实验E数组和自定义类型(精)

1、实验E :数组和自定义类型 目的掌握数组的概念；体会数组在处理有序数据方面的优越性；掌握数组的常用解题算法。 内容教材中实验：1、2、3、4、5、61、Private Sub Form_Click(Dim a(1 To 10 As In teger, i%, maxa%, min a%, avera!For i = 1 To 10a(i = Int(Rnd * 100Next imina = a(1maxa = a(1avera = a(1For i = 2 To 10If a(i maxa The n maxa = a(iIf a(i mi na The n mi na = a(iavera
