执行下列语句后变量i的值是( )。For i=1 to 5i=i+1Next i A: 6 B: 5 C: 7 D: 10

执行下列语句后变量i的值是( )。For i=1 to 3i=i+1Next i A: 3 B: 4 C: 5 D: 6

"下列程序段中，语句i=i+1执行了（）次。For i=1 to 5 i=i+1Next i A: 2 B: 3 C: 4 D: 5

写输出下面程序的运行结果_ _。 Dim a() As Integer Private Sub Command1_Click() ReDim a(1 To 5) For i = 1 To 5 a(i) = i Next i ReDim a(1 To 10) For i = 6 To 10 a(i) = 2 * i Next i For i = 1 To 10 Print a(i); Next i End Sub

下列程序段的执行结果为【 】。 K=0 For J=1 To2 For I = 1 To 3 K=I+1 Next I For I=1 To7 K=K+I Next I Next J Print K

以下程序的运行结果是 Sub s1(b() As Integer) For i = 1 To 4 b(i) = 2 * i Next i End Sub Private Sub Command1_Click() Dim a(1 To 4) As Integer For i = 1 To 4 a(i) = i + 5 Next i s1 a() For i = 1 To 4 Print a(i) Next i End Sub

下列程序: Option Base 1 Private Sub Form_Click() Dim a(5，5) For i ＝ 1 To 5 For j ＝ 1 To 5 k ＝ k ＋ 1 a (i，j)＝ k Next j Next i For i ＝ 1 To 5 s ＝ s ＋ a (i，i) Next i Print s End Sub 运行时的输出结果是( )。

假设有以下程序段： For i=1 to 3 For j=5 to 1 Step -1 Next j Next i Print i,j 则i、j的值分别是

以下程序，执行循环体的次数是。 For i=1 To 3 For j=5 To 1 step -1 print i+j Next j Next i

下面的程序段执行后共循环了 次 For i = 1 To 2 For j = 5 To 1 Step -1 Print i*j Next j Next i
