            // Pick any of the following three options...

            // Print the pieces out one at a time. This is kind of wordy, but
            // does things one at a time, which may make the most sense, if you're
            // just getting started.

            // bunch of programming before, you may prefer it. This uses a version
            // of the WriteLine method that we haven't talked about yet, which has
            // a variable number of arguments, which are substituted in.
            // This allows you to separate your formatting from your data, which
            // follows the principle of separation of concerns.
