Meaning of HELLO, WORLD

 
Computing Dictionary
 
 Definition: 

The canonical minimal test message in the c/unix universe or any of the minimal programs that emit this message. Traditionally, the first program a C coder writes in a new environment is one that just prints "hello, world" to standard output (and indeed it is the first example program in k&r). Environments that generate an unreasonably large executable for this trivial test or which require a hairy compiler-linker invocation to generate it are considered bad (see x).
