I am supposed to make a binary hash tree mix of code. I know what I am doing for the most part, but its been a while since I have done some serious C++ coding. The compiler is yelling at me because it doesn't like my last definition in my public section of the class.

Am i getting errors about "node" because its in the private section? Thanks

Errors:

binaryhash.h line 46 You need a forward declaration of the struct node . Or just move the private part before the public one. binaryhash.h line 46 void deleteNode(node *n) takes a pointer, not a value. binaryhash.h line 54 This one I don't really get, probably some spelling mistake or something.

Thank you, switching the private and public section around fixed all of the errors. Makes sense. Marked as solved.

Glad to see someone polite ;P
