The class isn't pure virtual as we don't actually have any platform-specific code to add as this is an
exercise for illustrative purposes. You can imagine that a proper base class for platform abstraction
would have pure virtual methods that would have platform-specific code added.
The next step is to create three classes for our different platforms. These are shown in Listing 26-6.
