Hi, can someone please help me review my code

I just have a few errors

I listed the requirements

Please provide functions for possible errors

Below is a copy of my code

int input;

binaryTree tree;

//create do-while loop to at least run the code once

do

menu();

cin >> choice;

cout

switch (choice)

{

case 1:

cout

tree.insertNode(input);

cout

break;

case 2:

Functional Requirements: A looping, menu-driven program that allows the user to create a binary tree and to display data about the tree Pro gramming Requirements Using the IntBinary Tree class from Chapter 21 as the starting point, add the following member functions Leaf Counter (which counts and returns the number of leaf nodes in the tree) Tree Height (which counts and returns the height of the tree - the height is the number of levels it contains Tree Width (which counts and returns the width of the tree the width is the largest number of nodes in the same level.) Write a menu-driven program that will allow the user to 1. Insert numbers 2. Display the tree (in order) 3. Display Leaf Count 4. Display Tree Height 5. Display Tree Width 6. Exit Your program shouldcontain high-level validation for numeric input (use a while loop and allow use to re-enter the data) Testyour program as follows Insert the following numbers (one at a time through menu option 1): 10, 87, 9, 55, 13, 40, 22,1,0,77, 0, 4, 55 33, 22 Display the tree Display the leaf count Display the tree height Display the tree width
