Dim a(1 To 100) As Integer

Dim b(1 To 100) As Integer

Dim c As Integer

a(1) = 0: a(2) = 2: b(1) = 1: b(2) = 2: c = 0

For i = 2 To 6

  a(i + 1) = 2 * a(i) - a(i - 1)

  b(i + 1) = b(i) ^ 2 / b(i - 1)

c = c + a(i + 1) + b(i + 1)

Next i

Label1.Caption = Str(c)

该程序运行后，Label1中显示的内容是（  ）

下列说法不正确的是（  ）

执行这部分流程后，变量x的值是（  ）

    key = Val(Text1.Text)

i = 1: j = n * 2 : flag = False

   Do While i + 1 <= j And Not flag

     m = (i + j) \ 2

     If     ①     Then m=m-1

     If a(m) = key Or a(m + 1) = key Then

        flag = True

     ElseIf a(m) > key Then

               ②       

     Else

               ③      

     End If

   Loop

   If a(i) = key Or a(j) = key Then flag = True

   If flag Then Label1.Caption = "yes" Else Label1.Caption = "no"

划线处的代码正确的是（  ）
