用C＋＋写一个小型通讯录管理系统

以下是一个用C++写的小型通讯录管理系统的示例：

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

#define MAX 1000

// 联系人结构体
struct Person {
    string m_Name;  // 姓名
    int m_Sex;      // 性别：1男2女
    int m_Age;      // 年龄
    string m_Phone; // 电话
    string m_Addr;  // 地址
};

// 通讯录结构体
struct Addressbooks {
    Person personArray[MAX]; // 通讯录中保存的联系人数组
    int m_Size;              // 通讯录中当前记录的联系人数量
};

// 添加联系人
void addPerson(Addressbooks& abs) {
    if (abs.m_Size == MAX) {
        cout << "通讯录已满，无法添加！" << endl;
        return;
    }

    string name;
    cout << "请输入姓名：";
    cin >> name;
    abs.personArray[abs.m_Size].m_Name = name;

    int sex;
    cout << "请输入性别：1男 2女：";
    while (true) {
        cin >> sex;
        if (sex == 1 || sex == 2) {
            abs.personArray[abs.m_Size].m_Sex = sex;
            break;
        } else {
            cout << "输入有误，请重新输入：";
        }
    }

    int age;
    cout << "请输入年龄：";
    cin >> age;
    abs.personArray[abs.m_Size].m_Age = age;

    string phone;
    cout << "请输入电话：";
    cin >> phone;
    abs.personArray[abs.m_Size].m_Phone = phone;

    string addr;
    cout << "请输入地址：";
    cin >> addr;
    abs.personArray[abs.m_Size].m_Addr = addr;

    abs.m_Size++;
    cout << "联系人添加成功！" << endl;
}

// 显示所有联系人
void showPerson(Addressbooks& abs) {
    if (abs.m_Size == 0) {
        cout << "通讯录为空！" << endl;
        return;
    }

    for (int i = 0; i < abs.m_Size; i++) {
        cout << "姓名：" << abs.personArray[i].m_Name << "\t";
        cout << "性别：" << (abs.personArray[i].m_Sex == 1 ? "男" : "女") << "\t";
        cout << "年龄：" << abs.personArray[i].m_Age << "\t";
        cout << "电话：" << abs.personArray[i].m_Phone << "\t";
        cout << "地址：" << abs.personArray[i].m_Addr << endl;
    }
}

int main() {
    Addressbooks abs;
    abs.m_Size = 0;

    while (true) {
        cout << "***************************" << endl;
        cout << "***** 1.添加联系人 *******" << endl;
        cout << "***** 2.显示联系人 *******" << endl;
        cout << "***** 3.退出通讯录 *******" << endl;
        cout << "***************************" << endl;

        int select;
        cout << "请选择操作：";
        cin >> select;

        switch (select) {
            case 1:  // 添加联系人
                addPerson(abs);
                break;
            case 2:  // 显示联系人
                showPerson(abs);
                break;
            case 3:  // 退出通讯录
                cout << "欢迎下次使用！" << endl;
                return 0;
            default:
                cout << "输入有误，请重新选择！" << endl;
                break;
        }
    }

    return 0;
}
