Hi, your question is bit unclear... what are you storing in the multimap logically. What I've understood is that you want to get the multiple values against the same key [code=cpp] multimap<int, string> mm; mm.insert(std::make_pair(1, "a")); mm.insert(std::make_pair(1, "c")); mm.insert(std::make_pair(2, "d")); mm.insert(std::make_pair(2, "e")); typedef pair<multimap<int, string>::iterator, multimap<int, string>::iterator> Pair_Range; Pair_Range pRange …
