We can't help you unless you can give us some more information. What exactly are the errors you are getting, and can we see your code? (Please make sure you wrap them in [code] tags - if you don't know what these are, please refer to this section in our FAQ).

It seems that, for some reason, our forums aren't letting your code appear. I'll contact the site administrators and let them know about the problem.

If this is C++, then you don't need the struct keyword in from of the left and right members of bst. Also, you declare this struct as bst, but I see some references in your code to a nonexistant struct/class called node. Maybe you should rename your struct BinaryNode or something appropriate.

i changed bst as node.
but what is "declaration terminated incorrectly" it is the error.is there any error un main function?it is showing in main function.what is meaning of that error.
