①(Sqr(m))^2=m ②Int(Sqr(m))=Sqr(m)

③m/Int(Sqr(m))= m\Int(Sqr(m)) ④ Int(Sqr(m))^2=m

Dim c As Integer,a(0 To 5) As Integer

For i = 1 To 5

  a(i) = i

Next i

c = 0

For i = 1 To 5

  x = Int(Rnd * 5 + 1)

  If a(x Mod 5) = i + 2 Then c = c + 1

  If c = x Then Exit For

  i = i - 1

Next i

运行该程序后，变量c的值不可能是（  ）

Dim a (1 To 6) As Integer

Randomize

a(1) = Int (Rnd*2) + 1

For i = 2 To 6

  a(j) = Int (Rnd*i) *2 + 1

  If a(i) < a(i-1) Then

    a(i) = a(i) + a(i-1)

  End If

Next i

执行该程序段后，数组元素a(1)到a(6)的值可能是（  ）

count = 0

for i in range(100,991,10) :

    a=i//100

    b=   ①    

    if a==3 or b==3 :

            ②   

        print(i)

print("符合条件的数共有：",count,"个")
