通讯录管理系统c语言课程设计代码

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

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。

```C#include <stdio.h>#include <stdlib.h>#include <string.h>#define MAX_CONTACTS 100/* 定义联系人结构体 */struct contact {char name[50];char phone[20];char email[50];};/* 全局变量 */struct contact contacts[MAX_CONTACTS]; // 用于保存所有联系人int num_contacts = 0; // 当前联系人数量/* 函数声明 */void add_contact();void delete_contact();void search_contact();void list_contacts();int main() {int choice; // 用户选择的操作while (1) {printf("\n通讯录\n");printf("---------\n");printf("1. 添加联系人\n");printf("2. 删除联系人\n");printf("3. 查找联系人\n");printf("4. 列出所有联系人\n");printf("0. 退出\n");printf("请选择操作（0-4）：");scanf("%d", &choice);switch (choice) {case 0:printf("谢谢使用通讯录！\n"); exit(0);case 1:add_contact();break;case 2:delete_contact();break;case 3:search_contact();break;case 4:list_contacts();break;default:printf("无效的选择，请重试！\n"); }}return 0;}/* 添加联系人 */void add_contact() {struct contact new_contact;printf("请输入姓名：");scanf("%s", new_);printf("请输入电话号码：");scanf("%s", new_contact.phone);printf("请输入电子邮件：");scanf("%s", new_contact.email);contacts[num_contacts] = new_contact;num_contacts++;printf("联系人已添加！\n");}/* 删除联系人 */void delete_contact() {char name[50];int i, index = -1;printf("请输入要删除的联系人姓名："); scanf("%s", name);for (i = 0; i < num_contacts; i++) {if (strcmp(name, contacts[i].name) == 0) { index = i;break;}}if (index == -1) {printf("没有找到该联系人！\n");} else {for (i = index; i < num_contacts - 1; i++) { contacts[i] = contacts[i + 1];}num_contacts--;printf("联系人已删除！\n");}}/* 查找联系人 */void search_contact() {char name[50];int i, found = 0;printf("请输入要查找的联系人姓名：");scanf("%s", name);for (i = 0; i < num_contacts; i++) {if (strcmp(name, contacts[i].name) == 0) { printf("姓名：%s\n", contacts[i].name); printf("电话：%s\n", contacts[i].phone);printf("电子邮件：%s\n", contacts[i].email);found = 1;break;}}if (!found) {printf("没有找到该联系人！\n");}}/* 列出所有联系人 */void list_contacts() {int i;if (num_contacts == 0) {printf("通讯录为空！\n");} else {printf("所有联系人：\n");for (i = 0; i < num_contacts; i++) {printf("%d. 姓名：%s\t电话：%s\t电子邮件：%s\n", i + 1, contacts[i].name, contacts[i].phone, contacts[i].email);}}}```这个程序使用了结构体来表示联系人的信息，并通过全局数组来保存所有联系人。
