# std::vector::data

From cppreference.com
< cpp‎ | container‎ | vector

[edit template]

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 (`data()` is not dereferenceable in that case).

### [edit] Parameters

(none)

### [edit] Return value

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

### [edit] Complexity

Constant.

### [edit] Exceptions

`noexcept` specification:
noexcept

back | access the last element (public member function) [edit]
