帮我用c++写一个通信录程序：并实现以下要求：基本要求： 定义人员（person）类，其中包括姓名、性别、电话号码、地址、邮政编码、邮箱、QQ号码和类别。 功能要求： 设计菜单实现功能选择； 输入功能：输入人员信息，并以txt格式保存到文件中； 查询功能： 能够根据姓名、电话精确查询人员信息； 能够根据地址进行模糊查询人员信息； 根据人员类别查询人员信息并输出显示； 能根据姓名、电话修改人员信息； 能根据姓名、电话删除人员信息； 根据姓名对人员信息排序输出； 根据QQ号码对人员信息排序输出； 根据电话号码对人员信息排序输出； 考虑重名问题的处理。 所有的增加、修改、删除能同步到txt文件；也从txt文件读取数据到程序。

好的，以下是一个简单的通信录程序，可以满足以上要求。请注意，这只是一个示例程序，具体实现可能会因人而异。
