Dando una vuelta por la web de nuestro amigo Francisco Jesús, me encontre con esta autentica joya La evolución de un programador tipo, desde sus tiernos comienzos en basic hasta que llega a ser jefe ejecutivo de la empresa…
Espero que os sirva almenos para pasar un rato agradable.
The Evolution of a Programmer
—————————–
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”);
}
Seasoned professional
=====================
#include
#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 << 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);
}
