But both results in processing last line twice, because getline return value is not checked before calling cout <<

Yes, I pointed that out earlier; that's why they are only somewhat correct.

Only those intended for DOS/Windows/OS2 - "d:" does not have ANY meaning for paths in for example Linux.

Also:
"fstream.h"

Is old style, new code should use:
<fstream>

[Even if you use old style headers, you should use angle-brackets, not quotes for system headers - and I presume you are not developing your own fstream implementation].

One is in the current directory on d:, the other one is in the root directory of d: - they are only the same for the case where current directory == root directory.
