classes(recursion in methods)

[sharangchopra]

i was writing a code for binary tree class.I am not able to write the code for in order print.
my code https://ideone.com/7a0u3a

the problem is that the method in_order_print() has no argument,So how do i call it recursively.

You could implement it without recursion, or create another function that uses recursion that you call from in_order_print().

how can i do it without recursion ?
thanks

This problem is easier solved using recursion. You are right that calling tree::in_order_print() recursively will not work. What you could do is to create another function that takes a node object as argument (or the function could be a member of the node class). This function could be recursive and the tree::in_order_print() function could call this function once, passing the root as argument.

thanks
it is working fine.
