I learned [and taught Ada] before I learned [and taught C].

The ".h" files in C are pretty much like Ada package specifications,
and "static" is pretty much like "private".

Unfortunately, the C textbooks I deal with don't seem to have much sense
of programming in the large, and really do not give the sort of treatment
to how these features can be exploited as I would like.

Depending on the size of your project, it may be worth your while to acquire
or develop a tool to enforce certain standards, such as prohibiting any
global symbols from being present in a ".c" file that are not also in the
".h" file. Some compilers will warn you of such things, some not.
Make LINT a habit.

But if you are re-training Ada programmers to program in C, then you should
have a fairly easy time with this aspect. If you are using ANSI-C instead of
C++ you will probably miss things like overloading.

Hope this helps; I might think of more issues later.
