Evolution of Programmer

Guys, gue lagi bingung mau nulis apa. Jadinya, gue sedikit mengambil dari sini. Inti tulisannya kayak gini. Nikmati aja.

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");
 }
