银行账户管理程序
问题描述:
设计一个银行账户管理程序，账户的信息有账号（唯一）、姓名、余额、身份证号码、单位、电话号码、地址等，允许用户进行如下操作：开户、销户、存款、取款、转账、查询，一个用户可以有多个户头，账户的数值没有上限。
基本要求
程序运行时，可以由用户选择进行何种操作，开户操作要求输入用户信息后自动获取账号，用户销户后账号被回收，并且该账号可以继续分配给其它账户，不允许用户透支，根据姓名或账号可以进行用户的信息查询，所有的账户信息应存放到一个文件中，可以随时的访问和更新。
测试数据
程序应输入不少于10人的账户信息，应考虑到人员同名的情况。
实现提示
可定义一个账户类存放账户信息以及执行相应的操作，可以用一个链表类来管理账户。
选作内容
在上述程序的基础上，添加联名账户（一个联名账户有两个拥有者）的管理 。
