简单实现通讯录功能说明

实现语言c++,简单结构体训练，穿插一些简单算法思想。

编写通讯录

实现添加，展示，删除，查找，修改，清空，退出系统

c++代码如下

#include <iostream>
#include <string>
using namespace std;
#define max 1000 
//联系人的结构体 
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;
	//地址 
	string m_address ;

};

struct addressbooks{
	//通讯录的保存联系人数据
	struct person presonarray[max];
	//通讯录当前联系人个数
	int  m_size;
	 
};
void cleanperson(addressbooks *abs);
void showperson(addressbooks *abs);
void addperson(addressbooks *abs);
int isexist(addressbooks *abs,string name);
void deleteperson(addressbooks *abs);
void show1();
void findperson(addressbooks *abs);
void modifperson(addressbooks *abs);
int main()
{   int choice = 1;
    addressbooks abs;
    abs.m_size=0;
	while(choice)
