Different ways of writing the "if" statement
<p>I have seen different ways of writing an <code>if</code> statement.</p>

<p>Which one do you prefer and why?</p>

<h3>Example 1:</h3>

<pre><code>if (val % 2 == 1){output = “Number is odd”;}else{output = “Number is even”;}
</code></pre>

<h3>Example 2:</h3>

<pre><code>if (val % 2 == 1)
{
    output = “Number is odd”;
}
else
{
   output = “Number is even”;
}
</code></pre>

<h3>Example 3:</h3>

<pre><code>if (val % 2 == 1)
output = “Number is odd”;
else
output = “Number is even”;
</code></pre>

<h3>Example 4:</h3>

<pre><code>if (val % 2 == 1){
output = “Number is odd”;
} else {
output = “Number is even”;
}
</code></pre>
