When you open the files using ifstream constructor , the failbit is not affected.

You should check the failbit status with is_open() member function.

ifstream fin(file_name) ;
if(!fin)
{
    cout<< "Don't do this"<<endl ;
}

if( !fin.is_open())
{
    cout<<"Do this to check the status"<<endl ;
}

I doubt you have done the previous one and not the latter one. So, change your
code accordingly
and come back here with your results.
