Use std::copy to print all elements in a multiset : multiset « set multiset « C++ Tutorial

#include <iostream>
using std::cout;
using std::endl;

#include <set> // multiset class-template definition

#include <algorithm> // copy algorithm
#include <iterator> // ostream_iterator

int main()
{
   int a[ 10 ] = { 7, 22, 9, 1, 18, 30, 100, 22, 85, 13 };
   std::multiset< int, std::less< int > > intMultiset;
   std::ostream_iterator< int > output( cout, " " );

   // insert elements of array a into intMultiset
   intMultiset.insert( a, a + 10 );
   cout << "\nAfter insert, intMultiset contains:\n";
   std::copy( intMultiset.begin(), intMultiset.end(), output );


   cout << endl;
   return 0;
}

After insert, intMultiset contains:
1 7 9 13 18 22 22 30 85 100
