显示系统当前日期和时间

有如下Visual Basic程序段：
Dim a(1 To 7) As Integer, i As Integer, j As Integer, k As Integer, c As Integer
a(1) =" 3:" a(2) =" 9:" a(3) =" 1:" a(4) =" 5:" a(5) =" 8:" a(6) =" 6:" a(2) = 2
s = ""
For i =" 1" To 3
For j =" i" + 1 To 7
If a(j) < a(i) Then
k =" a(j):" a(j) =" a(i):" a(i) = k
c =" c" + 1
End If
Next j
s =" Str(a(i))" + s
Next i
text1.Text =" Str(c)" & “:” & s
该程序段运行后,文本框Text1中显示的内容是

A．5:6 8 9

B．3: 9 8 6

C．3:1 2 3

D．5:3 2 1

有一组数：1、2、4、7、……，其第1个数是1，第2个数比第1个数大1，第3个数比第2个数大2，第4个数比第3个数大3，以此类推。求其前20项的和。
以下VB程序实现上述功能，请把程序中的①、②出填写完整。
Dim i As Integer, p As Integer, s As Integer
i = 1
p = 1
s = 0
Do While ______①______
s =" s" + p
i =" i" + 1
______②______
Loop
Print s

Print  “ANB”+STR(1223)的输出结果为_____。
