vb 用inputbox函数输入3个任意整数,安从大到小顺序输出 （块if语句）

Answer 1

Private Sub Form_Click()
Dim a As Single, b As Single, c As Single, z As Single
a = InputBox("输入a的值", "")
b = InputBox("输入b的值", "")
c = InputBox("输入c的值", "")

If a < b Then z = a: b = a: b = z '先把这个较小值给z，把a的值给b，然后把较小值z传递给b，保证a最后存储大的数，b存储较小数
If a < c Then z = a: c = a: c = z '同理，先把这个较小值给z，把c的值给b，然后把较小值z传递给c，保证a最后存储大的数，z存储较小数
If b < c Then z = b: b = c: c = z '再处理b和c，保证b存较大数，c存较小数

Print a; b; c '最后a，b，c就是从大到小排列

End Sub

Answer 2

Dim n(2) As Long, k As Long, i As Integer
For i = 0 To 2
n(i) = Val(InputBox("请输入第" & i + 1 & "个数"))
Next
If n(1) > n(0) Then k = n(0): n(0) = n(1): n(1) = k
If n(2) > n(0) Then k = n(0): n(0) = n(2): n(2) = k
If n(2) > n(1) Then k = n(1): n(1) = n(2): n(2) = k
MsgBox "排序后的结果：" & n(0) & "," & n(1) & "," & n(2)

Answer 3

Private Sub Command1_Click()
Dim a(3) As Integer
For i = 1 To 3
a(i) = InputBox("请输入第" & i & "个数：")
Next i
For i = 1 To 2
For j = i + 1 To 3
If a(i) < a(j) Then
r = a(i)
a(i) = a(j)
a(j) = r
End If
Next j
Next i
For i = 1 To 3
Print a(i);
Next i
End Sub
