Dim i As Integer, s As Integer

i = 1

s = 0

Do While i <= 5

 s = s + 2

i = i + 1

Loop

问：该程序段运行后，变量s的值为{#blank#}1{#/blank#}，i的值为{#blank#}2{#/blank#}。

a＝2

b＝1

Do While b<＝4

 a＝a＋b

 b＝a＋b

Loop

Text1.Text＝Str(a＋b)

则运行该程序段后，文本框Text1上显示（  ）

为实现上述功能，请将以下程序补充完整。

Private Sub Command1_Click()

Dim j As Integer, k As Integer

List1.Clear

For k = 1 To 100

    j = Int(Sqr(k))

    If {#blank#}1{#/blank#}Then List1.AddItem {#blank#}2{#/blank#}

Next k

End Sub

>>>  a=3

>>>  b=6

>>>  a, b=b, a

>>>  a-=b

>>>  a+b

a=a-b

a=a*b
