I said that they were equally expressive, because the claim was that C++ is more powerful than C. >VLA in C are on the stack vectors are allocated from dynamic memory (heap) That is not necessarily true. It's an implementation detail, and as far as it's relevant, so is the fact that everyone supports VLAs in C++. >Right but that is why in practice C++ it is not a strict superset of C Nobody said that C++ was a strict superset of C. The claim was that C++ is more powerful than C, and the fact that you have to specifically request ABI compatibility is not evidence to the contrary. Rather, the fact that you can do this at all (and that you can't use C++ linkage in C) is evidence in support of it.
