title: error: ISO C forbids declaration of `test' with no type
body: <p>I'm learning C++ by myself and I ran into this problem. I wrote several lines of simple code just wanted to test "auto", and it seems that it no longer works. I pasted my code below:</p>
  
  <pre><code>#include &lt;iostream&gt;
  using namespace std;
  int main(int argc, char** argv) {
      auto test=1;
      return 0;
  }
  </code></pre>
  
  <p>Then the error in the title is reported. I use NetBeans IDE. Any advice would be appreciated. </p>
