title: Does sequential 'new' operators make contiguous allocated memory?
body: <p>I heard std::vector is good because it guarantee contiguous allocated memory (cache-friendly). Then how about sequential 'new' operator like this?</p>
  
  <pre><code>{
      new Test1();
      new Test2();
      new Test3();
  }
  </code></pre>
  
  <p>Does not it make contiguous allocated memory on heap?</p>
