    The fstream is supposed to be a replacement of the stdio.h and the exception
    is supposed to be a replacement of the return error code. So how do I
    replace my old codes of the style:

    if (output = fopen(...) == NULL) {
        perror("...");
        exit(1);
    }

    by the C++ style? The only thing I can do now is like

    fstream output("...", ios_base::out);
    if (!output.is_open()) {
        cerr << "..." << endl;
        exit(1);
    }

    how do I use exception here? Or I should not?
