一、代码

//封装函数显示该界面，在main函数中调用这个封装函数
#include<iostream>
#include<string>
#define MAX 1000
using namespace std;

//设计联系人的结构体 名字 性别 年龄 电话 住址
struct People {
	//创建名字
	string Pname;
	//创建性别 输入1为男 输入2为女
	int Psex;
	//创建年龄
	int Page;
	//创建手机号码
	string Ptele;
	//创建地址
	string Pdress;

//设计通讯录的结构体 通讯录的容量为1000
struct Abooks {
	//通讯录中保存的联系人的数组
	struct People Parry[MAX];
	//记录通讯录中的总人数
	int Asize;

//功能2.显示联系人
void Showpeople(Abooks* abs)

				 << "性别为：" << (abs->Parry[i].Psex == 1 ? "男" : "女") << "\t"

//功能四的输出函数

二、总结

system(“cls”); 清屏操作会让程序运行起来更加美观
弄清指针关系
