试了，没有问题啊，不知道大大说的漏洞是指什么？

不正死机啊或者什么吗

不是的，是指有什么BUG，比如说，修改密码不成功什么的，注册两个相同的帐号等等！

一个挺好的程序

如果一定要说有什么漏洞的话,我觉得是

容错处理不好,我乱输入点什么就可以进入死循环.

还有我想看看这个程序的源文件,和版权无关,只想学习一下,

可以吗?

方便的话打包上来,或是发到邮箱里.

谢谢先,

我想在除了输名字和密码时，其它时候每步都加上验证是否是数字这步吧

我刚学不知道说的有没有错

这个问题是不是在进行数据处理的时候产生的啊？

如果你按照步骤一个一个的输入，输入一个数按一次回车，这样就不会出现死循环。

其实代码挺简单的，都是基本知识的综合运用。

代码有点长，我又没加注释：
