超市会员管理系统

好难啊！还要再改！

————————————————————————————————————————————

超市会员管理系统要求
·系统菜单分为两级
一级菜单：登录、开卡、退出系统
二级菜单(登录之后)：积分累积、积分兑换、积分查询、修改密码、退出登录

·开卡的账号不能重复

·验证用户名
用户名不能以数字开头，不能有特殊符号，用户名长度必须是3-6位之间
·验证密码
密码长度必须是6-16位之间，不能有中文、空格，验证密码强度：
纯数字、纯英文是低，数字+英文是中，数字+英文+特殊字符是高
·开卡时需要输入验证码，验证码不区分大小写

·输入积分、消费金额时，必须是数字，若不是数字重新输入

·修改密码如果是旧密码则提示修改失败，如果是新密码也要验证密码，并且修改成功后需要退出重新登录

·登录时，如果密码连续输入五次失败，则冻结当前账户

·登录时，有忘记密码提示，所以要求要实现密保问题验证，在忘记密码时能够找回密码
