In this program you will read in the number of seconds and convert it to days, hours, minutes and remaining seconds. your program will make use of long long int variables for all calculations. note: the use of long long int requires that you have c++11 support. you should have this automatically if you are using a newer version of visual studio. the support is there for gcc as well, but you may need the -std=c++11 or -std=c++0x compiler flag.

// here is code in c++.

// include headers

#include <bits/stdc++.h>

using namespace std;

// main function

int main()

{

// variables

long long int inp_sec,days,hours,minutes,sec;

long long int s;

cout<<"please enter the seconds:";

 // read the input seconds

cin>>inp_sec;

 // make copy of input second

s=inp_sec;

 // compute days,86400 seconds in a day

days=inp_sec/86400;

 // update the seconds after counting days

inp_sec=inp_sec%86400;

 // compute hours, 3600 seconds in an hour

hours=inp_sec/3600;

 // update the seconds after counting hours

inp_sec=inp_sec%3600;

 //compute minutes, 60 seconds in a minute

minutes=inp_sec/60;

 // compute remaining seconds

sec=inp_sec%60;

 // print the output

cout<<s<<" seconds is equal to "<<days<<" days "<<hours<<" hours "<<minutes<<" minutes "<<sec<<" seconds "<<endl;

return 0;

}

Explanation:

Declare variables "inp_sec","days","hours","minutes" and "sec" of long long int type. read the seconds from user and assign it to variable "inp_sec".Make a copy of input  seconds.Then compute the days by dividing inp_sec with 86400 and update the inp_sec. then find hours by dividing inp_sec with 3600 and update the inp_sec.Similarly  find the minutes and remaining seconds.After this print the output.

Output:

please enter the seconds:83647362                                                                                                                            

83647362 seconds is equal to 968 days 3 hours 22 minutes 42 seconds
