Write a program in C++ to create a Binary Search tree (BST) of integers. The program will perfor these operations: Insert node(s), Traverse In-order, Search node, Delete node, Leaf Count, Pare of a node and Quit. Use the header file similar to this: #include #ifndef BT H #define BT H using namespace std; class BT { private: struct node { int data; node* left; node* right; }; node* root; public: BT (); bool isEmpty() const { return root == NULL; } void insert(int); void print_inorder(); void inorderTrav(node*); void searchBST (int); void deleteNode(int); int count(); int leafCount(node*); void nodeParent(int); //Constructor //Check for empty //Insert item in BST //In-order traversing driver //In-order traversing //Searches BST for a specific nod //Delete item from BST //Count driver //Counts number of leaves in BST //Finds parent of a node }; #endif Use the following menu in your program. MENU 1. Insert node(s) 2. Traverse In-order 3. Search node 4. Delete node 5. Leaf Coun 6. Parent of a node 7. Quit Enter your choice:

Use the following characters in the given order to form the BST tree:
20 10 15 30 25 40 0 5 35
(Hints: 1. Before you start working on the program, you draw the BST for the given order of the above
characters. It will help you check your output for the options in the menu. 2. While working on the program,
use enter few items for testing - such as 20 10 15 30, 3. You work on one menu at a time then it is easier to
test and manage the program instead of writing the whole program for entire menu then test your
program.)
Option 4:
Deletes a node from the BST.
It will prompt: Enter item you want to delete: 30
Option 1:
Inserts node(s) in a BST.
Enter Your Choice <1 - 7> 1
Enter number of items to insert: 4
If the item is found then delete the item from the BST and displays the message -

Enter node: 30
Inserted.
Option 6:
Enter the item and it will display the Parent of that item.
It will prompt: Enter the item you want to find the Parent of:
Traverse the tree in in-order and display the node info and its left child info and
right child info. If a node does not have a child then display NIL.
Option 2:
Enter Your Choice <1 -7> 2
The parent of is_
If the item has no parent then it displays:
Sample output:
has no parent.
Traversing In-order
Node Info Left Child Info Right Child Info
Ex:
Enter the item:
10

10
NIL
15
The parent of 10 is 20.
15
NIL

Option 7:
Quit the program.
Option 3:
Search for the item in the BST.
It will prompt: Enter item you want to search for:
10
If the item is found, then display the message - "
is found in the BST". If the
item is not found then it will display -"
is not found in the BST"
10 is found in the BST.

Write a program in C++ to create a Binary Search tree (BST) of integers. The program will perform
these operations: Insert node(s), Traverse In-order, Search node, Delete node, Leaf Count, Parent
of a node and Quit.
Use the header file similar to this:
#include <iostream>
#ifndef BT_H
#define BT_H
using namespace std;
class BT
{
private:
struct node
{
int data;
node* left;
node* right;
};
node* root;
public:
BT();
bool isEmpty() const { return root == NULL; }
void insert(int);
void print_inorder();
void inorderTrav(node*);
void searchBST (int);
void deleteNode(int);
int count ();
int leafCount(node*);
void nodeParent(int);
//Constructor
//Check for empty
//Insert item in BST
//In-order traversing driver
//In-order traversing
//Searches BST for a specific node
//Delete item from BST
//Count driver
//Counts number of leaves in BST
//Finds parent of a node
};
#endif
Use the following menu in your program.
MENU
1.
Insert node(s)
2.
Traverse In-order
3.
Search node
4.
Delete node
5.
Leaf Count
6.
Parent of a node
7.
