#include< iostream.h >

};

/*intream& operator >>( ostream &o,TPolynomialItem &a)

*/
void main()
{
  TLinearListLink <TPolynomialItem>&c,&d;
  cout<<" Please input a polynomial c :"<<endl;
  cin>>c;
  cout<<"Please input a polynomial d :"<<endl;
  cin>>d;

  cout<<" After adding c become to :"<< TPolynomialAdd(c,d)<<endl;



}
我改过来改过去总有点错误，我调试不出来，希望大家能帮帮我~~

真的很急！！！！1
