下列代码样例中，哪个存在错误：() A: forfilename in $(ls)do cat $filenamedone B: for((i=0;i<10;i++))do echo $idone C: x=1sum=0while [ $x -le 10 ]do let sum=sum+$x let x=x+1doneecho\ $sum D: for $i in 1 2 3 4 5do echo $idone

下列循环语句中,循环次数最少的是______。 A: a = 5: B: = 7 Do While a < b a = a + 1 LoopB. a = 5: b = 7 Do Until a < b a = a + 1 Loop C: a = 5: b = 7 Do a = a + 1 Loop While a < b D: a = 5: b = 7 Do a = a + 1 Loop Until a < b

DO对对5错A（DO对对5对A）交互式光电感烟探测回路为环形两总线,且每个DO对对5错A探测器内部都有短路隔离开关（）

已知int i=5，下列do while

5 off / do / get / I / where / cinema / for / the / ? ________________

下列程序段的执行结果为（）。i = 4: a = 5Do i = i + 1 a = a + 3Loop Until i >= 9Print i; a

以下能够实现计算5！的程序段是（ ） A: int fac=1,k=0;do{ k++; fac*=k;} while(k<;5);‍ B: int fac=0,k=1;do{ fac*=k; k++;} while(k<;5); C: int fac=1,k=1;do{ k++; fac*=k;} while(k<;=5); D: int fac=1,k=0;do{ fac*=k; k++;} while(k<;5);

5) Ethical values do not vary from person to person.

How do you understand "keep their eyes on the prize" in Paragraph 5?

VAR num reg1:=0 VAR num reg2:=5 以下WHILE循环语句将执行5次循环的有（ ）。 A: WHILE reg1<5 DO …… reg1:=reg1+1; ENDWHILE B: WHILE reg1>5 DO …… reg1:=reg1+1; ENDWHILE C: WHILE reg1 D: WHILE reg1>reg2 DO …… reg1:=reg1+1; ENDWHILE E: WHILE reg1-reg2<0 DO …… reg1:=reg1+1; ENDWHILE
