VB中的递归法是怎样的

Private Sub Form_load() Dim i As Long,n as integer n=int(val(inputbox("输入Fibonacci数列的项数"))) For i = 1 To n Print Fibonacci(i) Next End Sub Private Function Fibonacci(n As Long)As Long If n = 1 Then Fibonacci = 1 ElseIf n...

Private Sub Form_load() Dim i As Long,n as integer n=int(val(inputbox("输入Fibonacci数列的项数"))) For i = 1 To n Print Fibonacci(i) Next End Sub Private Function Fibonacci(n As Long)As Long If n = 1 Then Fibonacci = 1 ElseIf n...

Function Factorial(n As Integer) As DoubleIf Factorial = 0 Then Factorial = 1If n > 1 Then Factorial = n * Factorial(n - 1)End FunctionPrivate Sub Form_Click() '点击窗体运行MsgBox "阶乘计算结果为 " & Factorial(Val(InputBox("请...

Private Sub Command1_Click() n = CInt(InputBox("请要求几的阶乘?")) MsgBox (n & "!=" & fact(n)) End Sub Function fact(n) s = 1 For i = 2 To n s = s * i Next i fact = s End Function

Public Function s(n As Integer) As Long If n = 1 Then s = 1 Else s=n * s(n-1) End If End Function Private Sub Form_Click() Print “s(5)=”;s(5) End Sub

非常简单: Function Factorial(ByVal n As Integer) As Long If n < 2 Then Factorial = 1 Else Factorial = n * f(n - 1) End IfEnd Function

Function fun(n As Integer) As Long If n = 0 Or n = 1 Then fun = 1 Else fun = n * fun(n - 1) End IfEnd FunctionSub test() MsgBox fun(5)End Sub理解递归,不能从像一般函数那样用过程的方式来理解,而要用“功能”的方式去理解,如果你有面...

Form1上放一个文本框Text1, 一个按钮Command1。 在框中输入某个数字,例如10,代码会将列出f(1)至f(10)的值。 如果你只需要特定的第n项,比如第8项,就直接调用DiGui(8)即可。 代码: Private Sub Command1_Click() Dim n As Long n = CInt(Tex...

Private Sub Command1_Click() Label3.Caption = "转换后的" & Val(Text2.Text) & "进制数为" + Transformation(Val(Text1.Text), Val(Text2.Text))End SubPrivate Function Transformation(ByVal n As Long, ByVal k As Integer) As String If ...

Text1.Text = f(Val(Text1.Text)) 表示的意思是先把传入的文本字段Text1.Text 利用val 函数转化为int数值。然后调用自定义的递归函数 f (n as Integer) ,并把刚转化为int的数值作为参数传入其中,经过递归函数运算得到的结果作为返回值并赋值给...
