while(p->next)p=p->next;

while(p->next)p=p->next; 在数据结构中 LinkList *p=L->next;While(p! While(p->next)求解释 下面的while(p)和if(p)的具体意思int ListLength_L(LinkList &L){int i=0;LinkList p=L;if(p) p=p-next;while(p){p=p->next;i++;}return i;} 两题单链表逆置,求讲解1.p=head->next;head->next=NULL;while(p){s=p;p=p->next;s->next=head->next;head->=s;}p=head-next;2.p=head->next;q=p->next;p->next=NULL;while(q!=NULL){r=q->next;q->next=p;p=q;q=r;} head->next=p；本人初学数据结构, 简述以下算法功能Status A(Linkedlist L){if(L&&L->next){Q=L;L=L-next;P=L;while(P->next)P=P->next;P->next=Q;Q->next=NULL;}return OK;}//A node *mergelink(node *p,node *q){node *h,*r;h = (node*) malloc (sizeof(node));h->next = NULL;r = h;while (p = NULL && q = NULL){if (p->data data){r->next = p;r = p;p = p->next;}else{r->next = q;r = q;q = q->next;}}if (p == NULL)r->next = q;if (q == N 在循环双链表的p所指节点之后插入s所直接点操作A,p->next=s;s->prior=p;p->next->prior=s;s->next=p->next;B.p->next=s;p->next->prior=s;s->prior=p;s->next=p->next;C.s->prior=p;s->next=p->next;p->next=s;p->next->prior=s;D.s->prior=p;s->n 带头单链表逆置,下面程序有错吗?p=head->next;q=p->next;什么意思?void linklist_rev1(linklilst head); p=head->next;head->next=NULL;while(p){q=p->next;p->next=head->next;head->next=p;p=q;} C语言 数据结构与算法分析C语言描述里面的Position P Position是一个类型么void DeleteList (List){Position P;P = L -> Next;while ( P = NULL){free (P);P = P -> Next;}} L为无表头结点的单链表,p既不是首元结点也不是表尾结点,在p结点前插入s结点.q=p;p=L;while(p->next!=q)p=p->next;s->next=p->next;p->next=s;我怎么看这是在p结点后面插入s啊,小弟不解,求指教. while(*p&&*p=='*')什么意思 C语言链表中q->next=p;表示什么意思?while (q) {r=q->next; q->next=p; p=q; q=r; } while(fabs(p)>e) { p*=y/n; sum +=p; n++; } 解释一下 sum +=p是不是等于sum=sum+p return0;p=p->next;printf(Sorry!structproduct*p;gotoagain; 数据结构中P->next=P和P=P->next的区别? p->next=p;和p=p->next;有什么区别? void fun (SLIST *h,int x){ SLIST *p,*q,*s;s=(SLIST*) malloc (sizeof (SLIST)); s->data=x;q=h;p=h->next;while(p!=NULL && x>p->data) {q=p;p=p->next;}s->next=p;q->next=s;}
