举一反三
- 编写如下程序: Private Sub Command1_Click() Dim x As Integer, y As Integer x = 1: y = 1 Do y = x * y If y > 10 Then Print x, y Exit Do Else x = x + 3 End If Loop While x <= 10 End Sub 运行程序,输出结果为______
- 执行下列程序段后,变量y的值为( )。 Dim x As Integer,y As Integer x = 7 y = 3 If x >= 10 Then y = x - y ElseIf x>= 7 Then y = x + y Else y = x End If A: 21 B: 10 C: 4 D: 3
- 有如下事件程序,运行该程序后输出结果是。 Private Sub Command33_Click() Dim x As Integer, y As Integer x = 1: y = 0 Do Until y <= 25 y = y + x * x x = x + 1 Loop MsgBox "x=" & x & ", y=" & y End Sub
- Sub s1(ByVal x As Integer, ByVal y As Integer) Dim t As Integer t = x: x = y: y = t End Sub Sub s2(x As Integer, y As Integer) Dim t As Integer t = x: x = y: y = t End Sub 则以下说法中正确的是( )。
- 中国大学MOOC: 下面的程序执行完后a,b的值分别为______。 Dim x, y, a, b As Integer x = 12 : y = 8 a = 1 : b = x * y Do While x Mod 2 = 0 And y Mod 2 = 0 x = x 2 y = y 2 a = a * 2 Loop Do While x <> y If x > y Then x = x - y Else y = y - x End If Loop a = a * x b = b a

下面哪些定义是类型正确的? A: f :: (Integer, Integer) - Floatf (x,y) =x / y B: f :: (Integer, Integer) - Floatf (x,y) = (fromInteger x) / (fromInteger y) C: f :: (Integer, Integer) - Floatf (x,y) = 3*x + y D: f :: (Integer, Integer) - Integerf (x, y) = 3*x + y

有如下事件程序,运行该程序后输出结果是_________。 Private Sub Command33_Click() Dim x As Integer, y As Integer x=1:y=0 Do Until y<=25 y=y+x*x x=x+1 Loop MsgBox "x=" & x &",y=" & y End Sub A: x=1,y=0 B: x=4,y=25 C: x=5,y=30 D: 输出其他结果

设有如下通用过程,在窗体上画一个名称为command1的命令按钮,然后编写如下事件过程: private sub command1_click() dim x as integer x=10 y=5 y=f(x) print x;y end sub public function f (x as integer) dim y as integer x=20 y=2 f=x*y end function 程序运行后,如果单击命令按钮,则在窗体上显示的内容是()

下列Python语句正确的是( ) A: min = x if x <; y else y B: max = x >; y ? x : y C: if x <; y print x D: if (x >; y) print x
