The unordered_set::cend() method is a built-in function in C++ STL which is used to return a const_iterator pointing to past-the-end element in the unordered_set container or in one of it’s bucket. This function does not directly point to any element in the container. It is only used to denote the end of a container or the open end of a range as in [cbegin, cend).
Note: A const_iterator can only be used to access elements, it cannot modify the elements present in the container.
Parameter: This function accepts a single parameter n. This is an optional parameter and specifies the bucket number. If this parameter is not passed then the cend() method will return a const_iterator pointing to the position just after the last element of the container and if this parameter is passed then the cend() method will return a const_iterator pointing to the position just after the last element in a specific bucket in the unordered_set container.
Return Value: This function returns a const_iterator pointing to the position just after the last element in the container or a specified bucket in the container.
