compounding / while loops

Question

#include <stdio.h>

int main(void)
{
  int days, hours, mins;
  float a, b, c, total, temp, tempA, tempB;

  a = 3.56;
  b = 12.50;
  c = 9.23;
  total = a+b+c;
  days = total / 24;

  temp = total/24 - days;

  hours = temp * 24;

  tempA = temp*24 - hours;

  mins = tempA*60;

  while (hours >= 24)
    {
      hours= hours-24;
      days +=1;
    }
  while  ( mins >= 60)
    {
      mins=mins-60;
      hours +=1;
    }
  printf("days:%d\n", days);
  printf("hours:%d\n", hours);
  printf("mins:%d\n", mins);


  return 0;
}

I wanted to convert decimal hours to real time and I can do it fine but I wanted to increase days hours if the hours is beyond 24 and if mins is beyond 60mins. the while loop does subtract and it does print out the new value but the hours / days aren't getting compounded. It was 1 day 1 hour 77mins I wanted it to read 1 day 2 hours 17mins but I'm getting 1 day 1 hour 17 mins.

Answer 1

Running your program I'm getting:

days:1
hours:1
mins:17

and that's what I expect considering that total should be 25.29.
