Question

编一个VB程序，输出一个杨辉三角形

也就是说用有关数组的知识编写如下图形：
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1
1 5 10 10 5 1
1 6 15 20 15 6 1
1 7 21 35 35 21 7 1
1 8 28 56 70 56 28 8 1
1 9 36 84 126 126 84 36 9 1
老弟，你说的Debug.是什么意思？我是个VB新手哎，太难懂了

Answer 1

Private Sub Form_Click()
Const N = 10
Dim a(N, N) As Integer
Dim i, j As Integer
a(0, 0) = 1
a(1, 0) = 1
a(1, 1) = 1
For i = 2 To N - 1
a(i, 0) = 1
a(i, i) = 1
For j = 1 To i - 1
a(i, j) = a(i - 1, j - 1) + a(i - 1, j)
Next j, i

For i = 0 To N - 1
For j = 0 To i
Print a(i, j);

Next j

Print

Next i

End Sub

Answer 2

下列代码是用VB6.0实现的,运行后在调试窗口输出
Dim n(1 To 20) As Long, t As Long, i As Long
n(1) = 1
t = 0
Debug.Print 1
For i = 1 To UBound(n)
If i = 1 Then
t = 1
Else
n(i) = n(i) + t
t = n(i) - t
End If
If n(i) = 0 Then
i = 0
Debug.Print
Else
Debug.Print n(i),
End If
Next
