title: Preprocessor expected - MS Visual / C++
body: <p>I'm just trying to use MS Visual for some really simple C++ coding for school purposes. The point is I can't even write a simple hello-world alike program.
  I've got that error "Preprocessor expected" in line with library. Line with code looks like this: <code>#include &lt;iostream&gt;</code></p>
  
  <p>Any help with solving this (probably) minor problem is welcomed.</p>
  
  <p>Here is whole code:</p>
  
  <pre><code>#include &lt;iostream&gt;
  
  int main()
  {
      std::cout &lt;&lt; "aogaohgo";
  }
  </code></pre>
