title: Concerning integer types of bits in Dev-C++
body: <p>I'm using Dev-C++ compiler and wxDev-C++ compiler whilst reading the C++ Primer Plus to learn the programming language. My book's literal explanation of integer types is as follows:</p>
  
  <blockquote>
    <ul>
    <li>A short integer is at least 16 bits wide.</li>
    <li>An int integer is at
    least as big as short.</li>
    <li>A long integer is at least 32 bits wide and
    at least as big as int.</li>
    <li>A long long integer is at least 64 bits wide
    and at least as big as long.</li>
    </ul>
  </blockquote>
  
  <p>Can anyone explain this to me? </p>
