title: Integer with range from 0 to 255
body: <p>I want to declare a structure with 4 integer and each of them can only be from 0 to 255. Is there a way for it? Currently, I'm doing it by checking the input(in the input function).</p>
  
  <pre><code>struct
  { 
      int num1;
      int num2;
      int num3;
      int num4;
  } ip;
  </code></pre>
