vb九九乘法表左上三角形怎么编程

Answer 1

在按钮的单击事件里写
For i = 1 To 9
For j = 1 To (10 - i)
If (i * j) > 9 Then
Print i & " * " & j & " = " & i * j & " ";
Else
Print i & " * " & j & " = " & i * j & " ";
End If
Next j
Print
Next i

标准三角，不因为算式长短而错位

Answer 2

两个for循环
int i,j;
for(i=1;i<=9;i++)
{
for(j=i;i<=9;j++)
{
Console.Write("{0}*{1}={2}\t",i,j,i*j)
}
Console.WriteLine();
}

....这是c#的 ,反正就两次循环,外面的for循环控制行, 里面嵌套的for循环控制列
