const T* data() const noexcept; (until C++17)
constexpr const T* data() const noexcept; (since C++17)

Returns pointer to the underlying array serving as element storage. The pointer is such that range [data(); data() + size()) is always a valid range, even if the container is empty (data() is not dereferenceable in that case).



Return value

Pointer to the underlying element storage. For non-empty containers, the returned pointer compares equal to the address of the first element.




If size() is 0, data() may or may not return a null pointer.
