3、选择题:有如下函数过程:Function secproc(x As Integer, y As Integer, z As Integer) secproc = 3 y + z + 2 xEnd Function Private Sub Command1_Click() Dim a As Integer, b As Integer, c As Integer a = 2: b = 3: c = 4 Print secproc(c, b, a)End Sub该程序的运行结果是( )。
选项:
A:17
B:18
C:19
D:20
我的答案: 【19】
4、选择题:有如下函数过程:Function Cys(ByVal x As Integer, ByVal y As Integer) As Integer Dim quotients Do While y <> 0 quotients = x / y x = y y = quotients Loop Cys = xEnd Function以下是调用该函数的事件过程,该程序的运行结果是( )。Private Sub Command1_Click() Dim a As Integer Dim b As Integer a = 10 b = 2 x = Cys(a, b) Print xEnd Sub
选项:
A:0
B:25
C:5
D:100
我的答案: 【5】
5、选择题:以下是一个能返回数组a中最大数的函数过程代码: Function maxval(a() As Integer) As Integer Dim max% max = 1 For i = 2 To 10 If a(i) > a(max) Then max = i Next i maxval = max End Function Private Sub Command1_Click() Dim x(1 To 10) As Integer For i = 1 To 10 x(i) = Int(Rnd() 100) Print x(i); Next i Print Print maxval(x())End Sub程序运行时,发现函数过程的返回值是错的需要修改,下面的修改方案中正确的是( )。
选项:
A:语句“max = 1”应改为“max = a(1)”
B:语句“For i = 2 To 10”应改为“For i = 1 To 10”
C:If语句“max = i”应改为“max = a(i)”
D:语句“maxval = max ”应改为“maxval = a(max)”
我的答案: D
6、选择题: 在窗体上画一个命令按钮(名称为Command1),并编写如下代码:Function Fun1(ByVal a As Integer, b As Integer) As Integer Dim t As Integer t = a – b b = t + a Fun1 = t + bEnd Function Private Sub Command1_Click() Dim x As Integer x = 10 Print Fun1(Fun1(x, (Fun1(x, x – 1))), x – 1)End Sub程序运行后,单击命令按钮,输出结果是( )。
选项:
A: 10
B: 0
C: 11
D: 21
我的答案: B
7、选择题:下面程序的运行结果为( )。Dim a%, b%, c%Sub p1(x%, y%) Dim c As Integer x = 2 x: y = y + 2: c = x + yEnd SubSub p2(x%, ByVal y%) Dim c As Integer x = 2 * x: y = y + 2: c = x + yEnd SubPrivate Sub Command1_Click() a = 2: b = 4: c = 6 Call p1(a, b) Call p2(a, b) Print a; b; cEnd Sub
选项:
A: 4 6 6
B: 8 6 6
C: 4 6 10
D: 8 8 6
我的答案: 【8 6 6】
8、选择题:下面程序:Function a(x) Static b As Integer b = b + x ^ 2 Print bEnd Function Private Sub Command1_Click() Dim c% c = a(2)End Sub单击两次命令按钮,第二次显示的结果是( )。
