Evolución de un programador

http://www.abadiadigital.com/noticia2631.html

(post extenso ahead!XD)

Los que seáis programadores o tengáis pensado serlo: ¿os sentís identificados con la evolución profesional de este programador estándar que paso a mostraros? El artículo no deja de ser una parodia un tanto exagerada pero...

En el Instituto:

10 PRINT "HELLO WORLD"
20 END

Primer año en la Universidad:

program Hello(input, output)
begin
writeln('Hello World')
end.

Último año en la Universidad:

(defun hello
(print
(cons 'Hello (list 'World))))

Primer trabajo:

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

for(i = 0; i < 2; ++i)
printf("%s", message[i]);
printf("\n");
}

Profesional con varios años de experiencia:

#include
#include

class string
{
private:
int size;
char *ptr;

string() : size(0), ptr(new char[1]) { ptr[0] = 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 << s.ptr);
}

string &string::operator=(const char *chrs)
{
if (this != &chrs)
{
delete [] ptr;
size = strlen(chrs);
ptr = new char[size + 1];
strcpy(ptr, chrs);
}
return(*this);
}

int main()
{
string str;

str = "Hello World";
cout << str << endl;

return(0);
}

Aprendiz de Hacker:

#!/usr/local/bin/perl
$msg="Hello, world.\n";
if ($#ARGV >= 0) {
while(defined($arg=shift(@ARGV))) {
$outfilename = $arg;
open(FILE, ">" . $outfilename) || die "Can't write $arg: $!\n";
