const_iterator for multimap
#include <map>
#include <iostream>
using namespace std;
typedef map <int, string> MAP_INT_STRING;
typedef multimap <int, string> MMAP_INT_STRING;
int main ()
{
MMAP_INT_STRING mmapIntToString;

{
cout << "Key: " << iMultiMapPairLocator->first;
cout << " Value: " << iMultiMapPairLocator->second.c_str ();
cout << endl;
}
return 0;
}Loop through multimap and print out value key pair
