   list <int>::iterator c1_Iter;

   c1.push_back( 1 );
   c1.push_back( 2 );
   c1.push_back( 3 );
   c2.push_back( 10 );
   c2.push_back( 20 );
   c3.push_back( 100 );

   cout << "The original list c1 is:";
   for ( c1_Iter = c1.begin( ); c1_Iter != c1.end( ); c1_Iter++ )
      cout << " " << *c1_Iter;
   cout << endl;

   c1.swap( c2 );

   cout << "After swapping with c2, list c1 is:";
   for ( c1_Iter = c1.begin( ); c1_Iter != c1.end( ); c1_Iter++ )
      cout << " " << *c1_Iter;
   cout << endl;

   swap( c1,c3 );

   cout << "After swapping with c3, list c1 is:";
   for ( c1_Iter = c1.begin( ); c1_Iter != c1.end( ); c1_Iter++ )
      cout << " " << *c1_Iter;
