從二叉樹中刪除節點

Question

請幫忙。我的下面的刪除功能有什麼問題。似乎無法解決它

我似乎得到一個錯誤： 類聲明似乎很好。主要的問題是有這個remove函數工作

void binaryTree::Remove(int) { 
    if (node != NULL) 
    { 
    Node* tmptr = node; 
    int rootdata = node->data; 
    /int rSubtree; 
    } 
    { 
    // Case 0- no child 
    if (node->lChild == NULL && node->rChild == NULL) 
    { 
     node = NULL; 
     //parent-   //set the parent of the node to NULL 
     delete node; 
    } 
    // has one child 
    else if (node->lChild == NULL && node->rChild != NULL) 
    { 
     node = node->rChild; 
     node->rChild = NULL; 
     delete node; 
    } 

    else if (node->lChild != NULL && node->rChild == NULL) 
    { 
     node = node->lChild;`enter code here` 
     node->lChild = NULL; 
     delete node; 
    } 
}

嘗試更換node = NULL與delete node;否則你想刪除NULL。
