Sounds like a pretty straightforward program to me. Why not just do it?
template<class Iter> class Cyclic_iterator {
public:
Cyclic_Iterator(Iter b, Iter e): begin(b), end(e), it(b) { }
Cyclic_Iterator& operator++() {
++it;
if (it == end)
it = begin;
return *this;
}
// and so on -- it's up to you to fill in the rest
private:
Iter begin, end, it;
};
