If there isn't any obvious source handle and for some cause defining a proper RAII object/handle is infeasible,

Nevertheless, vectorization is effective greatest with simple data constructions and with algorithms particularly crafted to permit it.

: the ideal version of some thing we're striving for. Typically we really have to make trade-offs and accept an approximation.

For existing stdlib functions and kinds like vector that are not totally bounds-checked, the purpose is for these characteristics to get bounds-checked when named from code While using the bounds profile on, and unchecked when named from legacy code, quite possibly applying contracts (concurrently currently being proposed by various WG21 members).

Generally you need to add and take away aspects from the container, so use vector read this post here by default; in the event you don’t have to have to modify the container’s sizing, use array.
