PNODE pHead = (PNODE)malloc(sizeof(NODE));if (NULL == pHead){printf("分配失败, 程序终止!\n");exit(-1);}PNODE pTail = pHead;pTail->pNext = NULL;
printf("请输入您需要生成的链表节点的个数: len = ");scanf("%d", &len);for (i=0; i<len; ++i){printf("请输入第%d个节点的值: ", i+1);scanf("%d", &val);PNODE pNew = (PNODE)malloc(sizeof(NODE));if (NULL == pNew){printf("分配失败, 程序终止!\n");exit(-1);}pNew->data = val;pTail->pNext = pNew;pNew->pNext = NULL;pTail = pNew;
在这里pTail指向了pHead，然后pTail指向 pNew，为什么pHead也指向 pNew了
