Program to check Time Difference in CPP (C plus plus)

In this tutorial, we will learn about the Program to check Time Difference in CPP (C plus plus).

#include <iostream>

using namespace std;

struct time
{
  int hrs; 
  int mins;
  int secs;
};

void computeTimeDifference(struct time, struct time, struct time *);

int main()
{
    struct time t1, t2, difference;

    cout << "Please enter Starting Time: " << endl;
    cout << "Please enter Hours, Minutes & Seconds respectively: ";
    cin >> t1.hrs >> t1.mins >> t1.secs;

    cout <<endl<< "Please enter Stop Time: " << endl;
    cout << "Please enter Hours, Minutes & Seconds respectively: ";
    cin >> t2.hrs >> t2.mins >> t2.secs;

    computeTimeDifference(t1, t2, &difference);

    cout << endl << "*Time Difference*: " << t1.hrs << ":" << t1.mins << ":" << t1.secs;
    cout << " - " << t2.hrs << ":" << t2.mins << ":" << t2.secs;
    cout << " = " << difference.hrs << ":" << difference.mins << ":" << difference.secs;
    return 0;
}
void computeTimeDifference(struct time t1, struct time t2, struct time *difference){
    
    if(t2.secs > t1.secs)
    {
        --t1.mins;
        t1.secs += 60;
    }

    difference->secs = t1.secs - t2.secs;
    if(t2.mins > t1.mins)
    {
        --t1.hrs;
        t1.mins += 60;
    }
    difference->mins = t1.mins-t2.mins;
    difference->hrs = t1.hrs-t2.hrs;
}

Output:
