This is false in the first sentence, but the second is always true. If you
have a group of junior device driver developers, the limited environment in
"C" can help keep them from shooting themselves in the foot. Cobol is even
better at allowing almost anyone with minimal skills to be a coder, though
it takes a long time for them to become a programmer.

I use C++ in my device drivers because it makes sense. I use the .cpp
extensions even if the code is still pure "C" because the latest Microsoft
compilers do a better job of catching errors. Since the stack is so limited
in kernel mode, the full capabilities of C++ exception handling don't belong
and aren't supported by Microsoft. Passing large data items on the stack is
another bad idea in either "C" or "C++".

I have been in environments, government, where you are give some people who
the "system" says are programmers. You have a job to do and they are your
resources. Sometimes you just have to apply the KISS principle even in your
choice of language. Luckily in today's civilian job environment, you can
get rid of the non-performers, but it much more difficult in the military or
civil service. It takes a supervisor at least a year to get a civilian
fired for incompetence and most supervisors don't have that much time to
devote to that. It is easier to get the person promoted or transferred.
