1. (2020高三下·浙江开学考) 有如下VB程序段：

Dim a(1 To 10) As Integer

Dim i, j As Integer

For i = 1 To 10

    j = i

    Do While j <= 10

        If j Mod i = 0 Then

            a(j) = a(j) + 1

        End If

        j = j + 1

    Loop

Next i

Text1.Text = Str(a(3))

数组a各元素初值为0，执行上述程序段后，文本框Text1中显示的内容为（    ）
