const_iterator cbegin() const noexcept;		(since C++11)

Returns an iterator to the first element of the container.

If the container is empty, the returned iterator will be equal to end().

Parameters

(none)

Return value

Iterator to the first element

Complexity

Constant

Notes

Because both iterator and const_iterator are constant iterators (and may in fact be the same type), it is not possible to mutate the elements of the container through an iterator returned by any of these member functions.

returns an iterator to the end (public member function)
