hello world作為所有編程語言的起始階段，占據著無法改變的地位，所有中/英/法/德/美……版本的編程教材中，hello world總是作為第一個TEST記錄于書本之中，所有的編程第一步就在于此了！經典之中的經典！
hello world！
"Hello, world"程序是指在計算機屏幕上輸出Hello, world這行字符串的計算機程序，“hello, world”的中文意思是“世界，你好”。這個例程在Brian Kernighan和Dennis M. Ritchie合著的The C Programming Language中被使用而廣泛流行。因為它的簡潔、實用，并包含了一個程序所應具有的一切，因此為后來的編程類圖書的作者提供了范例，一直待續到今。
