设计出模拟手机通信录管理系统，实现对手机中的通信录进行管理。基本功能: （1）查询功能：选择此功能时，可实现按姓名查询或按电话查询。（2）增加功能：能录入新数据（一个结点包括：姓名、电话号码、分类（可选项有：A 办公类 B 个人类 C 商务类）、电子邮件）。例如：张三 商务类 Chuny@126.C++om当录入了重复的姓名和电话号码时，则提示数据录入重复并取消录入；当通信录中超过15条信息时，存储空间已满，不能再录入新数据；录入的新数据能按递增的顺序自动进行条目编号。（4）修改功能：选中某个人的姓名时，可对此人的相应数据进行修改。（5）删除功能：选中某个人的姓名时，可对此人的相应数据进行删除，并自动调整后续条目的编号。

以下是一个简单的通讯录管理系统的实现示例，使用C++语言编写：

#include <iostream>
#include <string>
using namespace std;

// 定义通讯录节点结构体
struct ContactNode {
    int id; // 条目编号
    string name; // 姓名
    string phone; // 电话号码
    string category; // 分类
    string email; // 电子邮件
    ContactNode *next; // 下一个节点指针
};

// 定义通讯录类
class ContactList {
public:
    ContactList() {
        head = new ContactNode();
        head->next = NULL;
        size = 0;
    }
    ~ContactList() {
        ContactNode *p = head;
        while (p) {
            ContactNode *q = p->next;
            delete p;
            p = q;
        }
    }

    // 查询功能
    void search(string key, int mode) {
        ContactNode *p = head->next;
        bool found = false;
        while (p) {
            if ((mode == 1 && p->name == key) || (mode == 2 && p->phone == key)) {
                found = true;
                cout << "编号：" << p->id << endl;
                cout << "姓名：" << p->name << endl;
                cout << "电话：" << p->phone << endl;
                cout << "分类：" << p->category << endl;
                cout << "邮箱：" << p->email << endl << endl;
            }
            p = p->next;
        }
        if (!found) {
            cout << "未找到匹配记录！" << endl << endl;
        }
    }

    // 增加功能
    void add(string name, string phone, string category, string email) {
        // 判断是否已经存在相同的姓名或电话号码
        ContactNode *p = head->next;
        while (p) {
            if (p->name == name || p->phone == phone) {
                cout << "已存在相同姓名或电话号码，无法添加！" << endl << endl;
                return;
            }
            p = p->next;
        }

        // 判断是否超出存储空间
        if (size >= 15) {
            cout << "通讯录已满，无法添加新记录！" << endl << endl;
            return;
        }

        // 插入新节点
        p = head;
        while (p->next) {
            if (p->next->name > name) {
                break;
            }
            p = p->next;
        }
        ContactNode *newNode = new ContactNode();
        newNode->id = ++size;
        newNode->name = name;
        newNode->phone = phone;
        newNode->category = category;
        newNode->email = email;
        newNode->next = p->next;
        p->next = newNode;

        cout << "添加成功！" << endl;
        cout << "编号：" << newNode->id << endl;
        cout << "姓名：" << newNode->name << endl;
        cout << "电话：" << newNode->phone << endl;
        cout << "分类：" << newNode->category << endl;
        cout << "邮箱：" << newNode->email << endl << endl;
    }

    // 修改功能
    void modify(string name) {
        ContactNode *p = head->next;
        bool found = false;

        if (!found) {
            cout << "未找到匹配记录！" << endl << endl;
        }
    }

    // 删除功能
