The sample programs in this subdirectory illustrate
the use of the static and extern keywords, as well
as the default automatic and static storage classes.
Study the source code and program output carefully.
Then perform some of your own "what if" experiments.
Note that there is no storage_linkage_main4.exe,
since one of the three possible pairs of like-numbered
comments must be activated to attempt building an
executable. Doing so for each of the three pairs is
left as an exercise.
