title: Why use pointers?
body: <p>I know this is a really basic question, but I've just started with some basic C++ programming after coding a few projects with high-level languages. </p>
  
  <p>Basically I have three questions:</p>
  
  <ol>
  <li>Why use pointers over normal variables?</li>
  <li>When and where should I use pointers?</li>
  <li>How do you use pointers with arrays?</li>
  </ol>
