Titolo: x programmatori lungo potrebbe far ridere l'1% delle persone ma lo posto...

L'evoluzione di un programmatore...
Ecco vari programmi che stampano tutti lo stesso messaggio: "Hello World"
===================
High School/Jr.High
===================
10 PRINT "HELLO WORLD"
20 END
=====================
First year in College
=====================
program Hello(input, output)
   begin
     writeln('Hello World');
   end.
======================
Senior year in College
======================
(defun hello
    (print
     (cons 'Hello (list 'World))))
================
New professional
================
#include
void main(void)
{
   char *message[] = {"Hello ", "World"};
   int i;
   for(i = 0; i < 2; ++i)
     printf("%s", message[i]);
   printf("\n");
}
