So what is the problem?

CodePudding user response:

I think: the second sequence traversal is supposed to be like this:
The Status InOderTraverse (BiTree T, Status (* Visit) (ElemType e)) {
If (T) {
If (InOderTraverse (T - & gt; Lchild, Visit)
If (Visit (T - & gt; Data))
If (Visit (T - & gt; Data) if (InOderTraverse (T - & gt; Rchild, Visit)
Return ok;
Return the error;
} the else return ok;
}

Header file indicates a fault, malloc, there??????????????

You should be C language, a header file to add. H

Added. H article wrong number again for a few more, I think it should be me where there is wrong,
Have to look at
