今天晚上,可以才说是放暑假来安安的学习了一波,当然时间也没有很长,毕竟在暑假中。 最近都没有来写博客,读书也读的好慢呢。为什么呢? 从开始学车到今天已经将近20天的时间了,后来都是只有早上去练,中午饭吃了后就自由安排咯。 虽说是自由安排,细细想想中午饭吃了然后午休就直接到三点,这个尴尬的时间起来,大部分都是出去和朋友们娱乐去了。晚上打完球或者娱乐完后回家,冲个澡就直接扑倒在床上,看会视频直播
请进来认真看,到底为什么不行?

帮忙看一个函数!
学习数据结构写了一个带头节点的双向链表,中间节点和头节点的定义如下:rntypedef struct DLnodernrn Item elem; rn struct DLnode *pre; rn struct DLnode *next; rn DLnode_head *list; // on which list we arernDLnode;rntypedef struct DLnode_headrnrn struct DLnode *pre; // point to the previous nodern struct DLnode *next; // point to the next nodern struct DLnode *tail; // point to the last node of the listrn int qlen; // record the len of the listrnDLnode_head;rnrn链表销毁函数如下:rnvoid destory_list(DLnode_head **list)rnrn rn DLnode *start,*next;rn start = (*list)->next;rn next = start->next;rn rn while( start != NULL )rn rn rn rn free(start);rn start = next;rn next = start->next;rn rn rn free(*list);rn rn *list = NULL;rnrn这个销毁函数的实现编译通过,但是运行时就出错了,不知道错在哪里但是如果写成下面的样子就对了,我感觉两个是一样的啊,为什么会得到不同的结果呢?rnvoid destory_list(DLnode_head **list)rnrn rn DLnode *start,*next;rn start = (*list)->next;rn rn while( start != NULL )rn rn rn next = start->next;rn free(start);rn start = next;rn rn rn rn free(*list);rn rn *list = NULL;rnrnrn

请大家帮忙看段程序
