std::vector::data

T* data();

const T* data() const;

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).

Parameters

(none).

Return value

Pointer to the underlying element storage. For non-empty containers, returns &front().

Complexity

Constant.
