Binary Tree program - Do NOT use 'struct', you must use classes for each tree class. ( 5 points )

Program 2 Implement a Binary tree using pointers. Store integers. Call your class myBiTree. ( 5 points )

* First, create an item/node/element class. Class would contain ptrLeft, ptrRight, intVar and various functions, etc.

* Next, create the myBiTree class. Class would contains prtHead, node * ptrHead; , and various functions, etc.

// Comment your code well... explaining how each function works

*** Use the following to test....

int main() {

myBiTree T1;

T1.insert(15);

T1.insert(9);

T1.insert(21);

T1.insert(3);

T1.insert(11);

T1.insert(17);

T1.insert(42);

cout << "Preorder: " << T1.preOrderPrintAll();

cout << "Inorder: " << T1.inOrderPrintAll();

cout << "Postorder: " << T1.postOrderPrintAll();

T1.delete(17);

cout << "Preorder: " << T1.preOrderPrintAll();

}
