Example 3

Example 3: (a) Standardizing all of the strings with a single call to the transform algorithm. (b) using the full generality of transform to combine the two steps into one. (c) sorting and removing duplicates.


    (a) transform ( words.begin(), words.end(),
                    words.begin(), standardize );

    (b) transform (istream_iterator< string, ptrdiff_t >( cin ),
                   istream_iterator< string, ptrdiff_t >(),
                   inserter( words, words.end() ),
                  standardize )


    (c) sort( words.begin(), words.end() );
        vector< string >::iterator i =
        unique( words.begin(), words.end() );
        copy( words.begin(), i,
           ostream_iterator< string > ( cout, "\n") );
