T* data();		(since C++11)
const T* data() const;		(since C++11)

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.

Parameters

(none)

Return value

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

Complexity

Constant.

Exceptions

noexcept specification:  

noexcept

  (since C++11)
