C++ Program to Calculate Difference Between Two Time Period

C++ProgrammingServer Side Programming

There are two time periods provided in the form of hours, minutes and seconds. Then their difference is calculated. For example −

Time period 1 = 8:6:2
Time period 2 = 3:9:3
Time Difference is 4:56:59

A program that calculates the difference between two time periods is given as follows −

Example

 Live Demo

#include <iostream>
using namespace std;
int main() {
   int hour1, minute1, second1;
   int hour2, minute2, second2;
   int diff_hour, diff_minute, diff_second;

   cout << "Enter time period 1" << endl;
   cout << "Enter hours, minutes and seconds respectively: "<< endl;
   cin >> hour1 >> minute1 >> second1;

   cout << "Enter time period 2" << endl;
   cout << "Enter hours, minutes and seconds respectively: "<< endl;
   cin >> hour2 >> minute2 >> second2;

   if(second2 > second1) {
      minute1--;
      second1 += 60;
   }

   diff_second = second1 - second2;

   if(minute2 > minute1) {
      hour1--;
      minute1 += 60;
   }
   diff_minute = minute1 - minute2;
   diff_hour = hour1 - hour2;

   cout <<"Time Difference is "<< diff_hour <<":"<< diff_minute <<":"<<diff_second;

   return 0;
}

Output

The output of the above program is as follows −

Enter time period 1
Enter hours, minutes and seconds respectively: 7 6 2

Enter time period 2
Enter hours, minutes and seconds respectively: 5 4 3

Time Difference is 2:1:59

In the above program, two time periods are accepted from the user in the form of hours, minutes and seconds. This is given below −

cout << "Enter time period 1" << endl;
cout << "Enter hours, minutes and seconds respectively: "<< endl;
cin >> hour1 >> minute1 >> second1;

cout << "Enter time period 2" << endl;
cout << "Enter hours, minutes and seconds respectively: "<< endl;
cin >> hour2 >> minute2 >> second2;

Then the difference between these two time periods is calculated using the method provided in the following code snippet −

if(second2 > second1) {
   minute1--;
   second1 += 60;
}
diff_second = second1 - second2;
if(minute2 > minute1) {
   hour1--;
   minute1 += 60;
}
diff_minute = minute1 - minute2;
diff_hour = hour1 - hour2;

Finally the time difference is displayed. This is given below −

cout <<"Time Difference is "<< diff_hour <<":"<< diff_minute <<":"<<diff_second;
