/*
Modify the temperature conversion program to print the table in reverse order, 
that is, from 300 degrees to 0.
*/

#include <stdio.h>

/* print Fahrenheit-Celsius table in reverse order */
main()
{
    int fahr;
    
    for(fahr = 300; fahr >= 0; fahr -= 20)
    {
    	printf("%3d %6.1f\n", fahr, (5.0 / 9.0) * (fahr - 32));
    }
}

/* Output:

300  148.9
