[Dev-C++] calculating Celsius to Fahrenheit

[Mitchell, T. (HNA) <Tam...@hj...>]

I am attempting to write a program the convert integer Fahrenheit
temperature from 0 to 212 degrees to floating point Celsius temperature with
3 digits of precision.

The output should be in two right-justified columns of 10 characters each
and the Celsius temp should be preceded by a sign for positive and negative.

Any suggestions.

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

float calc(float);


int main()
{
         float c, f;
         int fahr;
	 
	     printf("Enter Fahrenheit temperature: \n");
	     scanf("%d", &fahr);

	 for (f=0; f<=212; f++)
	   {
	     c = calc(fahr);
	     printf("%2f", 10,3, c, -c);
	   }
	 


      system("PAUSE");
      return 0;
}

float calc(float fahr)
{
  float cels = 5.0 / 9.0 * (fahr - 32);
  return cels;
  
}
