How to solve this error?

它在前面的链表列表中我已经正确地声明了所有内容并在c中实现但是我无法得出结果。

  

我正在研究基本的，当我尝试这个我无法得到答案我跟着我的代码Skool的视频，但没有为我工作

Answer 1

用这个修改插入函数： - `

void insert(int num)
{
    if(head==NULL)
    {
        struct Node* temp = (struct Node*)malloc(sizeof(struct Node));
        temp -> data = num;
        temp -> next = NULL;
        head = temp;
    }
    else
    {
        struct Node* temp1 = (struct Node*)malloc(sizeof(struct Node));
        temp -> data = num; 
        temp -> next = head;
        head = temp;
    }
}
