forward_list::cend() is a function in C++ STL which returns a constant iterator pointing to the past-the-last element of the forward_list. The iterator returned by the function does not point to any element in the container, but to the position followed by the last element of the forward list container.
The iterator returned by the function points to constant content. Since the iterator itself is not constant it can be increased or decreased or modified but it cannot be used to modify its content even if the forward list is not constant.
Since the iterator does not point to any element of the forward list, it cannot be dereferenced in any case.
Parameters: The function does not take any parameter.
Return Value: The function returns an iterator pointing to the past-the-end element of the forward list container.
The following programs illustrates the use of the forward_list::cend() function:
