Aday has 86,400 seconds (24*60*60). given a number of seconds in the range of 0 to 1,000,000 seconds, output the time as days, hours, minutes, and seconds for a 24- hour clock. e. g., 70,000 seconds is 0 days, 19 hours, 26 minutes, and 40 seconds. your function should output: time is w days, x hours, y minutes, and z seconds. your function should take the number of seconds as an integer parameter your function must be named howlong.

// here is code in c++.

// include headers

#include <bits/stdc++.h>

using namespace std;

// function that calculate days, hours, minutes and seconds

void howLong(int sec)

{

   // find days

   int days=sec/86400;

   // update the seconds

   sec=sec%86400;

   // find hours

   int h=sec/3600;

   // update the seconds

   sec=sec%3600;

   // find minutes

   int min=sec/60;

   // update the seconds

   sec=sec%60;

   // output

   cout<<sec<<"seconds is "<<days<<" days,"<<h<<" hours,"<<min<<" minutes,and "<<sec<<"seconds."<<endl;

}

// driver function

int main()

{   // variable

   int sec;

   cout<<"Enter seconds:";

   // read the seconds

   cin>>sec;

   // call the function

   howLong(sec);

return 0;

}

Explanation:

Read the seconds from user.Then call the function howLong() with parameter seconds. In the function, it will first find the number of days by dividing the seconds with 86400 then update the remaining seconds.Next it will find the hours by dividing the remaining seconds with 3600 and update the remaining seconds.After that it will find the minutes by dividing the remaining seconds with 60 and update the remaining second.Then it will print the days, hours, minutes and seconds.

Output:

Enter seconds:70000

40seconds is 0 days,19 hours,26 minutes,and 40seconds.

the answer is d underlined.
