Example 1: (a) STL find algorithm; (b) switching from a C array to an STL list.

    (a) int numbers[ 100 ] :
           ....
        int* i = find( numbers, numbers + 100, 37 );

    (a) list< int > numbers;
           ....
        list< int >::iterator i =
         find( numbers.begin(), numbers.end(), 37 );
