这里账户数据文件名已经设定为account.txt,这个文件要和上面这个程序放在同一个文件夹下面,不然就得用绝对路径(比如"d:\\book\\account.txt"),account内容可以用记事本打开自己改动,然后运行程序后就可以在程序中添加或删除。account.txt一个参考内容如下:
1 10023 zhangsl 100.50
2 32001 sunq 5000.00
3 20010 wangxi 2500.00 4
你学习的应该是C# 把。提问问题要分类啊。
银行储蓄管理系统,首先要考虑银行的业务啊。这个就需要你去搜索银行的主要业务了。
数据表应该和下面有关,用户 利息 贷款 会员 当然也可以包括其他的一些了,利于水电费 旅游 等等。
功能:能够输入和查询客户存款取款记录。在客户文件中,每个客户是一条记录,包括编号、客户姓名、支取密码、客户地址、客户电话、账户总金额;在存取款文件中,每次存取款是一条记录,包括编号、日期、类别、存取数目、经办人。类别分为取款和存款两种。本系统能够输入客户存款或取款记录;根据客户姓名查询存款和取款记录。分步实施:1、初步完成总体设计,搭好框架,确定人机对话界面,确定函数个数;2、建立一个文件,输入客户的必要信息,能对文件进行显示、输入、修订、删除等。3、进一步要求:完成客户姓名查询存款和取款记录,并能得到每次帐户总金额。要求:1、用C语言实现系统;2、利用结构体数组实现信息的数据结构设计;3、系统的各个功能模块要求用函数的形式实现;4、界面友好(良好的人机交互),程序加必要的注释。课程设计实验报告要求:1、预习报告:题目、课程设计任务、数据结构、程序的总体设计(算法)、模块划分 。2、实验总结报告:流程图、主要源程序代码(需打印)、测试情况及调试中问题与解决方案、小结等要求:标明所用函数的用途和目的,简单叙述制作思路。是否可以解决您的问题?
