以下有关数组定义的语句序列中，错误的是______。 A: Static arr1(3)arr1(1)=100arr1(2)="Hello"arr1(3)=123.45 B: Dim arr2() As IntegerDim size As IntegerPrivate Sub Command2_Click()size=InputBox("输入:")ReDim arr2(size)……End Sub C: Option Base 1Private Sub Command3_Click()Dim arr3(3) As Integer…… End Sub D: Dim n As IntegerPrivate Sub Command4_Click()Dim arr4(n) As Integer……End Sub

运行下面的程序，第二行显示结果是___________。 Private Sub Form_Click() Dim A As Integer Dim i As Integer A = 5 For i = 1 To 9 Call sub1(i, A) Print i, A Next i End Sub Private Sub sub1(x As Integer, y As Integer) Static N As Integer Dim I As Integer For I = 3 To 1 Step -1 N = N + x x = x + 2 Next I y = y + N End Sub

求给定自然数m和n的最大公约数。请完善程序。 Private Sub Command1_Click() Dim m As Integer, n As Integer, r As Integer m = Text1.Text n = Text2.Text If m < n Then r = m: m = n: n = r Do r = m Mod n m = n n = r Loop Until__________ Text3.Text = m End Sub Private Sub Command2_Click() Dim m As Integer, n As Integer, r As Integer m = Text1.Text n = Text2.Text If m < n Then r = m: m = n: n = r r = m Mod n Do Until _______ m = n n = r r = m Mod n Loop Text3.Text =____ End Sub Private Sub Command3_Click() Dim m As Integer, n As Integer, r As Integer m = Text1.Text n = Text2.Text If m < n Then r = m: m = n: n = r Do r = m Mod n m = n n = r Loop While________ Text3.Text =______ End Sub Private Sub Command4_Click() Dim m As Integer, n As Integer, r As Integer m = Text1.Text n = Text2.Text If m < n Then r = m: m = n: n = r r = m Mod n Do While______ m = n n = r r = m Mod n Loop Text3.Text =____ End Sube73f1fd63959cc8362d8c82d419c2353.png

设有如下程序： Option Base 1 Private Sub Command1 Click() Dim a(10) As Integer Dim n As Integer n=InputBox(“输入数据”) If n＜ 10 Then Call，GetArray(a， n) End If End Sub Private Sub GetArray(b() As Integer， n As Integer) Dim c(10)As Integer j=0 For i=1 To n b(i)=CInt(Rnd()*100) If b(i) /2 =b(i) \2 Then j=j + 1 c(j) = b(i) End If Next Print j End Sub 以下叙述中错误的是 A: 数组b中的偶数被保存在数组c中 B: 程序运行结束时，在窗体上显示的是c数组中元素的个数 C: GetArray过程的参数n是按值传送的 D: 如果输入的数据大于10，则窗体上不显示任何信息

运行下列程序，单击窗体显示的结果为（ ）。 Private Sub Form_Click() Dim a Dim s As Integer, i As Integer a = Array(1, 2, 3) For i = 2 To 0 Step -1 s = s + a(i) * a(i) Next i Print s End Sub
