Loop through multimap and print out value key pair

#include <map>
int main()
{
   std::multimap< int, double, std::less< int > > pairs; // declare the multimap pairs
   // insert two value_type objects in pairs
   pairs.insert( std::multimap< int, double, std::less< int > >::value_type( 15, 2.7 ) );
   pairs.insert( std::multimap< int, double, std::less< int > >::value_type( 15, 99.3 ) );
   cout << "Multimap pairs contains:\nKey\tValue\n";
   // use const_iterator to walk through elements of pairs
   for ( std::multimap< int, double, std::less< int > >::const_iterator iter =pairs.begin();
      iter != pairs.end(); ++iter )
      cout << iter->first << "\t" << iter->second << "\n";

   cout << endl;
   return 0;
