用中文注释一下C++这个程序

# include<iostream>
# include<ctime>
using namespace std;
struct DepartureDate
{
    int year;
    int month;
    int day;
};

struct DepartureTime
{
    int hour;
    int minute;
};

struct Ticket
{
    string passengerName;//乘客姓名
    DepartureDate departureDate;//出发日期
    DepartureTime departureTime;//出发时间
    int fromCityID;//始发站
    int toCityID;//终点站
    string passengerID;//身份证号
    int carID;//车厢号6
    char seatID[4];//座位号C06
    char trainID[6];//车次D2509
    char seatType;//座别，a：商务座、b:一等座、c二等座
    char checkPort[4];//检票口A11
    double ticketPrice;
    int ticketID;

};

bool Refund(int ticketId);//退票
Ticket BookTicket(string name, int cityId, char seatType);//订票
bool ChangeSeatType(Ticket& ticket, char seatType);//更改座位类型

int main()
{
    Ticket ticket;
    char name[100];
    int cityId;
    char seatType;
    cout << "购票中......" << endl;
    cout << "请输入姓名" << endl;
    cin >> name;
    cout << "请输入目的地城市：0-北京，1-上海，2-大连" << endl;
    cin >> cityId;
    cout << "请输入座位类型：a-商务座、b-一等座、c-二等座" << endl;
    cin >> seatType;
    ticket=BookTicket(name,cityId,seatType);
    cout << "订票完成" << ticket.ticketID << endl;

}
//订票
Ticket BookTicket(string name, int cityId, char seatType)
{
    Ticket ticket = {};
    strcpy(ticket.checkPort, "A11");
    ticket.toCityID = cityId;
    ticket.passengerName = name;
    ticket.departureDate = { 2020,12,25 };
    ticket.departureTime = { 4,15 };
    ticket.seatType = seatType;
    strcpy(ticket.trainID, "D2509");
    ticket.ticketPrice = 237.5;
    strcpy(ticket.seatID, "A06");
    srand((int)time(0));
    ticket.ticketID = rand() % 100;;
    return ticket;

}
//退票
bool Refund(int ticketId)
{
    return false;
}
//修改座位类型
bool ChangeSeatType(Ticket& ticket, char seatType)
{
    ticket.seatType = seatType;
    return true;
}

这个程序比较简单啊，你具体哪里看不懂啊，还是一句都看不懂？这决定注释要写到什么程度才适合你啊
