@VoltrexKeyva 

The pattern of getting the address of the element at index 0 of a
container is generally used to materialize a pointer to the backing
data of a container, however `std::string` and `std::vector`
provide a `data()` accessor to retrieve the data pointer which
should be preferred.

This also ensures that in the case that the container is empty, the
data pointer access does not perform an errant memory access.
