C ++文字游戏自定义时钟系统

Question

Clock doesn't work. Once it reaches 60 mins, it continues onward without changing hour. Example: 12:75 am, 12:90 am, etc... I wanted to build a clock that adds time based on actions. Does not work on real time.

Sorry for the mess, new to Stack Overflow, and sharing code in general. Keep in mind, I'm still new to coding.

(All integers used)
-
int timeHour = 0;
string timePMAM = "";
int timeHourDisplay = 0;
int timeHourMax = 12;

int timeMin = 0;
int timeMinDisplay = 00;

int day = 0;
string dayDisplay = "";
if (timeMin == 60)
    {
        timeMinDisplay = 0;
        timeMin = 0;
        timeHour += 1;
        timeHourDisplay += 1;
    }
    if (timeMin > 60)
    {
        timeMinDisplay -= 60;
        timeMin -= 60;
        timeHour += 1;
        timeHourDisplay += 1;
    }
    //Used for changing 60minutes into an hour

    if (timeHour < timeHourMax)
    {
        timePMAM = "am";
    }
    if (timeHour >= timeHourMax)
    {
        timePMAM = "pm";
    }
    //pm and am

    if (timeHour == 13)
    {
        timeHourDisplay = 1;
    }
    // 13 o'clock is now 1 o'clock
    if (timeHour == 24)
    {
        timeHour = 0;
        timeHourDisplay = 12;
        day += 1;
    }
    if (timeHour == 1)
    {
        timeHourDisplay = 1;
    }
    if (timeHour == 0)
    {
        timeHourDisplay = 12;
    }
}

I recommend using Howard Hinnant's free, open source date/time library . It takes care of all of the time/calendrical arithmetic for you and has very flexible formatting options. For example:

#include "date.h"
#include <iostream>
#include <string>

std::string
display_time(std::chrono::system_clock::time_point time)
{
    auto s = date::format("%I:%M %p", time);
    if (s.front() == '0')
        s.erase(0, 1);
    for (auto& c : s)
        c = tolower(c);
    return s;
}

std::string
display_date(std::chrono::system_clock::time_point time)
{
    return date::format("%b %e, %Y", time);
}

int
main()
{
    using namespace std;
    using namespace date::literals;
    auto time = date::sys_days{2017_y/sep/10} + 75min;

    time += 15min;
    cout << "The walk took 15 minutes: " << display_time(time) << '\n';

    cout << "You lay down on the cold ground and cry yourself to sleep, longing for burrito" << endl;
    time += 8h;
    cout << display_time(time) << endl;

    cout << "The current time is " << display_time(time) << endl;
            cout << "The date is " << display_date(time) << endl;
            cout << "It seems your watch is broken again.." << endl;
}

Output:

The walk took 15 minutes: 1:30 am
You lay down on the cold ground and cry yourself to sleep, longing for burrito
9:30 am
The current time is 9:30 am
The date is Sep 10, 2017
It seems your watch is broken again..
