    hello world程序集锦

    hello world作为所有编程语言的起始阶段,占据着无法改变的地位,所有中/英/法/德/美……版本的编程教材中,hello world总是作为第一个TEST记录于书本之中,所有的编程第一步就在于此了!经典之中的经典!

    hello world!

    "Hello, world"程序是指在计算机屏幕上输出Hello, world这行字符串的计算机程序,“hello, world”的中文意思是“世界,你好”。这个例程在Brian Kernighan和Dennis M. Ritchie合著的The C Programming Language中被使用而广泛流行。因为它的简洁、实用,并包含了一个程序所应具有的一切,因此为后来的编程类图书的作者提供了范例,一直待续到今。

    HelloWorld Program says:
    applet code="HelloWorld.class" width="600" height="100">
    /applet>
    /body>
    /html>
    

    Java代码:

    import java.applet.*;
    import java.awt.*;
    
    public class HelloWorld extends Applet 
    {
     public void paint(Graphics g) 
     {
      g.drawString("Hello, world!", 100, 50);
     }
    }
    
    

    JavaScript

    JavaScript是一种脚本语言。最广泛用于HTML文件中,也可以用在其它宿主环境下,比如Microsoft Windows 脚本宿主(WSH)和一些Web服务环境。

    用于HTML中:

    alert("Hello, World!");
    //或者
    document.write("Hello, World!");
    

    用于WSH中:

    WScript.Echo("Hello, World!");
    

    PostScript

    PostScript是一种专门用来创建图像的语言,常用于打印机。
