If x > 3 Then

   If x <= 6 Then

     y = 2 * x

   Else

     y = 3 * x

Print y若x、y均是整型变量，程序运行并输入6，则y的值是（   ）

执行程序时，在文本框 Text1 中输入“12+34=46!789ok”（不包括双引号），单击按钮Command1后，在列表框List1中显示的结果是（  ）

    a(1) = 1

    For i = 2 To 12

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

    Next i

    i = 1: j = 12: cnt = 1: flag = False

    Do While i <= j And flag = False

      cnt = cnt + 1

      m = (i + j + 1) \ 2

      If a(m) = Key Then

程序运行后，下列说法正确的是（  ）
