Abstract
Brian Kernighan, a computer scientist, wrote the first "Hello, World!" program in 1972 for the language B to be used internally at Bell Labs. Brian wrote a manual titled A Tutorial Introduction to the Language B to demonstrate how to use B's language. From there, this popular text spread quickly. It was used in a Bell Laboratories memo in 1974, as well as The C Programming Language in 1978. "Hello, World!" remains popular to this day. It became a standard for new programmers for their first program. This particular piece of code proves your code syntax, compiles, and executes to consistently produce the desired output. "Hello, World!" offers the code in more than 60 programming languages.
