Private Sub Command1_Click()
Dim a(10) As Integer
Dim max As Integer
Dim min As Integer
Dim avg As Double
Dim sum As Integer
sum = 0
Randomize
For i = 1 To 10
If i = 1 Then
a(i) = Int(Rnd * 90 + 10)
max = a(i)
min = a(i)
sum = sum + a(i)
Else
a(i) = Int(Rnd * 90 + 10)
If a(i) > max Then max = a(i)
If a(i) < min Then min = a(i)
sum = sum + a(i)
End If
Next i
Print "最大值是" & max
Print "最小值是" & min
Print "平均值是" & sum / 10
End Sub
