个人通讯录管理系统C语言源程序(优秀版)

使用C语言打造通讯录管理系统和教学安排系统的代码示例这篇文章主要介绍了使用C语言打造通讯录管理系统和教学安排系统的代码示例,利用C语言强大的数组和指针能够更加清晰地体现设计思路，需要的朋友可以参考下：通讯录管理系统实现了通讯录的录入信息、保存信息、插入、删除、排序、查找、单个显示等功能。

XXXX学院《C语言程序设计》课程设计报告学院:_XXXXXXXXX学院_ 专业班级: XXXXXXXXXX学生姓名: X X X 学号: XXXXXXXX设计地点（单位）________ XXX ______________ __设计题目:__________C语言个人通讯录管理系统 _________完成日期： 201X 年XX月XX日指导教师评语: ______________________ _________________ __________________________________________________________________________________ __________________________________________________________________________________ _____________________________________ __________ _成绩（五级记分制）:______ __________指导教师（签字）:________ ________摘要本次课程设计的题目为个人通讯录管理系统，要求将程序中所输入的联系人姓名、电话和地址信息这三个数据以文本方式保存在磁盘中，并且能够对所储存的联系人信息进行显示、查询、修改、删除等功能。

我编写的程序从整体上看可分为两个部分，一部分为文件的建立、读取和保存，另一部分为通讯录功能的实现。

在文件部分，我通过readfile()函数和writefile()函数从而实现了对磁盘上数据的进行写和读，通过刚开始的界面提示可以知道文件是否建立，以免丢失数据，我还为用户设计了保存退出和不保存退出两大功能供用户做选择。

在模块功能实现部分，通过scanf从键盘上输入的数字放到switch() case 循环中来实现调用zengjia()、shanchu()、xiugai()、chazhao()等十五个函数来实现“添加”、“查询和显示”、“修改”、“删除”等不同功能。
