title: What are the Min and Max variable names length from one million variable names in C++?
body: <p>I have two questions:</p>
  
  <ol>
  <li><p>If we want to declare one million variable names all having the same length then what should be the smallest length possible to use?</p></li>
  <li><p>If we want to declare one million variable names of any possible valid length then what is the maximum size of the variable name required?</p></li>
  </ol>
