}

問題是，當我調用choice5() 函數時，它會出現錯誤：

*-IntelliSense：沒有合適的從“書籍”到“書籍”的轉換功能

*-IntelliSense：沒有合適的從“書籍”到“書籍”的轉換功能

-錯誤 C2664：'void choice5(books [],books [],int,int)': 無法將參數 1 從 'books' 轉換為 'books []

不知道是參數問題還是什么！！

選擇5(); 提交書籍后，函數調用在 if(choice==5) 的 main 中

我就像 C++ 的 1 級，所以我正在盡我所能讓它更小

Answer 1

不知道是參數問題還是什么！！

編譯器會准確地告訴您問題出在哪里：您對choice5的調用。 第一個參數是一個books數組，你傳入的是一個book 。

choice5(new_book[i], aut[j], books_number, aut_number);

new_book是一個數組， new_book[i]是數組中的特定book 。 aut 。

Answer 2

函數choice5(books new_book[],books aut[], int books_number,int aut_number) 必須接收一個books 數組或指向結構books 的指針作為第一個參數。 第二個參數“aut”也會有同樣的問題。 為了與函數定義匹配，您的呼叫應具有以下格式：choice5(new_book, aut, books_number, aut_number)
