    while (a_file_that_will_be_working_with)
    {
        // read stuff from the file into a string and print it
        string strInput;
        a_file_that_will_be_working_with >> strInput;
        cout << strInput << '\n';
    }
     return 0;
}

What have I done wrong? When I use ifstream to read from a file it works, but it doesnt for fstream, I thought fstream is both ofstream and ifstream combined.

See https://en.cppreference.com/w/cpp/io/basic_fstream for an example.

You need to "rewind" the file to read just written stuff (s.seekp(0);).
