title: Visual Studio Code-Cannot open source file "iostream"
body: <p>
  I just want to try c++ coding with Visual Studio code. I have installed vscode 1.18.1 to my laptop (Win10-64).</p>
  
  <p>
  I got errors by typing following code:</p>
  
  <pre><code>#include &lt;iostream&gt;
  using namespace std;
  int main()
  {
      std::cout &lt;&lt; "Hello world!" &lt;&lt;endl;
      return 0;
  }
  </code></pre>
  
  <p>
  Should happen no Error. C:\Users\Harri\OneDrive\Tiedostot\Demo2.vscode\c_cpp_properties.json -content:</p>
  
  <p>"path": [
                      "/usr/include",
                      "/usr/local/include",
                      "${workspaceRoot}"
                  ],
