title: How to show warnings in VSCode editor for a .cpp file?
body: <p>Is it possible to tweak VSC somehow to see GCC warnings in the text editor?<br>
  Refer to the screenshot below - it shows only errors in the editor.</p>
  
  <p>I'm using 1.43.2 version with C/C++ extension 0.26.3 installed.<br>
  Tried adding <code>-Wall</code> compiler flag to "args" in <code>tasks.json</code> but it didn't help.</p>

  <p>Below are my settings:  </p>
  
  <pre><code>{
      "editor.fontSize": 13,
      "files.autoSave": "afterDelay",
      "files.autoSaveDelay": 100,
      "files.insertFinalNewline": true,
  }
  </code></pre>
