为什么 要建设网站英迈思网站建设

   本题代码如下（有注释）

void delete_min(linklist* head)
{while ((*head)->next != NULL)//循环到只剩下头节点{lnode* pre = *head;//pre为元素最小结点的前驱结点指针lnode* p = (*head)->next;//p为工作指针lnode* q;//指向被删除的结点while (p->next != NULL)//找到最小的结点{if (p->next->data < pre->next->data)pre = p;//记住当前最小值的前驱p = p->next;}printf("%d ", pre->next->data);//输出最小值结点的数据q = pre->next;//p指向最小结点pre->next = q->next;//pre后继指向q的后继free(q);//释放q结点}free(*head);//释放头节点
}
