Muchos ya lo sabreis, pero yo me vengo dando cuenta
ahora, que el compilador de C++ se ha empezado a
quejar, asi que aqui va la nota del dia.
=======================================
<iostream.h> or <iostream>?
=======================================
Although the <iostream.h> library was deprecated for
several years, many C++ users still use it in new code
instead of using the newer, standard compliant
<iostream> library. What are the differences between
the two? First, the .h notation of standard header
files was deprecated more than 5 years ago. Using
deprecated features in new code is never a good idea.
In terms of functionality, <iostream> contains a set
of templatized I/O classes which support both narrow
and wide characters. By contrast, <iostream.h> classes
are confined to char exclusively. Third, the C++
standard specification of iostream's interface was
changed in many subtle aspects. Consequently, the
interfaces and implementation of <iostream> differ
from <iostream.h>. Finally, <iostream> components are
declared in namespace std whereas <iostream.h>
components are declared in the global scope. Because
of these substantial differences, you cannot mix the
two libraries in one program. As a rule, use
<iostream> in new code and stick to <iostream.h> in
legacy code that is incompatible with the new
<iostream> library.

Pos eso, que a usar iostream a partir de ahora
