惨了，表示看不懂~！

稀里糊涂的人不适合学编程，因为那需要严谨

template<typename Iter>
void print( Iter first, Iter last, const char* nm="", const char* seq="\n", std::ostream& os=std::cout )
{
    if( nm!=0 && nm[0]!='\0' )
        os << nm << ":" << seq;

    typedef typename std::iterator_traits<Iter>::value_type T;
    copy( first, last, std::ostream_iterator<T>(os,seq));
    os << std::endl;
}
