Traverse Left Subtree with Post Order and Right Sub tree with PreOrder ~ C++ Codes Tree

Traverse root left sub tree with post order ☻
and then print root ☻
and then root right sub tree with pre order ☻

#include<iostream.h>
#include<conio.h>
class Node{
private:
int data;

public:

right=left=NULL;
}Node *root;

newnode->data = data;
if (root == NULL){
root=newnode;
return;
}

p=q=root;
while (q!=NULL){
p=q;
if (newnode->data> q->data)
q = q->right;
else q = q->left;
}
if (newnode->data> p->data)
p->right = newnode;
else p->left = newnode;
}




void mixorder(Node *root){
cout<<"\n\nPost Order: ";
postorder(root->left);
cout <<"\n\nRoot: "<<root->data <<"  ";
cout<<"\n\nPre Order: ";

}
}
