冀教版八年级第三单元程序设计-VB单元测试
s=0
For i=5 to -3 step-6
s=s+i
Next i
s='t1Hr2a3'
s1='' ; s2=''; i = 0
while i < len(s):
if '0'<=s[i]<='9':
s1 = s1 + s[i]
elif 'a'<=s[i]<='z':
s2 = s[i] + s2
i = i + 1
ans = s2 + s1
print(ans)
程序执行后,输出的结果是( )
s=0 : t=1: p=1
For i=1 To 10
t=t*i
s=s+p*t
p=- p
i = 5
sum = 0
while i <= 10:
sum = sum + i
print(sum)
程序输出值是:{#blank#}1{#/blank#}。
