title: Can I declare a function without specifying a type for one of the parameters?
body: <p>Can a function be defined like this:</p>
  
  <pre><code>int foo(int temp1, int temp2 temp3) {
     ...
  }
  </code></pre>
  
  <p>Specifically with <code>temp2</code> and <code>temp3</code>, will that cause errors? If not, what's the overall effect?</p>
