Question¶

This program uses the formula C=(5/9)(F-32) to print the Fahrenheit temperatures and their centigrade or Celsius equivalents.

Program

/* Temperature Conversion Program, Fahrenheit to Celsius */

#include<stdio.h>

/* print Fahrenheit-Celsius table for fahr = 0,20 ... 300 */

int main()
{
    int lower,upper,step;
    int celsius,fahr;

    lower = 0;
    upper = 300;
    step = 20;

    fahr = lower;

    while( fahr <= upper)
    {
        celsius =  5 * (fahr - 32) / 9;
        printf("%d\t%d\n",fahr,celsius);
        fahr = fahr + step;
    }

    return 0;
}
