“Hello World” is the first program one usually writes when learning a new programming language. Having first been mentioned in Brian Kernighan’s tutorial to the B programming language, it became widely known through Kernighan & Ritchie’s 1978 book that introduced“The C Programming Language”, where it read like this:

main() {
    printf("hello, world\n");
}
