Contoh: Program ke Perbedaan Waktu
// Computes time difference of two time period
// Time periods are entered by the user
#include
using namespace std;
struct TIME
{
int seconds;
int minutes;
int hours;
};
void computeTimeDifference(struct TIME, struct TIME, struct TIME *);
int main()
{
struct TIME t1, t2, difference;
cout << "Enter start time." << endl;
cout << "Enter hours, minutes and seconds respectively: ";
cin >> t1.hours >> t1.minutes >> t1.seconds;
cout << "Enter stop time." << endl;
cout << "Enter hours, minutes and seconds respectively: ";
cin >> t2.hours >> t2.minutes >> t2.seconds;
computeTimeDifference(t1, t2, &difference);
cout << endl << "TIME DIFFERENCE: " << t1.hours << ":" << t1.minutes << ":" << t1.seconds;
cout << " - " << t2.hours << ":" << t2.minutes << ":" << t2.seconds;
cout << " = " << difference.hours << ":" << difference.minutes << ":" << difference.seconds;
return 0;
}
void computeTimeDifference(struct TIME t1, struct TIME t2, struct TIME *difference){
if(t2.seconds > t1.seconds)
{
--t1.minutes;
t1.seconds += 60;
}
difference->seconds = t1.seconds - t2.seconds;
if(t2.minutes > t1.minutes)
{
--t1.hours;
t1.minutes += 60;
}
difference->minutes = t1.minutes-t2.minutes;
difference->hours = t1.hours-t2.hours;
}
Keluaran
Enter hours, minutes and seconds respectively: 11 33 52 Enter stop time. Enter hours, minutes and seconds respectively: 8 12 15 TIME DIFFERENCE: 11:33:52 - 8:12:15 = 3:21:37
Dalam program ini, pengguna diminta untuk memasukkan dua periode waktu dan dua periode ini disimpan dalam variabel struktur t1 dan t2 masing-masing.
Lalu, itu computeTimeDifference()
fungsi menghitung perbedaan antara periode waktu dan hasilnya ditampilkan pada layar dari main()
berfungsi tanpa mengembalikannya (panggilan dengan referensi).
