Question

我想问下关于VB循环嵌套的语句

本人对此很模糊，麻烦各位帮我详细解析下，不胜感激！
Private Sub Command1_Click( )
Dim i As integer, j As integer
For i=1 to 9
For j=1 to i
Debug.print i*j ; "";
Next j
Debug.print
Next i
End Sub

Answer 1

Private Sub Command1_Click()
'开始command1的click事件

Dim i As Integer, j As Integer
'设置2个整型变量i和j

For i = 1 To 9
'i是从1循环到9

'在每一轮i的循环中,套了一层j的循环

For j = 1 To i
'每次j的循环,是从1到i, 那么i为1时.j将循环1次,一直
'推到i=9时,j就要循环9次了.

Debug.Print i * j; "";
'在立即窗口打印i*j的值,且不换行
Next j
'循环完1轮j

Debug.Print
'在立即窗口换新行
Next i
'结束i循环
End Sub
'结束command1的click事件
