7、序设计说明书的方法；5） 提高运用C语言解决实际问题的能力。2. 分析与设计：1） 系统需求：公民身份信息是国家最宝贵的基础信息资源之一，是制定与实施各种政策和指导经济建设的重要依据。利用现代信息技术进行公民身份信息资源的充分开发与利用，掌握人口信息的动态变化，对于国家加强社会管理，实现社会信息化将起到积极的推动作用。对于促进社会主义现代化建设和经济体制改革、打击犯罪、方便群众、保护公民的合法权益等都具有十分重要的意义。其建设的最终目标是实现与国家其它有关公民信息的系统实现互连互通，数据高度共享。为建立国家公民个人信用体系，为国家经济建设和社会发展做出贡献。因此，我想设计一个身份证信息管理软件

8、，用于对省份正信息的分类、管理和统计，从而方便公安机关和普通民众的查询。2） 设计思路：应用结构体对身份证信息进行添加、删除、查寻、修改、保存、统计和文件操作等。3） 综合任务:本次训练需要编写一个身份证信息管理系统。此系统可以完成录入身份证信息、查询身份证信息、修改和删除身份证信息；录入信息后可统计相关的(诸如一定年龄段的人数等)信息，并将信息存储在文件中。4） 技术方案： 建立身份证信息结构体链表； 对ID_card文件的打开、输入、关闭等操作； 对 ID_card 文件的读取、查找、统计等操作； 对身份证姓名、年龄、出生年月等校验和正误的判断； 用switch函数控制各子程序的调用； 程

9、序中应用指针、字符串、结构体嵌套、递归、函数调用等知识； 应用库函数strcpy、strcmp、stnrcmp、switch等。开始（欢迎界面）选择所需操作4.寻找信息2.添加信息1.创建新系统3.删除信息5.统计信息选择所需操作 选号符合规定选择所需统计操作选号符合规定选号符合规定按年龄查找按出生日期按姓名查找按年龄段按出生年份结束是是是否否否5） 身份证管理系统的框架图如下所示：6） 测试数据截屏：7） 详细设计说明 结构体：struct ID_card char name20;char sex;char nation10;int year;int month;int day;char a
