C++ will NEVER replace C. Not gonna happen. C compiles to much more
efficient code in many cases because of the template constructs in
C++. If you can avoid templates at all costs, you get very close, and
only a few cases will cause slower code in C++. However, when it
comes to operating systems, I suspect it will be a long time before
people start using something besides C.

I think it was established in the previous thread that this was
definitely NOT the case. In fact, I learned C++ before I learned C.
That isn't to say you can become a real C++ expert without learning C,
so while I disagree with the statement that C is a prerequisite of
C++, I agree that becoming intimately familiar with C first is a very
good idea. I found the underlying basics of C much easier to grasp
than C++, so learning C first might have made C++ easier.
In addition, regardless of the fact that C++ is not quite a superset
of C, there are still times when it will be worthwhile, usually for
the sake of efficiency, to bypass the C++ standard constructs and
build your own using more of a 'clean C' approach.
