Question

一道vb题（懂的解） n=0 For i=1 To3 For j=5 To 1 step -1 n=n+1 Next j

Answer 1

如果按以下格式：

Private Sub Form_Load()

n = 0

For i = 1 To 3

For j = 5 To 1 Step -1

n = n + 1

Text3.Text = Text3.Text & vbCrLf & n & " - " & j & " - " & i

Next j

Next i

End Sub

结果是：n-j-i

1 - 5 - 1

2 - 4 - 1

3 - 3 - 1

4 - 2 - 1

5 - 1 - 1

6 - 5 - 2

7 - 4 - 2

8 - 3 - 2

9 - 2 - 2

10 - 1 - 2

11 - 5 - 3

12 - 4 - 3

13 - 3 - 3

14 - 2 - 3

15 - 1 - 3

如果按以下格式：

Private Sub Form_Load()

n = 0

For i = 1 To 3

For j = 5 To 1 Step -1

n = n + 1

Next j

Next i

Text3.Text = Text3.Text & vbCrLf & n & " - " & j & " - " & i

End Sub

结果是：n-j-i

15 - 0 - 4
