The story of “hello world”

In the latter part of the 1970s, an eminent computer scientist named Brian Kernighan found himself engrossed in a groundbreaking endeavor. He was a valuable member of a distinguished team working on a revolutionary programming language titled “B” at the renowned Bell Labs, a language that would eventually metamorphose into the widely adopted “C.”

During the development process of the B language, the team encountered the need for a simple and concise program to thoroughly test the language’s functionality. They sought an uncomplicated method to showcase their language’s capability in handling basic input and output operations. It was then that Brian Kernighan, in collaboration with his esteemed colleague Dennis Ritchie, conceived a truly ingenious notion.

Their plan involved crafting a small yet effective program that would gracefully display the phrase “hello, world” on the computer screen. The choice of this particular phrase was deliberately simple and hospitable, serving as a warm and friendly greeting from the computer to the programmer. It was meant to be an unthreatening and easily comprehensible example, specifically tailored for those embarking on their journey to learn the art of coding.
