Notice that the `main` program is complete, while the rest
of the functions are merely stubbed out. The interface of each
function has been defined, i.e. how many and what types of parameters
are expected as well as what will be returned, but the functions
have not yet been implemented. Comments have been included inside the
function definitions as reminders for how we expect to implement them.
