Hi,

I am using g++ 2.0. I am using fstream class to use a file.

Problem1:
--------
For example,
 fstream myfile ("a.file",ios::in|ios::nocreate);
 if (!myfile.is_open()) // do something;

In some programs, i do not get compilation error and in some
programs i get no fstream::is_open error. Even if i do not
get compilation error, the system hangs. Can some one suggest
some solution?.

Problem2:
---------
while (!myfile.eof()) {myfile >> a;}

goes in a loop. It is not sensing eof. For this also, i need
some suggestion.

Thank you,
Santhi.
