std::vector<T,Allocator>::data
T* data() noexcept; | (since C++11) | |
const T* data() const noexcept; | (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).
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.
