Not able to print R tree in a output file - c++

Question

Not able to print r tree using print function given an input.txt.
Unable to get any output.
input is-
add 2 3 1 2 1
add 7 10 1 2 2
add 1 2 5 8 3
print
ifstream
inputFile("C:/Users/YOLO/Documents/NetBeansProjects/rtree_header/input.txt");
ofstream outFile; outFile.open("C:/Users/YOLO/Documents/NetBeansProjects/rtree_header/output.txt");
if (operation == "print") {
myRtree.PrintRtree(outFile);
continue;
}
// I want to print tree structure in an output file
void Rtree::PrintRtree(ofstream &outputStream) {
if (outputStream.is_open() == true) {
if (root->childs == NULL) {
outputStream << "tree is empty" << endl;
return;
}
_PrintRtree(root, 0, outputStream);
outputStream << endl;
}
else
cout << "output stream error" << endl;
}
// I want to print tree structure containg root,node and leaves
void Rtree::_PrintRtree(Node* curNode, int level, ofstream &outputStream) {
for (int i = 0; i < level; i++) {
outputStream << "\t";
}
switch (curNode->type) {
case NODE:
outputStream << "NODE";
break;
case LEAF:
outputStream << "LEAF";
break;
case OBJECT:
outputStream << "OBJECT";
break;
}
outputStream << " x1=" << curNode->covering.x1
<< " x2=" << curNode->covering.x2
<< " y1=" << curNode->covering.y1
<< " y2=" << curNode->covering.y2;
if (curNode->type == OBJECT)
outputStream << " data=" << curNode->data << endl;
else {
outputStream << endl;
for (int i = 0; i < curNode->objCount; i++) {
_PrintRtree(curNode->childs[i], level + 1, outputStream);
}
}
