C++ Eclipse：二进制搜索树节点->数据=变量似乎不起作用

生成成功，但运行时在停止

节点->数据=投标

在下面的函数中。因此，输出成功打印出来，直到加载CSV文件888 cout语句为止。我不确定是什么阻止它运行该代码

void BinarySearchTree::Insert(Bid bid) {
    // FIXME (2a) Implement inserting a bid into the tree
cout << "Loading CSV file 333" << endl;
Node* node = root;
cout << "Loading CSV file 888" << endl;
node->data = bid;
cout << "Loading CSV file 777" << endl;
if (root == NULL){
    //root->data = bid;
//root->left = 0;
//root->right = 0;
root = node;
node->left = NULL;
node->right = NULL;
cout << "Loading CSV file 444" << endl;
}
else
{
cout << "Loading CSV file 666" << endl;
Node* cur;
    cur = root;
    while (cur != NULL){
      if (strToDouble2(node->data.bidId) < strToDouble2(cur->data.bidId)){
         if (cur->left == NULL){
           cur->left = node;
           cur = NULL;
         }
         else{
           cur = cur->left;
         }
      }
      else
         if (cur->right == 0){
           cur->right = node;
           cur = NULL;
         }
         else{
           cur = cur->right;
         }
    node->left = NULL;
    node->right = NULL;
    cout << "Loading CSV file 5555" << endl;
    }
}
}

因为树是空的，所以root是空指针，node也是空指针，因为node=root

首先将要插入的值存储在根节点中是非常奇怪的。 如果您要添加一个节点，代码应该在某个位置显示new node，插入的值应该在该节点中

作为练习，找出在哪里创建它
