title: emacs completions or IntelliSense the same as on Visual Studio
body: <p>emacs 22.2.1 on Linux</p>
  
  <p>I am doing some C/C++ programming using emacs. I am wondering does emacs support completions (IntelliSense in Visual Studio).</p>
  
  <p>For example when filling structures I would like to see the list of members when I type the dot operator or arrow operator.</p>
  
  <p>The same would go for function signatures that give me the types I am passing would display.</p>
