I've look in the C++ standard and, when listing list of compound stuff, it does not mention anything like "pointer to [B]data [/B]member of an instantiated class". So the question is: [CODE]struct test{ int a; double d; ..... //more complicated stuff here to make it a NON-pod structure) .... }; …

Hi guys, I'm having trouble using a pointer to a vector<float>, it doesn't seems to be responding as I'm expecting it to. Probably a silly mistake on my behalf, but would anyone kindly point it out please.
