C++ Deque cbegin()

C++ Deque cbegin() function returns a constant iterator pointing to the first element of the deque container. This iterator can be incremented or decremented just like the iterator returned by the begin() function. If the container is empty then the returned iterator will be equal to the cend().

Syntax

Parameter

Return value
