title: variable declared and not used in Go
body: <p>In the following code:</p>
  
  <pre><code>func PrimeF(n uint64) {
  var i,t uint64 = 2,3
  
  
  for ; i &lt; n; {
      if n%i == 0 {
          n /= i
      }
  
     }
  }
  </code></pre>
  
  <p>Why do I get the error message: "t declared and not used"?</p>
