Question

Write a program in C that prompts the user for a number of seconds and then converts it to h:m:s format. Example: 5000 seconds should display as 1:23:20 (1 hour, 23 minutes, 20 seconds.) Test with several values between about 100 seconds and 10,000 seconds.

use unint and remainders for this and keep it as simple as possible.

Answer 1

#include <stdio.h>

int main()
{
   //Declaring variables
int hrs,mins,secs,remainder;
int seconds;
char ch;
  
  
/* This while continues to execute until
   * the user enters other than 'Y' or 'y'
   */
while(1)
{
   //Getting the number of seconds by the user
printf("Enter the no of seconds :");
scanf("%d",&seconds);
  
//calculating the no of hours
hrs=seconds/3600;
  
remainder=seconds%3600;

//calculating the no of minutes
mins=remainder/60;
  
remainder=remainder%60;
  
  
//calculating the no of seconds
secs=remainder;
  
  
//Dispalying the output
printf("Hrs:Mins:Secs = %d:%d:%d",hrs,mins,secs);
  
   //Prompting the user user to continue the program again
   printf("\nDo you Want to continue(Y/N):");
       scanf(" %c",&ch);

       if(ch=='y'||ch=='Y')
       {
       continue;
       }else
       {
       printf("** Program Exit **");  
       break;
       }  
   }
  
return 0;
}
