Question

In C++, is there a struct (or class) defined representing a pair of iterators — one the beginning and one the ending iterator? What’s best practice to represent that? std::pair? I know that I can easily build that myself, but I would like to follow common practice.

I search for the following:

template<class It>
struct XXX {
private:
   It b;
   It e;
public:
   It begin () const { return b; }
   It end () const { return e; }
   // ...
};

Have a look at Boost.Range, in particular boost::iterator_range.
