Using operator[] on empty std::vector

Question

I was advised a while ago that is was common place to use std::vector as exception safe dynamic array in c++ rather than allocating raw arrays... for exampl

Answer 1

Could you use iterators instead of pointers?

{
    std::vector scoped_array (size);
    std::vector::iterator pointer = scoped_array.begin();

    //do work

} // exception safe deallocation
