That's just a misuse of the std::vector. You never, ever get the idea of taking the address of an empty array. Why attempt that on an empty vector??
Dunno what you mean by "get the idea of taking the address," but this is a perfectly reasonable thing to do in C.
Writing x[n] is undefined behavior in C++ whenever n >= the length of the array. Is C different in that regard? -- Dave Abrahams Boost Consulting http://www.boost-consulting.com The Astoria Seminar ==> http://www.astoriaseminar.com
