readability-container-data-pointer¶

Finds cases where code could use data() rather than the address of the element at index 0 in a container. This pattern is commonly used to materialize a pointer to the backing data of a container. std::vector and std::string 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.
