Convert seconds to Days, Minutes and Seconds


I've been set the 'challenge' of converting seconds to format as the Days,Minutes and Seconds.

For example: 31600000 = 365 days, 46 minutes, 40 seconds.

using namespace std;
const int hours_in_day = 24;
const int mins_in_hour = 60;
const int secs_to_min = 60;

long input_seconds;
cin >> input_seconds;

long seconds = input_seconds % secs_to_min;
long minutes = input_seconds / secs_to_min % mins_in_hour;
long days = input_seconds / secs_to_min / mins_in_hour / hours_in_day;

cout << input_seconds << " seconds = "
     << days << " days, "
     << minutes << " minutes, "
     << seconds << " seconds ";

return 0;

It works and comes up with the correct answer but after completing it I looked at how other people had tackled it and theirs was different. I'm wondering If I'm missing something.


Solution

  • One of the things about programming is that there is never just one way to do something. In fact if I were to set my mind to it, I might be able to come up with a dozen completely different ways to accomplish this. You're not missing anything if your code meets requirements.

    For your amusement, here's a way to format up hours:minutes:seconds under Windows (elapsed is a double & represents number of seconds elapsed since... something)

    sprintf_s<bufSize>(buf, "%01.0f:%02.0f:%02.2f", floor(elapsed/3600.0), floor(fmod(elapsed,3600.0)/60.0), fmod(elapsed,60.0));
