2. #include<conio.h>
4. using namespace std;
6. int main()
7. {
8. int hours,mins,seconds;
9. bool status = true;
11. cout << "Enter Hours (00-23): "; cin >> hours;
12. cout << "Enter Minutes (00-59): "; cin >> mins;
13. cout << "Enter Seconds (00-59): "; cin >> seconds;
15. if((hours >= 24 || hours < 0))
