它存在的意义是什么？ 每个初学编程的人第一个程序都是hello world，在每次接触到新的编程语言时，还会再写hello world吗？ 你觉得它存在的. I've once been told that it was the first sentence. Other smalltalk systems such as pharo or cuis.

为什么写程序都从hello world开始？ 为啥总是 hello world 奇怪 不论学习什么编程语言 总是从 hello world 开始 为什么呢？ 起源 这一切都要从头说起 linux 操作系统的老祖宗 unix 和 unix 对应的编程语. Hello world! is the most commonly used example i can think of, yet i don't really know where it came from. Hello world 是用来测试 c 语言的编译器的程序之一。 这个程序在 1974 年被 kernighan 写进了贝尔实验室内部的 c 语言教程里，并最终于 1978 年由 kernighan 和 ritchie 在 the c programming.
I've always wondered where this sentence came from and where was it first used.
First time i see somebody asking a question about how to implement hello world in a language. Was it used by s. Makes you wonder what that says about the language if that's causing people trouble. Change 'hello world' to something like 'hello' , string space , 'world' to convince yourself that this actually evaluates a smalltalk expression.
因为介绍某种语言的教材往往在第一章就会给出hello world的例子。 至于为什么是hello world，据说最早出现于1972年，贝尔实验室成员布莱恩·柯林汉撰写的内部技术文件《a tutorial introduction to the. ' hello, world ' is usually the first example for any programming language.
