Dim n As Integer, i As Integer, a As Integer, b As Integer

Randomize

n=5：i=1

Do While i <=n

a= Int(Rnd*90)+ 10

b= Int(Rnd*90)+ 10

If a>b Then

List1.AddItem Str(a)+"-"+ Str(b)+“=“

i=i+1

End If

Loop

执行该程序段后，下列说法正确的是（  ）

a(I)=68: a(2)=88: a(3)=76: a(4)= 60: a(5)=98: a(6)=100: a(7)= 64: a(8)=85: a(9)=99: a(10)=59

  For i=1 To 9

    b(i)=Abs(a(i+1)-a(i))

    c(b(i)\10)= c(b(i)\10) + 1

  Next i

  For i=0 To 10

    If c(i)> 0 Then Label1.Caption = Label1.Caption + "" + Str(c(i))

Next i

数组c各元素初值为0，执行该程序段，标签Label 1上显示的内容是（  ）
