C++ 指向指针解引用的指针；编译器请求'-&燃气轮机'；

我编写了一个简单的函数，将一个子列表插入到引用给出的链表中。代码看起来对我来说是正确的，但编译器指示我没有正确使用指针

void insertSub(string h, day d, string gr, string sub, ListAPI **tmp_api) {
  auto newNode = new _ListSub;

  // initialize new node of sub-list
  newNode->h = h;
  newNode->d = d;
  newNode->gr = gr;
  newNode->sub = sub;

  // point new node to the previous and next node
  newNode->next = node->next;
  newNode->prev = node;

  // point actual node to the new node
  *tmp_api->head->next->prev = newNode;
  *tmp_api->head->next = newNode;

  cout << "New node inserted to " << *tmp_api->id << endl;

  // increment size
  ++ node->size;
}

其中

api

属于

ListAPI*

类型，并且不包含节点

g++错误：

cout如图所示，
->
运算符的优先级高于
*
运算符，因此首先对其求值。使用
（*temp\u api）->head

我们需要了解您如何定义
ListAPI
，但是
head
将成为结构的成员似乎有些奇怪。建议：将代码与以下示例进行比较：。您有运算符优先级问题。编写
（*tmp_-api）->head
