title: Counting down with a For Loop
body: <p>I'm currently learning C via K&amp;R's "The C Programming Language". Theres an exercise (1-5) that wants me to convert Fahrenheit to Centigrade using a for loop but with the values for Fahrenheit to be displayed in a descending order from my specified maximum value for it. The previous exercise was the same idea but in ascending order (which I completed successfully). I tried to complete the descending order task and I get no output what so ever in the console. </p>
  
  <p>I'm not sure why this isn't working (I hope its not so obvious its embarrassing!)</p>
  
  <pre><code>#include &lt;stdio.h&gt;
  
  int main() 
  {
      int fahrenheit;
  
      for(fahrenheit = 250; fahrenheit &lt;= 0; fahrenheit -= 25)
      {
          printf("%3d degrees fahrenheit is %3.3f degrees celcius\n", fahrenheit, (5.0 / 9.0) * (fahrenheit - 32));
      }
  
      return 0;
  }
  </code></pre>
