百科名片

C和C++“hello world”程序

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！目录

简介

这个例程是从Kernighan & Ritchie 合著的《The C Programme Language》开始有的，因为它的简洁，实用，并包含了一个程序所应具有的一切，因此为后来的些类书的作者提供了范例，一直待续到今。

我们刚开始接触计算机语言大多从Hello world 开始，下面是各种语言的Hello world program：

as400的RPGLE语言： D Vc_Hello s 100A

C Eval Vc_Hello = 'Hello World!' C DSPLY Vc_Hello

Java applet语言的Hello World程序

Java applets work in conjunction with HTML files. HelloWorld Program says: import java.applet.*; import java.awt.*;

public class HelloWorld extends Applet { public void paint(Graphics g) { g.drawString(\ } }

JavaScript, aka ECMAScript

JavaScript is a scripting language used in HTML files. To demo this program Cut and Paste the following code into any HTML file. onclick=\

An easier method uses JavaScript implicitly, calling the reserved alert function. Cut and paste the following line inside the .... HTML tags. Hello World Example

An even easier method involves using popular browsers' support for the virtual 'javascript' protocol to execute JavaScript code. Enter the following as an Internet address (usually by pasting into the address box): javascript:alert('Hello, world!') 文档格式:

ASCII语言的Hello World程序

The following sequence of characters, expressed in hexadecimal notation (with carriage return and newline characters at end of sequence): 48 65 6C 6C 6F 2C 20 77 6F 72 6C 64 21 0D 0A
