VB数组问题
如下数组声明语句，则数组a包含元素的个数有______。
Dim a(3, 2 to 2,5)
（A）120 （B）75
（C）60 （D）13
要解答过程，原理

Answer 1

窗体上建立两个按钮,两个文本框
Private Sub Command1_Click()
Dim i As Integer, s As Integer, aver As Single
Dim myarray(1 To 10)
For i = 1 To 10
myarray(i) = i '数组赋值
s = s + myarray(i) '求和
Next i
aver = s / 10 '求平均值
Text1.Text = aver
End Sub
Private Sub Command2_Click()
Dim i As Integer, s As Integer, aver As Single, x As Integer
Dim DYarray() As Integer
x = InputBox("请输入一个值,它是元素个数", "元素个数")
ReDim DYarray(1 To x)
For i = 1 To x
DYarray(i) = InputBox("请输入第" & i & "个元素", "输入每个元素") '数组赋值
s = s + DYarray(i) '求和
aver = s / x '求平均值
Next i
Text2.Text = aver
End Sub
