代码如下：

#include <iostream>
    using namespace std;
    #include <string>
    #define Max 1000 //最大人数
    // 设计联系人结构体
    struct Person {
    	//姓名
    	string m_Name;
    	//性别 1男 2 女
    	int m_Sex;
    	//年龄
    	int m_Age;
    	//电话
    	string m_Phone;
    	//住址
    	string m_Address;
    };
    // 设计通讯录结构体
    struct Addressbooks {
    	//通讯录中保存的联系人数组
    	struct Person personArray[Max];
    	//通讯录中当前记录联系人个数
    	int m_Size;
    };
