<p>What's the difference between using dot notation and the pointer way? </p>

<p>Instantiating an object with or without a pointer.</p>

<p>Instantiate w/o a pointer = then use dot notation </p>

<p>Instantiate w/ a pointer = then use -> </p>

<p>What are the differences between both? When and why should one be used over the other? </p>
