what will be the result of atoi (argv[1])?
<p>I just want to know that what will these line actually do.</p>

<pre><code>    int main(int argc, char *argv[])
</code></pre>

<p>And especially this one.</p>

<pre><code>    int n = atoi (argv[1]);
</code></pre>

<p>I read this from a book but i cannot understand these line.</p>
