}

添加联系人

设计联系人结构体
设计通讯录结构体
初始化通讯录
判断通讯录是否为满

//联系人结构体
struct Person
{
    //姓名
    string name;

    //性别：1男 2女
    int m_Sex;

    //年龄
    int m_Age;

    //电话
    string m_Phone;

    //住址
    string m_Addr;
};



//通讯录结构体
struct Addressbooks
{
    //通讯录中保存的结构体数组
    Person personArray[1000];

    //通讯录中人数的个数
    int m_Size;
};

//添加联系人
void Addperson(Addressbooks *abs)
{
    //判断通讯录是否为满
    if(abs->m_Size == 1000 )
    {
        cout << "通讯录已满" << endl;
        return;
    }

    else
    {
        //添加姓名
        string name;
        cout << "请输入要添加的名字" << endl;
        cin >> name;
        abs->personArray[abs->m_Size].name = name;


        //添加性别
        cout << "请输入性别" << endl;
        cout <<"1---男" << endl;
        cout << "2---女" << endl;
        int sex = 0;
        while (true)
        {
            cin >> sex;
                if(sex == 1 || sex ==2)
                {
                    abs->personArray[abs->m_Size].m_Sex = sex;
                    break;
                }
            cout << "你输入的性别有错误，请重新输入" << endl;
        }
        
        
        //添加年龄
        cout << "请输入年龄"<< endl;
        int age;
        cin >> age;
        abs->personArray[abs->m_Size].m_Age = age;

        //添加地址
        cout << "请输入地址" << endl;
        string address;
        cin >> address;
        abs->personArray[abs->m_Size].m_Addr = address;

        //添加电话
        cout << "请输入联系电话" << endl;
        string phone;
        cin >> phone;
        abs->personArray[abs->m_Size].m_Phone = phone;

        //更新通讯录人数
        abs->m_Size++;

        //提醒用户添加成功
        cout << "添加成功" << endl;

        system("pause");
        system("cls");
    }

}

显示联系人

判断是否为空
遍历显示

void showPerson(Addressbooks *abs)
{
    //判断通讯录是否为空
    if (abs->m_Size == 0)
    {
        cout << "当前记录为空" << endl;

    }
    else
    {
        for (int  i = 0; i < abs->m_Size; i++)
        {
            cout << "姓名：" << abs->personArray[i].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 << "住址：" << abs->personArray[i].m_Addr << endl;
        }
        
    }
    

}

删除联系人

判断联系人是否存在
若存在则后面一个覆盖前面一个

//检测联系人是否存在
int isExit(Addressbooks *abs,string name)
{
    for (int i = 0; i < abs->m_Size; i++)
    {
        if(abs->personArray[i].name == name)
        {
            return i;//返回该联系人的下标
        }
    }
    
    return -1;
}


//删除联系人
void delectPerson(Addressbooks *abs)
{
    string name;
    cin >> name;
    //判断这个人是否存在
    int rev = isExit(abs,name);
    if (rev != -1)
    {
        for ( int i = rev; i < abs->m_Size; i++)
        {
            abs->personArray[i] = abs->personArray[i+1];
        }
        abs->m_Size--;
        cout << "删除成功" << endl;
    }
    
    else
    {
        cout << "此人不存在" << endl;
    }
}

查找联系人

判断该联系人是否存在
存在则显示出他的全部信息

//查找联系人
void findPerson(Addressbooks *abs)
{
    cout << "请输入你要查找的人联系人" << endl;
    string name;
    cin >> name;
    
    //判断该联系人是否存在
    int rev = isExit(abs,name);
    if(rev != -1)
    {
        cout << "姓名：" << abs->personArray[rev].name << "\t";
        cout << "性别 ："<< (abs->personArray[rev].m_Sex == 1 ? "男":"女") << "\t";
        cout << "年龄：" << abs->personArray[rev].m_Age << "\t";
        cout << "电话：" << abs->personArray[rev].m_Phone << "\t";
        cout << "住址：" << abs->personArray[rev].m_Addr << endl;
    }
    else
    {
        cout << "此人不存在" << endl;
    }
}

修改联系人

判断该联系人是否存在
存在则修改

//修改联系人
void modifyPerson(Addressbooks *abs)
{
    
    cout << "请输入你要修改的人联系人名字" << endl;
    string name;
    cin >> name;
    
    //判断该联系人是否存在
    int rev = isExit(abs,name);
    if(rev != -1)
    {
         //添加姓名
        string name;
        cout << "请输入要修改的名字" << endl;
        cin >> name;
        abs->personArray[rev].name = name;

        cout << "请输入性别" << endl;
        cout <<"1---男" << endl;
        cout << "2---女" << endl;
        int sex = 0;
        while (true)
        {
            cin >> sex;
                if(sex == 1 || sex ==2)
                {
                    abs->personArray[rev].m_Sex = sex;
                    break;
                }
            cout << "你输入的性别有错误，请重新输入" << endl;
        }
        
        
        //添加年龄
        cout << "请输入年龄"<< endl;
        int age;
        cin >> age;
        abs->personArray[rev].m_Age = age;

        //添加地址
        cout << "请输入地址" << endl;
        string address;
        cin >> address;
        abs->personArray[rev].m_Addr = address;

        //添加电话
        cout << "请输入联系电话" << endl;
        string phone;
        cin >> phone;
        abs->personArray[rev].m_Phone = phone;


        //提醒用户添加成功
        cout << "修改成功" << endl;
    }
    else
    {
        cout << "此人不存在" << endl;
    }
}

清空联系人

//清空联系人
void cleanPerson(Addressbooks *abs)
{
    abs->m_Size = 0;
    cout << "通讯录已经清空" << endl;
}
