error: indirection requires pointer operand
提问by jsmith102894
I have the following functions, an initializeHeap function which takes in no arguments and outputs a Heap struct which I have defined. And an insertNode function which takes in a pointer to a heap struct and the number to be added to the heap. I call them in the main function as such:
我有以下函数，一个 initializeHeap 函数，它不接受任何参数并输出我定义的 Heap 结构。还有一个 insertNode 函数，它接收一个指向堆结构的指针和要添加到堆中的数字。我在主函数中这样调用它们：
h = initializeHeap();
Heap *p = *h;
insertNode(p,5);
insertNode(p,7);
insertNode(p,3);
insertNode(p,2);
I get this error when trying to do this:
尝试执行此操作时出现此错误：
error: indirection requires pointer operand
Any ideas? I can post more code if needed.
有任何想法吗？如果需要，我可以发布更多代码。
The struct Heap and function initializeHeap() are as follows:
struct Heap 和函数 initializeHeap() 如下：
typedef struct node{
int data;
}Node;
typedef struct heap{
int size;
Node *dataArray;
}Heap;
Heap initializeHeap(){
Heap heap;
heap.size = 0;
return heap;
}

Change:
改变：
Heap *p = *h;
to
到
Heap *p = &h;
his a Heapstructure object, use &operator to get a pointer to the structure object.
h是一个Heap结构对象，使用&操作符得到一个指向结构对象的指针。
