Question

I’m trying to return a left child as a pointer

I have

 template <typename Type>
 class BSTNode {  
 private:
    int key;                                                             
    Type data;
    BSTNode *left;
    BSTNode *right;
}

And root

template <typename Type>
class BST {          
private:
   BSTNode<Type> *root; 
}

I absolutely need this, I can’t find a way around it (not in the little time I have left)

this->root = auxRoot.getLeftChild();

here is getLeft

template <typename Type>
BSTNode<Type> *BSTNode<Type>::getLeftChild() {
return this->left();
}

Compiling error: left cannot be used as a function. Am I doing somethign wrong ?

Answer 1

left isn’t a function, but a data member, so the parenthesis are illegal. It should be:

this->left;
