用c++写一个通讯录管理系统

好的，我可以回答这个问题。通讯录管理系统可以使用C语言来实现。首先，需要定义一个结构体来存储联系人的信息，包括姓名、电话号码、邮箱等。然后，可以使用链表来存储所有联系人的信息，并提供添加、删除、查找、修改等功能。具体实现可以参考C语言的链表操作。另外，还可以实现一些高级功能，比如导入/导出联系人信息、按照姓名/电话号码排序等。

C++写一个通讯录管理系统

好的，我来为您提供一个简单的通讯录管理系统的C++代码，该代码包括添加联系人、显示联系人、删除联系人、查找联系人和修改联系人等功能。

#include <iostream>
#include <string>

// 定义联系人结构体
struct Person
{
    string name;    // 姓名
    int age;        // 年龄
    string phone;   // 电话
