我的函数remove_duplicates应该删除链接列表中的重复数据值。但是,当它到达链接列表中的某个点时,例如,如果链接列表是L = {10,10,20,30,30,30,40,50}
,则输出为L = {10,20,30,(some random int value like 23687328),50}
,应该是L = {10,20,30,40,50}
。另外,我正在检查泄漏情况,Valgrind告诉我我在某处泄漏,但我找不到它。释放和删除链接列表中的重复项?
typedef struct node_t
{
int data;
struct node_t *next;
} node;
void remove_duplicates(node * head)
{
node* temp;
while (head != NULL && head->next != NULL)
{
while (head->data == head->next->data)
{
temp = head->next->next;
free(head->next);
head->next = temp;
}
head = head->next;
}
free(temp);
}
我使用的valgrind --leak检查= YES ./llistprac和输出
==24802== 80 (16 direct, 64 indirect) bytes in 1 blocks are definitely lost in loss record 5 of 5
==24802== at 0x4A069EE: malloc (vg_replace_malloc.c:270)

有趣的是(至少对我来说),当我最终没有释放温度时,它就起作用了!但是,我仍然在泄漏...... – Bourezg
当你说Valgrind告诉你你正在泄漏,但你找不到它时,你使用什么参数以及Valgrind输出是什么? – kbshimmyo
你不应该需要释放温度。 – Duck
