C++ 个人通讯录管理系统（五）

在此，将整个系统的代码输出：

#include <iostream>
#include <string>

using namespace std;

#define MAX 1000 //最大人数

//菜单界面
void showMenu()
{
	cout << "***************************" << endl;
	cout << "*****  1、添加联系人  *****" << endl;
	cout << "*****  2、显示联系人  *****" << endl;
	cout << "*****  3、删除联系人  *****" << endl;
	cout << "*****  4、查找联系人  *****" << endl;
	cout << "*****  5、修改联系人  *****" << endl;
	cout << "*****  6、清空联系人  *****" << endl;
	cout << "*****  0、退出通讯录  *****" << endl;
	cout << "***************************" << endl;
}

};

//设计通讯录结构体

};

//1. 添加联系人信息
