Hello World!各类编程.doc

作为所有编程语言的起始阶段，HELLO WORLD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！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：AKA 控制台:ABC语言的Hello World程序WHILE (1=1) : WRITE Hello World Ada语言的Hello World程序with Ada.Text_Io; use Ada.Text_Io; procedure Hello is begin Put_Line (Hello, world!); end Hello;AmigaE语言的Hello World程序PROC main() WriteF(Hello, World!)
