Convert seconds to Days, Minutes and Seconds

Question

Hey everyone. I've continuing to learn C++ and 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.

Thanks, Dan.

Answer 1

I think is the challenge from Stephen Prata's book. I did it as follows:

#include <iostream>

using namespace std;

int main()
{
    long input_seconds = 31600000;

    const int cseconds_in_day = 86400;
    const int cseconds_in_hour = 3600;
    const int cseconds_in_minute = 60;
    const int cseconds = 1;

    long long days = input_seconds / cseconds_in_day;
    long hours = (input_seconds % cseconds_in_day) / cseconds_in_hour;
    long minutes = ((input_seconds % cseconds_in_day) % cseconds_in_hour) / cseconds_in_minute;
    long seconds = (((input_seconds % cseconds_in_day) % cseconds_in_hour) % cseconds_in_minute) / cseconds;
    cout << input_seconds << " seconds is " << days << " days, " << hours << " hours, " << minutes << " minutes, and " << seconds << " seconds.";

    cin.get();
    return 0;
}
