Usage & versus &&
<p>I came across this doubt and hope some one here would be able to help me out on this</p>

<pre><code>bool Isvalid = isValid &amp; CheckSomething()

bool Isvalid = isValid &amp;&amp; CheckSomething()
</code></pre>

<p>second case could be scenario for short circuiting</p>

<p>So can't we always use just <code>&amp;</code> instead &amp;&amp;.</p>
