cin is the object of istream class.
cout is the object of ostream class.

So, It made <iostream.h> header file.

If I include <iostream.h> I am going to get a compile-time error because
the default(in the way of default directory) library is <iostream> not <iostream.h>.

Try to do it in turbo c++, you won't get any error!
