title: How to assign to a variable an alias
body: <p>I want to call the same variable with a different name, how can I assign it an alias?</p>
  
  <p>Do I stick to using a macro, like</p>
  
  <pre><code>#DEFINE Variable Alias
  </code></pre>
  
  <h1>In summary:</h1>
  
  <ol>
  <li>I prefer to apply it in C</li>
  <li>I have a signal which can be more than one type of variable (temperature, distance, etc..)</li>
  <li>I want to assign more than one alias to that signal</li>
  </ol>
  
  <hr>
  
  <p>I'm currently doing it in C using functions as the method for renaming.</p>
  
  <p>So given the variable: <code>int signal</code></p>
  
  <p>I'd do the following</p>
  
  <pre><code>int Temperature(){return signal;}
  </code></pre>
