What does the output which I get from printf("%d") mean? : <p>I tried a code today and noticed that printf("%d") still have an output.
On my computer I get a output of "1487504216".
I would like to know why I gets a output and what the output means.
The following is the code I have tried.</p>

<pre><code>#include &lt;stdio.h&gt;

int main()
{
    printf("%d");

    return 0;
}
</code></pre>
