  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（  ）

Private Sub Command1_Click()

    Dim a As Integer, b As Integer

    Dim c As Integer                     '①

    a= Val(Text1. Text)                     '②

    b = Val(Text2. Text)

    c=a + b                             '③

    Label1. Caption ="a + b="+c        '④

End Sub

res =s[0]

for i in range(1,len(s)):

    if s[i] >= res:

        res =s[i]

print(res)

执行上述程序后，输出的结果是（   ）
