Hello, world
Where every programmer starts, in two lines you can wear.
Brian Kernighan made this the first program people still teach. The 1978 C book made it famous.

The bars are Brian Kernighan's program, not a page from the 1978 book. A lawyer cleared this listing. The book page is not printed on the object.
Brian Kernighan wrote this program in a 1974 Bell Labs memo, and the 1978 C book turned it into the greeting that opens almost every programmer's first day. It prints two words and stops.
The bars are a main, a call, a string, and the braces around them. The lines are thick because the program is short, and the string reads green. It is the smallest piece here, and the one most people have already typed.
