C语言课程设计——通讯录软件源代码（完美版）通讯录完美版操作说明书编译环境:Visual C++ 6.0初始密码为:111111主菜单:选择编号进行相应的操作:选择“1”:输入编号:如“001”。
通讯录数据结构如下，只要输入的数据不超过允许的范围即可:struct callmember //定义数据结构{char code[8]; // 编号char name[20]; // 姓名char callnumber[16]; // 电话号码char address[30]; // 地址};输入完后“Enter”结束。
然后又回到“main menu”。
选择“2”显示通讯录信息，但此时刚输入的信息还没保存，选择“3”就可以将联系人信息保存在“通讯录.txt”文件中了，这个文件是自动生成的不需自己建立。
除此外还有查询、修改、删除功能。
当然功能有限，望有能之士加以修改，完善内容～本软件是一个值得收藏的软件，可以用于管理自己的通讯录～源程序:/***************************C语言课程设计*****************************//******************************************************************* **//******************************************************************* **//******************************************************************* **//***** 项目名称: 通讯录管理系统 *****/ /***** 作者: *****/ /*****专业: ***** *****/ /***** 班级: ***** *****/ /***** 学号: ********* *****//***** 指导老师: *****/ /***** 完成时间: 2010.7.12 *****/ /***** 联系电话: 150*******3 *****/ /***** 初始密码: 111111 *****//*********************************************************************/ /******************************************************************* **//******************************************************************* **//************************预处理***************************************/ #include<string.h> #include<stdio.h>#include<stdlib.h>#include<windows.h>#include<conio.h>#define N 301 //修改N的值，就可以改变记录个数，实际容纳人数为N-1 struct callmember //定义数据结构{char code[8];
