insertAsFristElement未在此範圍內聲明

Question

我有關於工作人員數據的一般性工作以及我的方式，因爲我仍然存在此錯誤。如果有人願意幫助我請。 這是代碼索裏的郎是阿爾巴尼亞：

你有一個錯字

void insertAsFristElement(pun *&head, pun *&last, int ID); 
      ^^^^^ 

或

void insert (pun *&head, pun *&last, int ID){ 
    if (isEmpty(head)) 
     insertAsFirstElement(head,last,ID); 
       ^^^^^ 

我想你的意思

void insertAsFirstElement(pun *&head, pun *&last, int ID); 
      ^^^^^
