#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, " " );

   intMultiset.insert( 15 );
   intMultiset.insert( 15 );


   // iterator that cannot be used to change element values
   std::multiset< int, std::less< int > >::const_iterator result;

   // find 15 in intMultiset; find returns iterator
   result = intMultiset.find( 15 );

   if ( result != intMultiset.end() ) // if iterator not at end
      cout << "Found value 15\n"; // found search value 15

   cout << endl;
   return 0;
}

Found value 15
