若变量已正确定义,要求程序段完成求5!的计算,不能完成此操作的程序段是()
A. for(i=1; i<=5; i++ )
B. {
C. p=1;
D. p=i;
E. }
F. B.for(i=1,p=1;i<=5;i++) p=i;
G. C.i=1;
H. p=1;
I. while (i<=5 )
J. {
K. p=i;
L. i++;
M. }
N. D.i=1;
O. p=1;
P. do {
Q. p=i;
R. i++;
S. } while (i<=5 )
下列复合语句中,不能实现两数交换的是()
A. {
B. a=b;
C. b=a;
D. }
E. B.{
F. b = a * b;
G. a = b / a;
H. b = b / a;
I. }
J. C.{
K. t=a;
L. a=b;
M. b=t;
N. }
O. D.{
P. a = a + b;
Q. b = a – b;
R. a = a – b;
S. }
程序代码如下:#include
int main()
{
int a,b;
printf(“please input a and b:”);
scanf(“%d%d”,&a,&b);
printf(“the output data is %d”,a7<回车>则程序输出为程序代码如下:#include
int main()
{
int a,b;
printf(“please input a and b:”);
scanf(“%d%d”,&a,&b);
printf(“the output data is %d”,a7<回车>则程序输出为
A. the output data is 7
B. the output data is 2
C. the output data is 1
D. the output data is 0
BookStore数据库中有订单表Order(OrderCode, CustomerCode, TotalPrice, Address, OrderTime, OrderStatus)查询订单总价(TotalPrice)在100到200元之间的订单信息。SQL语句:SELECT OrderCode, TotalPrice, OrderTime, OrderStatus FROM [Order]WH
A. TotalPrice BETWEEN 100 AND 200
B. TotalPrice NOT BETWEEN 100 AND 200
C. 100 <=TotalPrice<=200
D. TotalPrice>=100 And TotalPrice<=200
