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。
