A "Hello, world!" program is a trivial program which outputs a static string of text[note 1], usually
Hello, world!
This program is often the first one written in a new esoteric programming language, to demonstrate output. It is a popular problem.
The program comes from the first example program in the classic K&R C manual. Note that the K&R version was in all lowercase and lacked an exclamation mark.

Notes
- ↑ If the static string is not "Hello world", then the problem may be more often called "kolmogorov complexity" problem.
