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
