kgtemp文件怎么打开kgtemp文件怎么变成mp4…

C/C++银行管理系统

这是一个用C/C++写的银行管理系统的项目因为代码比较长，大家要有耐心的才能看下去。有什么错误，请大家指出。

如果有对编程感兴趣的可以加群大家一起交流学习，一起探索、感受编程的魅力，群里有学习资料，也有基础差，或者没有基础的朋友可以学习的书籍、视频资料

在这个项目中你可以记录日常的银行交易。这个项目可以持有任何帐户号码。

在第一个选项，你可以看到每个特定的人有一个特定的简单的账户号码。

第二选项，你可以看到所有的帐户列表。

通过第三个选项，你可以做银行业务（存/取）

第四选项，你可以打开新会计准则 NT。注：开户金额应不少于Rs.500/-.

在第五选项中，您可以修改或删除任何帐户。最后一个选项是退出（退出到拒绝服务）。
