*设计方案：本程序分为七个模块：1、新建人事信息模块 2、查询模块 3、删除模块 4、添加模块 5、修改模块 6、打印模块 7、数据备份与还原模块。

每个模块相互独立。且每个模块只完成一个功能，用一个函数实现。在主函数中调用这些模块。每个模块处理的信息即人事基本信息用结构体存储，数据结构采用链表实现，最终以文件形式存储于磁盘上。*/-* Design: This procedure is divided into seven modules: 1, New Personnel Information Module 2, Query Module 3, delete the module 4, add the module 5, modify module 6, printing module 7, data backup and restore module. Each module are independent of each other. And the completion of each module is only a function of a function. Call in the main function of these modules. Each module to deal with information that is basic information and personnel with the structure storage, data structures using list to achieve the ultimate form of a document stored on disk.* /
