插入到我的链接列表中会导致分段错误,我不确定为什么。这是一个 int 链表。它有时有效,有时则无效。我看不出哪里会出错?也许这与我创建新链表的时间有关。由于链接列表插入最后一个方法在文件读取期间起作用,但在我创建新列表时不起作用。
LinkedList* createLinkedList()
{
LinkedList* list;
list = (LinkedList*)malloc(sizeof(LinkedList));
list->head = NULL;
list->tail = NULL;
list->length = 0;
#ifdef DEBUG
printf("Linked list. Creation of list complete. Checking list length. %d \n", list->length);
#endif
return list;
}
void insertLast(LinkedList* list, int entry)
{
Node* newNode = (Node*)malloc(sizeof(Node));
newNode->data = entry;
/*If list is empty*/
if(list->length == 0)
{
list->head = newNode;
list->tail = newNode;
}
else
{
newNode->prev = list->tail;
/*if this is the second item in the list*/ …Run Code Online (Sandbox Code Playgroud)
