Help me fix my Binary Tree Traversal - Preorder, Inorder, Postorder

Question

I am trying to get the following output
Preorder: 50 5 20 15 27 42 35 25 55 70 60 80 95 90 75
Inorder: 5 15 20 25 27 35 42 50 55 60 70 75 80 90 95
Postorder: 5 20 15 27 42 35 25 55 70 60 80 95 90 75 50

Instead I am getting this
Preorder: 136161285312597531284813109128551336214133138721362114128146401438414645

Answer 1

You had two issues. Your insert wanted int data passed to it and you had characters ('50'). Your order cout statements needed to output space to separate the data. Here is my updated code:
