下面的程序随机产生10个小于100的整数，并找出其最大值、最小值和平均值，请将程序补充完整。(此程序是VB语言编写)
Private Sub Form_Click( )
Dim a(1 To 10)As Integer
Dim m_max As Integer, m_min As Integer
Dim s As Single
Randomize
For i=1 To 10
a(i)=______
Print a(i)
Next i
m max=0: m min=100
For i=1 To 10
If a(i)＞m_max Then______
If a(i)＜m_min Then m min=a(i)
s=______
______
Print"最大值是:"; m_max
Print"最小值是:"; m_min
PIint"平均值是:"; ______
End Sub
