Returns a const_iterator pointing to the past-the-end element in the forward_list container.
A const_iterator is an iterator that points to const content. This iterator can be increased and decreased (unless it is itself also const), just like the iterator returned by forward_list::end, but it cannot be used to modify the contents it points to, even if the forward_list object is not itself const.
The value returned shall not be dereferenced.
Member type const_iterator is a forward iterator type.
Output:
No contained elements are accessed by the call, but the iterator returned can be used to access them. Concurrently accessing or modifying different elements is safe.
The copy construction or assignment of the returned iterator is also guaranteed to never throw.

const_iterator cend () const noexcept;
Return const_iterator to end
A const_iterator is an iterator that points to const content. This iterator can be increased and decreased (unless it is itself also const), just like the iterator returned by forward_list::end, but it cannot be used to modify the contents it points to, even if the forward_list object is not itself const.
The value returned shall not be dereferenced.
Parameters
noneReturn Value
A const_iterator to the element past the end of the sequence.Member type const_iterator is a forward iterator type.
Example

Output:
mylist contains: 21 32 12 |
Complexity
Constant.Iterator validity
No changes.Data races
The container is accessed.No contained elements are accessed by the call, but the iterator returned can be used to access them. Concurrently accessing or modifying different elements is safe.
Exception safety
No-throw guarantee: this member function never throws exceptions.The copy construction or assignment of the returned iterator is also guaranteed to never throw.
