How to get all child nodes of a specific node in non-binary tree in C++
<p>I'm being stuck because I don't know how to get all child nodes of a specific node in non-binary tree.</p>

<p>For example, the root node is A. </p>

<p>A = {B, C}</p>

<p>B = {D, E, F}</p>

<p>E = {G}</p>

<p>I want to get all child nodes of B = {D, E, F, G}</p>

<p>How can I do? Thank you very much.</p>
