/*
Modify the temperature conversion program to print a heading above the table.
*/

#include <stdio.h>

/* print fahrenheit-Celsius table for fahr = 0, 20, ..., 300; floating-point
version */
main()
{
    float fahr, celsius;
    int lower, upper, step;

    lower = 0;   /* lower limit of temperature table */
    upper = 300; /* upper limit                      */
    step  = 20;  /* step size                        */

    printf("Fahr Celsius\n");
    fahr = lower;
    while (fahr <= upper)
    {
    	celsius = (5.0 / 9.0) * (fahr - 32.0);
    	printf("%3.0f %6.1f\n", fahr, celsius);
    	fahr += step;
    }
}

/* Output:

Fahr Celsius
  0  -17.8
 20   -6.7
 40    4.4
 60   15.6
 80   26.7
100   37.8
