double to float

I wrote a program converting fahrenheit to celsius but the requirement calls for using int for fahrenheit and float for celsius. Obviously thats leading to possible loss of data warnings. What can I do? And does anyone know why the "0" isn't showng in the celsius column? I think it was there but I changes something and now its gone? :confused:

Code:

---

#include <stdio.h>
#include <stdlib.h>


int main()

{

int fahrenheit;
float celsius;
int lower, upper, step;

printf( "Fahrenheit    Celsius\n\n" );

lower = 0;
upper = 212;
step = 1;

fahrenheit = lower;



while (fahrenheit <= upper)
        {
                celsius = ( 5.0/9.0 ) * ( fahrenheit - 32.0 );
                printf( "%10.0d  %+10.3f\n", fahrenheit, celsius );
                fahrenheit = fahrenheit + step;
        }
        return 0;
}

Do these changes

Code:

---

#include <stdlib.h>


int main()

{

int fahrenheit;
float celsius;
int lower, upper, step;

printf( "Fahrenheit    Celsius\n\n" );

lower = 0;
upper = 212;
step = 1;

fahrenheit = lower;



while (fahrenheit <= upper)
        {
                celsius = ( 5.0f/9.0f ) * ( fahrenheit - 32.0f );
                printf( "%10.0d  %+10.3f\n", fahrenheit, celsius );
                fahrenheit = fahrenheit + step;
        }
        return 0;
}

Code:

---

#include <stdio.h>
#include <stdlib.h>

int main() {

  int fahrenheit;
  float celsius;
  int lower, upper, step;

  printf( "Fahrenheit    Celsius\n\n" );

  lower = 0;
  upper = 212;
  step = 1;

  fahrenheit = lower;

  while (fahrenheit <= upper)
      {
        celsius = ( 5.0f/9.0f ) * ( fahrenheit - 32.0f );
        printf( "%10.0d  %+10.3f\n", fahrenheit, celsius );
        fahrenheit = fahrenheit + step;
      }
  return 0;
}
