※ 引述《whitesheep1 (月兒天邊高高掛)》之銘言：

: C:\Documents and Settings\莊皓翔\桌面\hw819.cpp(34) : error C2511: '+' :
: overloaded member function 'class polynomial (class polynomial &)' not found in
: 'polynomial'
: C:\Documents and Settings\莊皓翔\桌面\hw819.cpp(6) : see declaration of

: 不知道 哪裡錯了 誰幫幫我 謝謝^^
:是不是在function declaration中改成
:
: polynomial operator+(polynomial & );
:
: 才對？
