title: C function (without parameters) call with parameters
body: <p>I'm wondering something like this is possible:</p>
  
  <pre><code>// declaration
  void func();
  
  int main()
  {
      int ar[] = { 1, 2, 3 };
      func(ar); // call with parameter
      return 1;
  }
  
  void func() // no parameters
  {
      // do something
  }
  </code></pre>
  
  <p>Can someone explain me this and especially how can I access <code>ar</code> in <code>func()</code>?</p>
