The Evolution of Code...

High School / Junior 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 Profesional :

#include
void main(void)
{
char *message[] = ("Hello ", "World.");
int i;

for (i = 0; i <>
#include
class string
{
private:
int size;
char *ptr;
public:
string () : size (0), ptr (new char('\0')){}
string (const string &s) : size(s.size)
{
ptr = new char (size + 1);
strcpy (ptr, s.ptr);
}
~string()
{
delete [] ptr;
}
friend ostream &operator << (ostream &, const string &); string &operator = (const char*); }; ostream &operator << (ostream &stream, const string &s) { return (stream << operator =" (const" size =" strlen" ptr =" new" str = "Hello World." msg="Hello World.\n">= 0) {
while (defined($arg=shift(@ARGV))) {
$outfilename = $arg;
open (FILE, ">" . $outfilename) || die "Can't write $arg: $!\n";
print (FILE $msg);
close (FILE) || die "Can't close $arg: $!\n";
}
} else {
print ($msg)
}
l;

#include
#define S "Hello World.\n"
