The different with methods
<p>I am new to C# and I am trying to understand what is the difference when you are passing and argument or no argument in a method.</p>

<p>I think I kind of understand. Would it be if you was to pass an argument it would be something like this.</p>

<pre><code>int numA = 4;

int productA =  squar(numA); 
</code></pre>

<p>I just don't understand how to have a method where it is not passing an argument. </p>
