Copy std::stack into an std::vector

Question

Is the following code guaranteed by the standard to work(assuming st is not empty)?

#include 
#include 
int main()
{
   extern std::st         


        

Answer 1

Only std::vector is guaranteed by C++03 to have contiguous elements (23.4.1). In C++1x this will be extended to std::string as well (defect #530).
