将二进制数转换为八进制数... [英] Convert Binary number to octal...

问题描述

我有一个接受二进制数的代码。当我运行它并给出二进制数1011时，它给出521而不是13.所以，如何将二进制转换为八进制。以下是代码

-------------------------------------- -------------

 私有  Sub  Button2_Click（发件人作为系统。对象，e  As  System.EventArgs）句柄 Button2.Click 
  Dim  n，tmp，rm 作为 长 
  Dim  cnt  As  整数 =  0  
  Dim  sum  As   Integer  =  0  
n = Val（txtnum.Text）
 tmp = n 
 rm =  0  
 su m =  0  
 cnt =  0  
 而 tmp>  0  
 rm = tmp  Mod   10  
 tmp \ =  10  
 sum = sum +（rm *（Pow（ 8） ，cnt）））
 cnt = cnt +  1  
 结束 虽然 
 txtoct.Text = sum.ToString（）
 结束  Sub  

解决方案

有很多方法可以做到这一点，但我分两个阶段进行：

1）编写一个方法将二进制字符串转换为整数。

2）编写一个将整数转换为八进制的方法。



现在，有.NET方法可以做到这两点，但我认为这是你的功课？所以你必须自己编写它们？



首先编写占位符方法，使用.NET框架方法检查代码：

Convert.ToInt32 [ ^ ]将二进制字符串处理为整数

Convert.ToString [ ^ ]将转换指定基数中字符串的整数。



然后，您可以为每种方法编写自己的代码，并确保获得相同的结果！

 Convert.ToString（Convert.ToInt32（10011，2），8）
 

I Have a code that accepts binary number. When I run it and give binary number 1011 it gives 521 instead of 13. So, how to convert binary to octal. Below is the code
---------------------------------------------------

Private Sub Button2_Click(sender As System.Object, e As System.EventArgs) Handles Button2.Click
       Dim n, tmp, rm As Long
       Dim cnt As Integer = 0
       Dim sum As Integer = 0
       n = Val(txtnum.Text)
       tmp = n
       rm = 0
       sum = 0
       cnt = 0
       While tmp > 0
           rm = tmp Mod 10
           tmp \= 10
           sum = sum + (rm * (Pow(8, cnt)))
           cnt = cnt + 1
       End While
       txtoct.Text = sum.ToString()
   End Sub

解决方案

There are a huge number of ways to do this, but I'd do it in two stages:
1) Write a method to convert a binary string to an integer.
2) Write a method to convert an integer to Octal.

Now, there are .NET methods that will do both of those, but I assume this is your homework? So you have to write them yourself?

So start by writing "placeholder" methods which use the .NET framework methods to check your code:
Convert.ToInt32[^] will handle binary string to integer
Convert.ToString[^] will convert an integer to a string in the specified base.

Then, you can just write your own code for each method and make sure you get the same results!

Convert.ToString(Convert.ToInt32("10011", 2),8)
