C语言课程设计——通讯录软件源代码(完美版)

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];

c语言学生通讯录设计

下面是一个简单的C语言学生通讯录设计示例：#include <stdio.h>#include <string.h>struct student {char name[20];int age;char gender;char phone[15];};int main() {struct student students[100];int n, i;printf("请输入学生人数：");scanf("%d", &n);for (i = 0; i < n; i++) {printf("请输入第%d个学生的姓名、年龄、性别和电话号码：", i+1);scanf("%s %d %c %s", students[i].name, &students[i].age, &students[i].gender, students[i].phone);}printf("\n学生通讯录\n");printf("姓名\t年龄\t性别\t电话号码\n");for (i = 0; i < n; i++) {printf("%s\t%d\t%c\t%s\n", students[i].name, students[i].age, students[i].gender, students[i].phone);}return 0;}该程序定义了一个名为`student`的结构体，用于存储学生的姓名、年龄、性别和电话号码。

在主函数中，首先通过`scanf`函数从用户输入中读取学生人数`n`，然后使用一个循环来依次读取每个学生的信息，并将它们存储到`students`数组中。

最后，使用另一个循环将所有学生的信息打印出来。

该程序可以根据需要添加其他功能，例如根据姓名或电话号码查询学生信息、添加或删除学生信息等。

(完整word版)c语言程序设计通讯录管理系统

1.需求分析根据题目要求，通讯录保存在文件中，要提供文件的输入和输出功能；还有就是要提供通讯录添加（个人信息包括姓名、学号、年龄、住址、电子邮件等)、删除、显示、修改等基本功能。

2。

概要设计系统总体设计是信息的输入、信息的编辑和退出.系统功能模块如下:1.添加通讯录；2.输出通讯录；3.查找通讯录；4.修改通讯录；5.删除通讯录；6.退出通讯录；3.详细设计1.通讯录里无信息，所以要添加信息.用键盘逐个输入通讯录里联系人的信息.2.输出通讯录用于让使用者观看通讯录里所有的信息.3。

查找通讯录是让使用者可以通过电话或姓名来查找通讯录里的联系人.4。

修改通讯录是让使用者通过姓名查找到通讯录里的联系人，然后其作出修改。

5.删除通讯录是用来按照联系人的姓名或电话来单独删除通讯录中一些不想要的联系人。

还可以集体删除通讯录中的联系人.6.退出通讯录系统。

4.主要源程序代码＃include 〈stdio。
