I know that C++ is mostly, but not entirely, backwards compatible with C. That doesn't answer the question of what "C/C++" means. They're two different languages. The problem is that different people mean different things by "C/C++". Some people mean "C and C++"; others just seem to be unaware that they're distinct.
