Node* current = getChild(); // get the child node Node* parent = current->getParent(); // get the parent of the child node int numChildren = parent->getChildCount(); // get the number of children of the parent node
Node* root = getRoot(); // get the root node of the tree Node* current = getNode(); // get some node in the tree while (current != root) { Node* parent = current->getParent(); // get the parent of the current node // do some operations on the parent node current = parent; // move up the hierarchy to the parent node }In this example, we first get the root node of the tree using some other function. Then, we start from some node in the tree and keep moving up the hierarchy until we reach the root node. At each step, we get the parent node of the current node and perform some operations on it.
