c语言hello world代码(代码编程入门)

大家好，又见面了，我是你们的朋友全栈君。

using System;
using System.Collections.Generic;

public class MyClass
{ 
   
	
	struct Name{ 
   
		public string FirstName;
		public string LastName;
		
		public string GetName(){ 
   
			return  FirstName + "·" + LastName;

		public float z;
		
		public double Distance(){ 
   
			return Math.Sqrt(x*x+ y*y+ z*z);
		}
	}
	
	public static void RunSnippet()
	{ 
   
		Name myName;
		myName.FirstName = "Alexander";
		myName.LastName = "Azhar";
		System.Console.WriteLine("My name is " + myName.GetName());
		
		Vector3 point;
		System.Console.WriteLine("Please enter three points' position to calculate its distance: ");
		point.x = Convert.ToInt32(System.Console.ReadLine());
		point.y = Convert.ToInt32(System.Console.ReadLine());
		point.z = Convert.ToInt32(System.Console.ReadLine());
		System.Console.WriteLine("The Sqrt distance of the three points is "+point.Distance()+" .");
		
	}

		{

	private static void WL(object text, params object[] args)
	{ 
   
		Console.WriteLine(text.ToString(), args);	
	}

上面代码的结构一定要记住，因为结构比较好，所以和大家分享。
