فهرست مثالهای برنامه Hello World
یک برنامه Hello World یک برنامهٔ رایانهای ساده است که جمله «Hello, world!» را در صفحه نمایش چاپ میکند. معمولاً سادهترین برنامهٔ ممکنی است که میتوان در زبانهای برنامهنویسی مختلف نوشت و یک عمل سنتی است که بسیاری از برنامهنویسان که قصد آموزش یک زبان برنامهنویسی را دارند، توصیه به نوشتن آن میکنند که اولین قدم در یادگیری آن زبان برنامهنویسی است. بیشتر از این برنامه برای مقایسه نحو دو زبان مختلف استفاده میشود. در زیر فهرستی از برنامههای Hello World مرسوم در ۹۱ زبان برنامه نویسی آمده است.
