title: C - warning: unused variable
body: <p>I have the following code below in a function.</p>
  
  <pre><code>char * stringFiveds = strtok(stringFive[3], "ds");
  </code></pre>
  
  <p>When I compile i get the warning unused variable.</p>
  
  <p>I don't plan on using <code>srtingFiveds</code> in this function. I want to use it in <code>main()</code>. I have two parts to this question.</p>
  
  <ol>
  <li>How to solve this warning if I don't want to use the <code>stringFiveds</code> in this function.</li>
  <li>How do I make it accessible in other functions so i can use it in other function i will create. </li>
  </ol>
  
  <p>I'm new to this, can you please be as detailed as possible.</p>
