Previously, the includes in the initial walkthrough section were
different from the actual ones used includes in the code example.
Moreover, if one was following the walkthrough and only taking
inspiration from there rather than the code itself, with these includes,
the code wouldn't compile. Synchronize the source code file with the
walkthrough in this regard.
