title: Expected "," or "..." before numeric constant
body: <p>I´ve tried looking up an answer but I was unable to deduct from any of those what exactly the issue here is. When I try to verify it says &quot;Expected &quot;,&quot; or &quot;...&quot; before numeric constant&quot; and highlights &quot;#define Odvesna&quot;</p>
  <pre class="lang-cpp prettyprint-override"><code>#define A1              35
