  你这个程序也应该是google出来的吧，我早就看到过了&# 8230;&# 8230;


  在08-3-2，marryme <beyond0924 at gmail.com> 写道：
    #include <iostream>
    #include <string>
    #include <iterator>
    #include <list>
    #include <algorithm>
    using namespace std;
    template<typename T, typename ForwardIterator=T::iterator>//模板的默认参数
    struct  print
    {

      void operator() (T& coll, ForwardIterator it=coll.begin() )//函数的默认参数
      {

        copy( coll.begin(),coll.end(),ostream_iterator<T::value_type>(cout,"\n"));

      }
    };
