问题编写如下程序：
Private Sub Form_Click()
Dim a(5) As Integer, b(3) As Integer
Dim k As Integer
k = 1
For i = 1 To 5
      a(i) = i
Next i
For i = 1 To 3
      b(i) = 2 * a(i)
Next i
For i = 1 To 3
      k = k + b(i) * 2
Next i
Print k
End Sub
运行程序，单击窗体，输出结果是

选项 A、31
B、32
C、25
D、30

答案C

解析通过For循环，对整型数组a和b分别赋值，a=[1，2，3，4，5]，b=[2，4，6]，k是在原值基础上再加b每个元素值得两倍，故k=1+2*2+4*2+6*2=25，故选C项。
