C++项目：通讯录管理系统

项目目标：

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、清空通讯录

自编头文件：

#pragma once
#include
#include
using namespace std;
#define MAX 1000
#define fm(a) (a)==1?"男":"女"
struct Person
{
	string Name;
	int sex;
	int Age;
	string Phone;
	string Addr;

int isExist(AddressBooks* abs, string name);
void DeletePerson(AddressBooks* abs);
void findPerson(AddressBooks* abs);
