[Dev-C++] fstreams

[alfonso s. m. <as...@gm...>]

Hi, I am a new user changing from VisualC++ to Dev-C++. I have a problem
with fstreams:

1) if I open an fstream with in mode, close it (without doing anything, just
for testing) then I can re-open it, BUT

2) if I open an fstream with in mode, read all the file and close it THEN I
cannot re-opening any more.

May anyone help me? Thanks,
