Re: [Boost-users] [tokenizer] mutable string iterator

Thanks Pavol,

I was able to get my problem solved by using the split algorithm:

void reverse_word( iterator_range< string::iterator >& range )
{
   reverse( range.begin(), range.end() );
}

int _tmain(int argc, _TCHAR* argv[])
{
   string str( "    Hello    World" );

   typedef vector< iterator_range< string::iterator > > find_vector_type;
   find_vector_type vec;
   split( vec, str, is_any_of(" ") );

   for_each( vec.begin(), vec.end(), reverse_word );

   cout << str << endl;

        return 0;
}

But is there a way to use the split iterator? I wasn't able to create
one for my problem.

Thanks,
Christian
