Hello World is the canonical 'shortest example program' in any given programming language; a program which simply prints 'hello, world', and then terminates.
The first version appeared in "A Tutorial Introduction to the Programming Language B":
main( ) {
extrn a, b, c;
putchar(a); putchar(b); putchar(c); putchar('!*n');
}
a 'hell';
b 'o, w';
c 'orld';
It was popularized with one in the 'C Tutorial' in UNIX V6:
main() {
printf("hello, world");
}
