Hello. I'm getting one error in my program which is "No matching function call to 'printbinarytree'

Question

I created a binary tree. The code prints out inorder, postorder and preorder traversal. In my main program I am getting an error message

No matching function call to 'printbinarytree'.

Here is my code:

$("#frm1").submit(function (e) {

Can someone help me to find the problem?
