title: C++ function argument, int short
body: <p>When I only use short integers in my program, is it better to use:</p>
  
  <pre><code>void printVars(int x1, int x2, int x3)
  </code></pre>
  
  <p>or </p>
  
  <pre><code>void printVars(short int x1, short int x2, short int x3)
  </code></pre>
  
  <p>as argument for my functions?</p>
  
  <p>Thank you in advance.</p>
