在n个运动员中选出任意r个人参加比赛，有很多种不同的选法，选法的个数可以用公式(作图)计算，在窗体上设计3个文本框，名称依次是Text1、Text2、Text3。程序运行时在Text1、Text2中分别输入n和r的值，单击Command1按钮即可求出选法的个数，并显示在Text3文本框中，请在空白处填入适当语句使程序完整。
Prvate Sub Command1_C1ick()
Dimr As Integer,n As Integer
n＝Text1
r＝TeXt2
Text3＝fun(n))(______))fun(r)
End Sub
Function fun(n As Integer)As long
Dim t AS Long
For k＝1 To n
t＝t*k
Next k
fun＝t
End Function
