C++怎么实现简易通讯录

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

// 设计联系人的结构体
struct Person 
{
 string m_Name;
 int m_Sex;  // 1、男  2 女
 int m_Age;
 string m_Phone;
 string m_Addr;
};

// 设计通讯录的结构体
struct Addressbooks
{
 struct Person personArray[MAX];
 int m_Size;
};


// 1、菜单界面
void showMenu()
{
 cout << "***************************" << endl;
 cout << "***** 1、添加联系人 *****" << endl;

 cout << "***** 6、清空联系人 *****" << endl;
 cout << "***** 0、退出通讯录 *****" << endl;
 cout << "***************************" << endl;

// 2、添加联系人
void addPerson(Addressbooks * abs)
