Fstream fails to create new file

Question

I\'m using a FileManager for a project so that reading and writing is less of a hassle for me. Or would be, if I didn\'t spend all this time debugging it. So, this comfort-c

Answer 1

Best method:

void FileManager::open(std::string const& filename)
{
    using std::ios_base;
    if( stream_.is_open() )
        stream_.close();

    stream_.open( filename.c_str() ); // ...try existing file
    if( !stream_.is_open() ) // ...else, create new file...
        stream_.open(filename.c_str(), ios_base::in | ios_base::out | ios_base::trunc);
}

So the code tests for an existing file and, if not, creates it.
