Returns an iterator referring to the past-the-end element in the forward_list container.
The past-the-end element is the theoretical element that would follow the last element in the forward_list. It does not point to any element, and thus shall not be dereferenced.
Because the ranges used by functions of the standard library do not include the element pointed by their closing iterator, this function is often used in combination with forward_list::begin to specify a range including all the elements in the container.
If the container is empty, this function returns the same as forward_list::begin.
If the forward_list object is const-qualified, the function returns a const_iterator. Otherwise, it returns an iterator.
Member types iterator and const_iterator are forward iterator types (pointing to an element and to a const element, respectively).
Output:
No contained elements are accessed by the call, but the iterator returned can be used to access or modify elements. Concurrently accessing or modifying different elements is safe.
The copy construction or assignment of the returned iterator is also guaranteed to never throw.

Return iterator to end
The past-the-end element is the theoretical element that would follow the last element in the forward_list. It does not point to any element, and thus shall not be dereferenced.
Because the ranges used by functions of the standard library do not include the element pointed by their closing iterator, this function is often used in combination with forward_list::begin to specify a range including all the elements in the container.
If the container is empty, this function returns the same as forward_list::begin.
Parameters
noneReturn Value
An iterator to the element past the end of the sequence.If the forward_list object is const-qualified, the function returns a const_iterator. Otherwise, it returns an iterator.
Member types iterator and const_iterator are forward iterator types (pointing to an element and to a const element, respectively).
Example

Output:
mylist contains: 10 20 30 40 |
Complexity
Constant.Iterator validity
No changes.Data races
The container is accessed (neither the const nor the non-const versions modify the container).No contained elements are accessed by the call, but the iterator returned can be used to access or modify elements. 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.
