Question

在下面的代码中，我在编译时在add_node函数中遇到问题。

我收到与以下代码行有关的错误：struct *node pNode = (struct node*)malloc(sizeof(struct node))

任何建议都将不胜感激。

struct list
{
   struct node *head;
   int count;
};

struct node *add_node(struct list *pList, float coef, int expo)
{
    if (pList == NULL)
    {
        return NULL;
    }

    struct *node pNode = (struct node*)malloc(sizeof(struct node));

    if (node == NULL)
    {
         return NULL;
    }

    pNode->coef = coef;
    pNode->expo = expo;
    pNode->link = pList->head;

    pList->head = pNode;
    pList->count++;

    return pNode;
}

Answer 1

制作本

struct *node pNode = (struct node*)malloc(sizeof(struct node));

到

struct node *pNode = (struct node*)malloc(sizeof(struct node));

Answer 2

您可能想将该行更改为struct node * pNode =（struct node *）malloc（sizeof（struct node））;

Answer 3

更改

if (node == NULL)

到

if (pNode == NULL)
