linux环境下c++实现通讯录系统

通讯录系统

该系统具有下面7种操作：

---

***** 1、添加联系人*****

***** 2、显示联系人*****

***** 3、删除联系人*****

***** 4、查找联系人*****

***** 5、修改联系人*****

***** 6、清空联系人*****

***** 0、退出通讯录 ****

---

源代码如下：

/*
封装函数显示界面，如void showMenu()
*/

#include<iostream>
#include <unistd.h>
#include <string>
using namespace std;
#define MAX 1000

//联系人结构体

    string m_Name;

    int m_Age;
    string m_Phone;
    string m_Addr;
};


//通讯录结构体
struct Addressbooks{

    Person personArray [MAX];
    int m_Size;//通讯录中人员个数
};

//1.添加联系人
