C语言课程设计-身份 管理系统报告

1、 题 目 身份证管理系统学 号姓 名年级专业09电子信息工程指导教师完成日期2010年06月22日身份证管理系统一、课程设计的目的进一步掌握和利用C语言进行程设计的能力，理解和运用结构化程设计的思想和方法，熟练掌握条件语句、循环、数组、结构体、函数操作，初步掌握开发一个小型实用系统的基本方法，学会高度一个较长程序的基本方法和利用流程图或N-S图表示算法，将本课程所学的知识合理地运用于实践当中。了解一些书上没有的函数及使用方法。二、设计方案论证1设计思路 利用数组对每个人的记录进行循环输入输出，利用冒泡法记录进行排序，利用循环查找数组中某个数据，对其进行输入，显示，插入，删除，查找，统计，读入和

2、写入文档等操作。2分工我主要负责程序的后半段编写和最终程序的调试、运行；尹仁超主要负责程序的主体的编写，其中也经历了相互的讨论等。3.流程图开始输出界面选择操作选择1选择2选择3选择4选择5选择6选择7选择8选择9选择0输入记录是是显示记录否否否否否否否否否退出系统结束按生日排序显示插入一个记录是是是是删除一个记录查找一个记录统计某年龄人数从文件输入写入文件保存是是是是否4具体程序#include#include#includetypedef struct char name20; char sex5; char folk5; char birth10; char add20; char id
