Question

In the following code i am getting compilation error:c2227:left of -> left must point to class/struct/union/generic type. any help how to fix this; I am trying to insert in a binary tree.

typedef struct bnode{
        int key;
        struct bnode* left;
        struct bnode* right;
        }BNODE;

void printKeysReverse(BNODE* current);
void inorder(BNODE* current);
void insert(BNODE **root,int key);
int main(void){
    BNODE* root=NULL;

    insert(&root,27);
    insert(&root,59);
    insert(&root,21);
    insert(&root,38);
    insert(&root,54);
    insert(&root,63);
    insert(&root,8);
    insert(&root,70);
    insert(&root,15);

}
void insert(BNODE **root, int val){
  BNODE *newnode;

  newnode=(BNODE*)malloc(sizeof(BNODE));        
  newnode->right=NULL;
  newnode->left=NULL;

  if ((*root)==NULL){
       *root=newnode;
       (*root)->key=val;              
       return;
       }
  if (val<(*root)->key) insert((&root)->left,val);
  else insert((&root)->right,val);     
}//end 

Answer 1

(&root)->left
&root is NOT a BNODE*
