Question

C++. here is the problem that kind of the same with the example that i did in class (attach picture). however, this require use the loop to do, I get confuse. pls help me! thank you!

Problem: Define a class to implement the time of day in a program. To represent time, use three member variables: one to represent the hours, one to represent the minutes, and one to represent the seconds. Also define the following member functions in the class: • Input the time. • Print the time. • Increment the time by one second. . Increment the time by one minute. • Increment the time by one hour. • Compare the two times for equality. In the main, declare array of the class type of size 4 and test all of the member functions. Write comments.

$DayOfYear today, birthday; cout << Enter todays date:\n; cout << Enter month as a number: ; cin >> today.month; cout <<$

======================== c++ code of the time class with given specification =============

#include <iostream>
#include<iomanip>
using namespace std;
class Time //class representing time
{
private :
int hour;
int minute;
int second;
public :
// default constructor with default value
Time(int h = 0, int m = 0, int s = 0);
//input function
void inputTime(int h, int m, int s);
//display time in hh:mm:ss
void display();
//check equality of 0 or 1 two time object
bool compare(Time);
void incrementBy1Second(); // incrementBy1Second
void incrementBy1Minute();// incrementBy1Minute
void incrementBy1hour();// incrementBy1hour
  
};

Time :: Time(int h, int m, int s)
{
hour = h;
minute = m;
second = s;
}

void Time :: inputTime(int h, int m, int s)
{
hour = h;
minute = m;
second = s;   
}

void Time :: display()
{
cout << setw(2) << setfill('0') << hour << ":"
<< setw(2) << setfill('0') << minute << ":"
<< setw(2) << setfill('0') << second << "\n";
}

bool Time :: compare(Time otherTime)
{
if(hour == otherTime.hour &&
minute == otherTime.minute &&
second == otherTime.second)
return true;
else
return false;
}
void Time :: incrementBy1Second()
{
if(second<60)
{
second+=1;
}
else if(second==60)
{

{

}
}
}
  
}

void Time :: incrementBy1Minute()
{

{
minute+=1;
  
}
else if(minute==60)
{
if(hour<23)
{

}

}
}
  
}

void Time :: incrementBy1hour()
{
if(hour<23)
{

}
else
{

}
}

int main()
{

bool result = t[1].compare(t[0]);
cout<<"result of comapre"<<result;
  
  
  
return 0;
}
