有以下结构体说明和变量的定义,且指针p指向变量a,指针q指向变量b,则不能把节点b连接到节点a之后的语句是( )。 struct node { char data; struct node *next; }a,b, *p=a,*q=b;A.a.next=q;B.p.next=b;C.p->next=bD.(*p).next=q;
[说明]已知包含头节点(不存储元素)的单链表的元素已经按照非递减方式排序,函数compress(NODE *head)的功能是去掉其中重复的元素,使得链表中的元素互不相同。处理过程中,当元素重复出现时,保留元素第一次出现所在的节点。图8-29(a)、(b)是经函数compress( )处理前后的链表结构示例图。链表的节点类型定义如下:typedef struct Node {int data;struct Node *next;}NODE;[C语言函数]void compress(NODE *head){NODE *ptr, *q;ptr= (1) ; /*取得第一个元素节点的指针*/while( (2) ptr->next) {q=ptr ->next;while(q (3) ){/*处理重复元素*/(4) =q ->next;free(q);q=ptr->next;}(5) =ptr->next;} /*end of while*/} /*end of compress*/
