尼克斯彻定理:任何一个大于等1的整数的立方等于一串连续奇数之和,如:13=1,23=3+5,33=7+9+11。编写一个VB程序验证尼克斯彻定理,程序运行时,在文本框Text1中输入一个于等于1的整数,单击“验证”按钮Command1,在文本框Text2中显示验证结果,运行界面如图所示。
实现上述功能的VB代码如下,请完善代码:
Private Sub Command1_Click()
Dim n As Integer, i As Integer, t As Integer, sum As Long, s As String
n=Val(Text1.Text)
For i=1 To n^3 step 2 '变量i表示连续奇数的首个整数
sum=0:t=i:flag=False
Do While sum<n^3 And flag= False
sum= {#blank#}1{#/blank#}
t=t+2
If {#blank#}2{#/blank#} Then flag=True
Loop
If flag=True Then Exit For
Next i
s=Str(n)+ "^"+Str(3)+ "="
Do While sum>0
{#blank#}3{#/blank#}
If sum= 0 Then
s=s+Str(i)
Else
s=s+Srt(i)+ "+"
End If
i=i+2
Loop
Text2.Text=s
End Sub
