VB中递归的用法:

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...

Private Sub Command1_Click() Dim a As Integer, b As Integer a = Text1 b = Text2 Text3 = gcd(a, b) End Sub Function gcd(ByVal a As Integer, ByVal b As Integer) As Integer If a Mod b = 0 Then gcd = b Else gcd = gcd(b, a Mod b) En...

最后一行打印的并不是最后一次a的值(1),而是第一次递归调用时a的值(2)。

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...

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 Form_Click() Print fact(4)End SubPublic Function fact(n As Integer) As Long If n = 1 Then fact = 1 Else fact = n * fact(n - 1) End If 'Print fact;End Function

第1题: 添加一个按钮,完整代码如下: Option Explicit Private Sub Command1_Click() Print Y(20) End Sub Private Function Y(ByVal n As Integer) As Single If n = 1 Then Y = 2 / 1 Else Y = (n + 1) / n + Y(n - 1) End If End Function ...

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

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...
