How does vector's growth function work? : <pre><code>int main () {
    std::vector &lt;int&gt; elements;
    elements.push_back (1);
    elements [10000] = 102;
    std:: cout &lt;&lt; elements [10000];
    return 0;
}
</code></pre>

<p>How does the above code work? As far as I have read, vector's growth will be 1.5 - 2x. So how is the 10000th element stored here? Isn't the expected behavior here a "Segmentation fault"? But the above runs successfully.</p>
