    下列程序执行后,变量x的值为______。 Dim a, b, c, d As Single Dim x As Single a=100 b=20 c=1000 If b>a Then d=a: a=b: b=d End If If b>c Then x=b Elseif a>c then x=c Else x=a End If
    A: 100
    B: 20
    C: 1000
    D: 0

      完成以下功能:计算分段函数完成程序。 x2+1 (x<0) y= 2x+1 (0≤x<1) 3x3 (x≥1) Private Sub Command1_Click() Dim y As Single, x As Single x = InputBox("请输入x的值") If x() Then y = x * x + 1 () x < 1 Then y = 2 * x + 1 Else y = 3 * x ^ 3 End If Print x; y End Sub

      下列程序运算后,Label1结果显示的是: Dim x As Integer Dim S As String x = 20 S = "2020" x = x Mod 3 Select Case x Case 0 Label1.Text = "A" Case 1 Label1.Text = "B" Case 2 Label1.Text = "C" Case Else Label1.Text = "D" End Select

      写出下列程序的运行结果。 Private Sub Form_Click() Dim x%, y% x = InputBox("请输入一个整数") If x <= 30 And x > 10 Then If x > 20 Then If x < 25 Then y = 10 Else y = 20 End If Else If x > 15 Then y = 30 Else y = 50 End If End If End If Print y End Sub 假设输入18,则运行结果为

      设有如下两个过程: Private Sub Form_Click() Dim x!,y! x = 18: y = 10 Call PPP((x), y) Print x,y End Sub Private Sub PPP(a As Single, b As Single) a = a + b Print a,b b = a + b Print a,b End Sub 运行程序后, 则输出结果是________
