transform example

 int  main()  {
         int  a1[ ]  =  {1, 2, 3, 4, 5};
         int  a2[ ]  =  {6, 7, 8, 9, 10};
         transform(a1,  a1 + 5,  a2,
                   ostream_iterator<int>(cout, "  "),
                   plus<int>());
         cout  <<  endl;
         transform(a1,  a1 + 5,
                   ostream_iterator<int>(cout, "  "),
                   bind1st(multiplies<int>(), 5));
