1、题目:(事件)单击窗体(响应)用输入框输入一自然数,判断是"正数"、"负数或"零",并根据输入的数用消息框显示"正数"、"负数”或"零"。
1题
n = InputBox("输入一个自然数")
If n > 0 Then
result = "正数"
ElseIf n < 0 Then
result = "负数"
ElseIf n = 0 Then
result = "零"
End If
MsgBox "输入的数据" & n & "为:" & result
3题
Dim i As Integer
s = 0
For i = 1 To 10
s = s + 1 / (i ^ i)
Next

7题
Dim a(9) As Integer
Dim i, s As Integer
a(0) = 15:a(1) = 23:a(2) = 72
a(3) = 43:a(4) = 96:a(5) = 23
a(6) = 3:a(7) = 65:a(8) = 88
a(9) = 17:max = a(0):min = a(0)
s = 0
For i = 0 To 9
If a(i) > max Then
max = a(i)
End If
If a(i) < min Then
