std::vector::data

T* data() noexcept;

const T* data() const noexcept;

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, the returned pointer compares equal to the address of the first element.

Complexity

Constant.

Notes

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