用vb.net2008打印楊輝三角形(打印10行),要求如圖所示？

Public Class Form1

Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click

Dim n As Integer, i As Integer, j As Integer, a(,) As Integer

n = 10

ReDim a(n + 1, n + 1)

For i = 1 To n + 1

a(i, 1) = 1 : a(i, i) = 1 : Next i

For i = 3 To n + 1

For j = 2 To i - 1

a(i, j) = a(i - 1, j - 1) + a(i - 1, j)

Next j, i

For i = 1 To n + 1

For j = 1 To i

TextBox1.AppendText(Space(4 - Len(Trim(Str(a(i, j))))) Trim(Str(a(i, j))))

Next j

TextBox1.AppendText(vbCrLf)

Next i

End Sub

End Class,9,

謝謝了，但是你寫的代碼可以輸出多少行？多久會溢出了

舉報 ccddty

沒試過，你可以試試，將n的值加大 當(dāng)n》16的時候就顯示“參數(shù)“Number”必須大于或等于 0?！绷?有沒有辦法解決？,

VB.Net的問題，輸入整數(shù)n，顯示具有n行的楊輝三角形。

參考：

以下為十行的楊輝三角輸出，根據(jù)這個自己做相應(yīng)修改，都做好了，那你就是伸手黨了。
