如下数组声明语句，正确的是______。 A: Dim a%(,) B: Dim b%(4) = {1, 2, 3, 4, 5} C: Dim c%(-2) D: Dim d%{{1, 2, 3}, {4, 5, 6}}

下列数组声明语句，________是正确的。 A: Dim a(2,3) As Integer B: Dim a(m,n) As Integer C: Dim a(2 3) As Integer D: Dim a[3,2] As Integer

2、设A 为线性空间V上的线性变换，则dim(ker(A))+dim(Im(A))= .

下面的数组声明语句中，正确的是_____。 A: Dim a[1，2] As Integer B: Dim a（1，2） As Integer C: Dim a[1] [2] As Integer D: Dim a（1 to 0，2 to 0） As Integer

下列数组声明语句中，不正确的是_________。 A: Dim a(3) As Single = {0, 1, 2, 3} B: Dim a%(3) C: Dim a(1, 4) As Single D: Dim a(4) As Single

下列数组声明语句中，不正确的是_________。 A: Dim a(9) As Single = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} B: Dim a() = {1, 2, 3, 4, 5, 6, 10} C: Dim a( ,) As Single = {{1, 2, 3, 4, 5}, {6, 7, 8, 9, 10}} D: Dim a() As Single = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} E: Dim n As Integer=10Dim a(n) As Single

下列程序段的运行结果为（）。 Dim a Dim s%, i% a = Arra...) ^ 2 Next i Print s

如下程序执行后，应用程序界面显示的是： Dim a As Integer = 2 Dim b As Integer = 3 Dim c As Single = 2 If a < b Then If a < c Then c = c - 1 Else c = c + 1 End If End If Label1.Text = c.ToString

已知：Option Base 0，Dim a() As Integer, Dim b(-1 to 2) As Integer，如果执行 a = b ，则数组a的下界是

下列定义画笔对象p的语句中，正确的是___________。 A: Dim p As new Pen = Color.Red B: Dim p As Pen = New Pen(Color.Red, 3) C: Dim p As new Pen = Pen(Color.Red，1) D: Dim p As Pen(Color.Black) E: Dim p = Pen(Color.Black,2)
