title: Base class of everything in c++
body: <p>In Java, the <code>Object</code> class is the base class of all classes. Is there any such class in C++ as well?</p>
  
  <p>My motivation for the question is:</p>
  
  <pre><code>try
  {
      if (something) throw int(a);
      if (something) throw char(b);
      if (something) throw float(c);
  }
  catch(...)
  {
      handle
  }
  </code></pre>
  
  <p>Is there any other way to handle all these exceptions using single catch block apart from this?</p>
