C++银行管理系统方案.docx

1、C+银行管理系统方案基于C/C+实现银行管理系统声明：1.本程序仅限个人交流和学习使用，切勿用于商业用途，一切源代码已经给出，可以根据自己的需要适当进行修改，但请保留原来的作者的信息。2.程序里面难免有一些考虑不周到的地方，如果能够通过QQ或者告知，本人将万分感。 聊城大学 软件工程（和惠普合作培养软件开发）宇鹏2015年6月一程序设计要求：设计并实现简单的银行存取款系统，系统主界面包括登录和注册两个选项，选择登录，提示用户输入银行和密码，验证通过后进入主界面，主界面包括：存款、取款、查询余额、历史记录、修改密码等功能。注册功能让用户输入和密码，在注册时要验证是否已经存在。所有数据能够保存在文

2、件中，退出系统后再次运行系统，之前注册的用户和存款信息都存在。二程序实现的大致思路：1.登陆界面和主界面的设计采用一行行printf输出。2.登陆界面-主界面的切换采用system(“cls”)函数。3.主界面的所有操作都涉及到了文件操作，所以采用3个文件分开储存和读取的方式。（1）存取款以及查询余额：（2）历史记录：（3）账户密码信息：三、程序算法和数据结构：1.登陆用户：从文件里面读取信息，把用户名和密码分别压栈，读取结束，验证用户的名字和密码和栈顶元素是否匹配，不匹配栈顶元素出栈，直到栈的容量是空的时候。返回信息：用户或者密码错误。2.存款取款以及余额的查询： 每次建立一个新的用户的时候

3、，初始化此用户的所有信息。（主要是针对的余额）。从文件里面读取信息，采用二叉树的结构搜索用户。来实现查找。 采用文件的重新写入来实现存取款。四、程序的一些设计的技巧以及注意情况：为了使程序模块化，我们要采用多文件的开发。也就是说，为了使程序简练，把一些需要重复利用的代码写到.h 的文件里面。五、代码实现：#include stdafx.h#include #include #include #include #include #include #include #include #include #include #include Welcome_UI.h#include Register_U
