通讯录管理系统C语言课程设计代码
一、引言
在现代社会中，通讯方式多样化且频繁，通讯录管理系统应运而生。
本文将介
绍一个基于C语言设计的通讯录管理系统的代码实现。
通讯录管理系统可以帮助
用户有效地管理联系人信息，实现增删改查等操作。
二、系统功能设计
通讯录管理系统主要包括以下功能： 1. 添加联系人：用户可以输入联系人姓名、电话号码等信息，将联系人信息添加到通讯录中。
2. 删除联系人：用户可以根据
姓名或电话号码删除指定联系人信息。
3. 修改联系人：用户可以修改已有联系人
的信息，包括姓名、电话号码等。
4. 查询联系人：用户可以根据姓名或电话号码
查询联系人信息。
5. 显示所有联系人：用户可以查看通讯录中所有联系人的信息。
三、代码实现
```c #include <stdio.h> #include <string.h>
#define MAX_CONTACTS 100 #define MAX_NAME_LENGTH 50 #define
MAX_PHONE_LENGTH 15
struct Contact { char name[MAX_NAME_LENGTH]; char
phone[MAX_PHONE_LENGTH]; };
struct Contact contacts[MAX_CONTACTS]; int numContacts = 0;
void addContact() { if (numContacts < MAX_CONTACTS) { printf(。

c语言中通讯录代码以下是一个简单的C语言实现通讯录的代码。
这个程序可以添加，删除和查找联系人，以及列出所有联系人的信息。

一、课程设计题目及要求题目通讯录管理系统任务：自学C语言中相关知识，设计出通讯录管理系统。
要求如下所述：◆建立通讯录信息，信息至少包含编号、姓名、年龄、电话、通讯地址、电子邮箱等；；◆能够提供添加、删除和修改通讯录信息的功能；◆能够提供按姓名或电话等查询；◆将通讯录保存在文件中；◆能够按表格方式输出通讯录信息。
二、系统设计方案（一）总体框架图：通讯录管理系统：1、录入通讯录信息2、修改通讯录信息3、查询通讯录信息4、浏览通讯录信息5、增加通讯录信息6、推出系通讯录统（二）模块设计模块一：头文件，变量定义，函数的声明对系统所使用的变量进行定义，对函数进行声明模块二：录入通讯录信息声明函数void readfile()，说明一个文件指针FILE *fp 打开文件"student.txt"模块三：通讯录信息的查找声明void seek()为查找函数，通过switch(item)设定用学号查找，用姓名查找两个分支模块四：通讯录信息的修改声明void modify()为学生信息修改函数，通过switch(item)设定所要修改的项目模块五：通讯录信息按学号排序声明void sort()将录入通讯录信息系按升序排列，用的是“冒泡排序法”实现排序模块六：加通讯录信息声明void insert()插入通讯录信息，先通过判断通讯录是否存在，若否则继续输入，若是跳出，重新循环模块七：通讯录信息声明void del()实现通讯录信息删除，通过学号对比确定要删除的信息，然后用后一个替换掉。
模块八：示学生信息通过display()函数输出通讯录信息模块九;存信息通过fp=fopen("student.txt","w");写入信息模块十：界面菜单通过switch(num)调用，以上各函数，实现功能三、设计详情1.主函数主函数设计要求简洁，只提供部分提示语和函数的调用【程序】图1. 主函数流程图void menu()/* 界面*/{ int num;printf(" \n\n 自动化0901通讯录管理系统\n\n");printf(" ***************** \n\n");printf(" * 制作人:翁行兴* \n \n");printf(" ***************** \n\n");printf("*********************系统功能菜单************************ \n");printf(" ---------------------- ---------------------- \n");printf(" * 1.刷新学生信息* * 2.查询学生信息* \n");printf(" * 3.修改学生信息* * 4.增加学生信息* \n");printf(" * 5.按学号删除信息* * 6.显示当前信息* \n");printf(" * 7.保存当前学生信息* * 8.退出系统* \n");printf(" ---------------------- ---------------------- \n");printf("请选择菜单编号:");scanf("%d",&num);switch(num){case 1:readfile();break;case 2:seek();break;case 3:modify();break;case 4:insert();break;case 5:del();break;case 6:display();break;case 7:save();break;case 8:k=0;break;default:printf("请在1-8之间选择\n");}}四、源代码#include<stdio.h>#include<stdlib.h>#include<string.h>#define BUFLEN 100#define LEN 15#define N 100struct record /*结构体*/{char code[LEN+1]; /* 学号*/char name[LEN+1]; /* 姓名*/int age; /* 年龄*/char sex[3]; /* 性别*/char time[LEN+1]; /* 出生年月*/ char add[30]; /* 家庭地址*/char tel[LEN+1]; /* 电话号码*/char mail[30]; /* 电子邮件地址*/ }stu[N];int k=1,n,m; /* 定义全局变量*/ void readfile();/* 函数声明*/void seek();void modify();void insert();void del();void display();void save();void menu();int main(){while(k)menu();system("pause");return 0;}void readfile()/* 建立信息*/{char *p="student.txt";FILE *fp;int i=0;if ((fp=fopen("student.txt","r"))==NULL){printf("Open file %s error!
