C++实现通讯录

简介：通讯录由一个拥有者以及通讯信息组成。

基本功能：增删改查

拥有者和通讯信息的基础结构相同，由struct构成

struct Person {
	int m_id;
	string m_name;
	string m_tele;//手机号码可以作为id，但是过于长（11位）
	//string m_addr;

	Person& operator = (const Person& r) {
		if (this == &r) return *this;
		m_id = r.m_id;
		m_name = r.m_name;
		m_tele = r.m_tele;
		return *this;
	}
};

Person：id+姓名+手机号。还可以添加需要的信息，例如：地址、性别

重载了一个=操作符

通讯录建立class AddressList

class AddressList {
private:
	Person owner;//通讯录拥有者
	vector<Person> information;//通讯录：好友的信息组成
public:
	AddressList();
	AddressList(const Person&, const vector<Person>& info = {});
	AddressList(const AddressList&);

	void Add(const Person&);//添加一个好友信息至通讯录
	void Delete();//通过姓名删除
		      //通过电话号码删除
	void Modify();//输入id 修改姓名and号码
	void Search(int);//1:id搜索
			 //2：姓名搜索
			 //3：号码指定搜索
	void Print()const;
	//查看通讯录所有信息：仅显示id和姓名，详细信息输入id查看	
};

cpp：

#include "AddressList.h"
#include <iostream>
using namespace std;

AddressList::AddressList() {}

AddressList::AddressList(const Person& r, const vector<Person>& info) {
	owner = r;

	}
}

	//添加一个好友信息至通讯录
	//首先确认不存在：id+tele
	for (const auto& it : information) {

			cout << "Id已存在，添加失败!\n";
			return;
