides cross-platform capabilities and concurrent processing mechanisms, which makes them widely used in desktop, web and mobile application development.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
