title: C code autocomplete in Eclipse
body: <p>I'm a Java developer and I've downloaded the Eclipse for C (course purposes) and to my amazement the control+space shortcut (for autocomplete) did not work.
  I've created a new project and a new class using the wizzards and started to type "print" and then tried to find an autocomplete feature.
  After a bit of googling I arrived at <code>C/C++</code>-><code>Editor</code>-><code>Content Assist</code>-><code>Advanced</code> and there  I verified that <code>Help proposals</code>,<code>Parsing-based proposals</code> and <code>Template proposals</code> options were checked.
  I then went over to the <code>Keys</code> preferences page using the link at that page and entered a binding for all relevant content assist from before <code>C\C++ Content Assist (type...)</code> and chose in the <code>When</code> box the <code>C\C++ Editor</code> option.
  But alas no autocompletion was offered.
  Can someone please point me to the right direction?</p>
  
  <p><strong>UPDATE:</strong> I'm accepting the answer not because I'm sure it's right but because I've realised I've made some mistakes with the configuration of the eclipse and have seen that with another installation/configuration (i.e. a friend of mines) eclipse does auto complete, even if it still lack many of the java version features.</p>
