"A student in a C++ class at least has a chance at being exposed to something lower level." True, but the risk of using C++ in other CS classes is that they'll spend most of their time fighting C++, and not focus on whatever the class is supposed to be teaching. And the instructor/professor may be wasting a lot of time doing C++ tech support, rather than teaching compiler concepts, or whatever.
