why no output is displaying
<p>Why this code is not displaying any output: Instead if we use </p>

<pre><code>cout &lt;&lt; &amp;s1.f 
</code></pre>

<p>or </p>

<pre><code>cout &lt;&lt; &amp;s1.i
</code></pre>

<p>gives the proper output. </p>

<pre><code># include &lt;iostream&gt;
using namespace std;

struct s
{
char c;
int i;
float f;

}s1;

int main()
{
cout &lt;&lt; &amp;s1.c;
}
</code></pre>
