If ss(i) <> 0 Then Print ss(i) avera = avera + ss(i) Next i

Picture1.Print avera End Sub

Function ss(n) As Integer Dim i%, tag As Boolean tag = True

For i = 3 To n / 2

If (n Mod i) = 0 Then tag = False Next i

If tag Then ss = n End Function

13：.编一冒泡程序，对已知整数按递减次序排列，用子过程 Sub sort(a())

Dim imin%, i%, j%

For i = 0 To UBound(a) - 1

For j = 0 To UBound(a) - 1 - i If a(j＋1) > a(j ) Then

t = a(j): a(j) = a(j + 1): a(j + 1) = t End If Next j Next i End Sub

Private Sub Form_Click() Dim b(), i%

b = Array(8, 9, 4, 2, 6) Call sort(b())

For i = 0 To UBound(b) Print b(i); Next i End Sub

14.用选择排序法子过程对已知的若干整数按递增次序排列 Sub sort(a())

Dim imin%, i%, j%

For i = 0 To UBound(a) - 1 imin = i

For j = i + 1 To UBound(a) If a(j) < a(imin) Then imin = j Next j

t = a(i): a(i) = a(imin): a(imin) = t Next i

End Sub

Private Sub Form_Click() Dim b(), i%

b = Array(8, 9, 4, 2, 6) Call sort(b())

For i = 0 To UBound(b) Print b(i); Next i End Sub
