- 假定x的值为5，则在执行以下语句时，其输出结果为"Result"的正确表示Select Case语句是（ ） A: Select Case x Case 1 To 10 Print "Result" End Select B: Select Case x Case Is＞5,Is＜5 Print "Result" End Select C: Select Case x Case Is＞5,1,3 To 4 Print "Result" End Select D: Select Case x Case 1,3,Is＞5 Print "Result" End Select
- 假设X的值是5，则执行以下语句时，可得到的输出结果是ABCDEF的Select Case语句是 ( ) A: Select Case X Case 10 To 1 Print“ABCDEF” End Select B: Select Case X Case Is＞15，Is＜5 Print"ABCDEF" End Select C: Selecl Case K Case Is＞5，1，3，To 10 Print"ABCDEF" End Select D: Select Case X Case 1，3，Is＞5 Print"ABCDEF" End Select
- 中国大学MOOC: 下列程序的输入值为5，运行结果为（ ）。Private Sub Command1_Click() Dim a As Integer a = InputBox("请输入a的值") Select Case a Case 1 To 4 Print "D" Case 5 To 10 Print "C" Case 11 To 14 Print "B" Case Else Print "A" End SelectEnd Sub
- 设有下面的语句：Print IIf(x＞0, 1, IIf(x＜0,-1, 0))与此语句输出结果不同的程序段是______。 A: If x＞0 Then x=1 ElseIf x＜0 Then x=-1 End If Print x B: If x＞0 Then Print 1 ElseIf x＜0 Then Print-1 Else Print 0 End If C: Select Case x Case Is＞0 Print 1 Case Is＜0 Print-1 Case Else Print 0 End Select D: If x＜＞0 Then If x＞0 Then Print 1 ElseIf x＜0 Then Print-1 Else Print 0 End If
- 以下程序段中，执行结果与其他3个选项不同的是 A: Dim y As Integer B: y = 11 C: Select Case y D: Case 15 To 5 E: Print "Executed" F: End Select G: Dim y As Integer H: y = 10 I: Select Case y J: Case Is > 10, Is < 10 K: Print " Executed " L: End Select M: Dim y As Integer N: y = 10 O: Select Case y P: Case Is > 15, 1, 5 To 8 Q: Print " Executed " R: End Select S: Dim y As Integer T: y = 10 U: Select Case y V: Case 1, 3, Is > 6 W: Print " Executed " X: End Select
