VB随机产生30个[10,99]的自然数.

Option Base 1
Dim a(30) As Integer
Private Sub Command1_Click()
Dim max As Integer '储存最大值
Dim min As Integer '储存最小值
Dim sum As Integer '储存总分
Dim n As Integer '储存分数
Dim aver As Integer '平均数
'产生随机数3行10列输出
For i = 1 To 30
Randomize
a(i) = Int(Rnd * 90) + 10
Print a(i);
s = s + 1
If s = 10 Then
Print vbCrLf
s = 0
End If
Next i
max = a(1)
min = a(1)
sum = a(1)
For i = 2 To 30
sum = sum + a(i)
If a(i) > max Then
max = a(i)
End If
If a(i) < min Then
min = a(i)
End If
Next i
sum = sum - max - min
aver = sum / 28
Print max,min,sum
Print "输出去掉最大、最小值后的平均值是：" & aver
End Su
