C++簡單實現通訊錄管理系統

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

//聯系人結構體
struct Person {
	string M_name; 		//姓名
	int M_sex;			//性別:1男 2女
	int M_age;			//年齡
	string M_phone;		//電話
	string M_address;		//地址
};

//通訊錄結構體
struct Addressbooks {
	struct Person personArray[MAX];	//通訊錄中保持的聯系人數組
	int M_size;						//通訊錄中人員個數
};
