C++實現快捷店會員管理系統_C 語言

作者：一只代碼魚 ? 更新時間： 2022-05-21 編程語言

本文設計C++快捷店會員的簡單管理系統。基本要求如下：

（1）定義人民幣RMB類(數據成員包括元，角，分三個整型變量)，實現人民幣的基本運算(對操作符+和－運算進行重載)和顯示(顯示元，角，分)。

（2）定義會員member類，表示會員的基本信息，包括：編號（按建立會員的順序自動生成），姓名，密碼，電話。提供輸入、輸出信息等功能。

（3）由RMB類和member類共同派生一個會員卡memberCar類(含有memberCar類型next指針變量)，提供新建會員、充值、消費和查詢余額等功能。

（4）main函數定義一個memberCar類鏈表，保存會員卡，模擬一個快捷店的會員卡管理功能，主要包括：

1）、 新建會員(檢查輸入的會員電話號碼是否已經存在；若存在，則表示已經有該會員，需要重新輸入會員信息)，則為該會員建立會員卡，將該會員卡所表示的對象插入memberCar類鏈表表尾；

2）、已有會員充值(需要對充值進行非負性檢查)；

3）、已有會員消費（憑密碼，不能透支）；

4）、輸出快捷店當前會員數，當前所有會員的消費總額，所有會員卡剩余的額度總數；

5）、遍歷鏈表，輸出所有會員卡的信息(不能輸出會員個人密碼)；

6）、建立一個文本文件“member.txt”，將所有會員信息存入該文件中；

7） 、建立一個二進制文件“member.dat” ，將所有會員信息存入該文件中；

8） 、建立指針數組，初始化指針數組，存儲鏈表中每個會員對象的地址；對鏈表中的每個會員按照消費額度按照從小到大進行排序(要求不能改變鏈表的邏輯結構)，并將排序后的會員對象的地址存在指針數組中；

9）、利用(8)中的指針數組，在屏幕上輸出會員的排序結果。
