#include <iostream>        //头文件别漏了哦
using namespace std;

class date {
private:
    int year;
    int month;
    int day;

public:
    //添加一个默认构造函数
    date() {
        year = 2022;
        month = 01;
        day = 01;
    }
    date(int myear, int mmonth, int mday) {
        year = myear;
        month = mmonth;
        day = mday;
    }

    void setyear(int myear) {
        year = myear;
    }
    int getyear() {
        return year;
    }
    void deyear() {
        cout << year << endl;

    int getday() {
        return day;
    }
    void deday() {
        cout << day << endl;
    }

    //定义一个show函数来输出信息
    void show() {
        cout << this->year << "." << this->month << "." << this->day << endl;
    }
};

class people {

    }

    void setphone(int mphone) {
        phone = mphone;
    }
    int getphone() {
        return phone;
    }
    void dephone() {
        cout << phone << endl;
    }

    void setname(int mname) {
        name = mname;
    }
    string getname() {
        return name;
    }
    void deneme() {

    }

    void setdone(int mdone) {
        done = mdone;
    }
    int getdone() {
        return done;
    }
    void dedone() {
        cout << done << endl;
    }

    void settime(date mtime) {
        time = mtime;
    }
    date gettime() {
        return time;
    }
    void detime() {
        //改为用函数输出信息
        time.show();
    }

    void setresult(int mresult) {
        result = mresult;
    }
    bool getresult() {

改好了，解释写在注释里，有什么问题可以随时问我
