vector::cend
Returns a const iterator that point to one past the last element in the vector.
const_iterator cend() const;
Return Value
A const random-access iterator.
Remarks
cend is used to test whether an iterator has passed the last element in the vector.
You can use this member function in place of the end() member function to guarantee that the return value is const_iterator. Typically, it's used in conjunction with the auto type deduction keyword, as shown in the following example. In the example, consider Container to be a modifiable (non-const) container of any kind that supports end() and cend().
auto i1 = Container.end(); // i1 is Container<T>::iterator
auto i2 = Container.cend(); // i2 is Container<T>::const_iterator
The value returned by cend should not be dereferenced.
