商品销售额的实际增加额为5000元，由于零售价格增加使销售额增加了1550元，则由于销售量( )。

A．减少使销售额减少3450元

B．增加使销售额增加3450元

C．减少使销售额减少1000元

D．增加使销售额增加1000元

答案

参考答案：B

解析：销售额的实际增加额=零售价格带来的销售额增加额+销售量带来的销售额增加额本题中，销售额实际增加额为5000元，零售价格使销售额增加了1550元，所以销售量带来的销售额增加额为(5000-1550)=3450元。

填空题

[说明]

已知单链表L含有头节点，且节点中的元素值以递增的方式排列。下面的函数DeleteList在L中查找所有值大于mink且小于maxK的元素，若找到，则逐个删除，同时释放被删节点的空间。若链表中不存在满足条件的元素，则返回-1，否则返回0。

例如，某单链表如下图(a)所示。若令minK为20、maxK为50，则删除后的链表如图(b)所示。

链表节点类型定义如下：

typedef struct Node

int data;

struct Node *next;

Node, *LinkList;

[C函数]

int DeleteList (LinkList L, int minK, int maxK)

/*在含头节点的单链表L中删除大于minK且小于maxK的元素*/

(1) *q=L, *p=L-＞next； /*p指向第一个元素节点*/

int delTag=0;

while (p)

if (P-＞data ＜= minK)

q=p; p= (2) ;

else

if (p-＞data ＜ maxK) /*找到删除满足条件的节点*/

q-＞next= (3) ; free(p);

p= (4) ; delTag=1;

else break;

if ( (5) ) return -1;

return 0;

（1）处应填（）。
