C#: Convert binary number to octal

C# Sharp For Loop: Exercise-53 with Solution

Write a program in C# Sharp to convert a binary number to octal.

Sample Solution:-

C# Sharp Code:

using System;  
public class Exercise53
{  
    public static void Main()
{       int n1, n,p=1;
	    int dec=0,i=1,j,d;
        int ocno=0;
		
	Console.Write("\n\n");
    Console.Write("Convert binary number into octal:\n");
    Console.Write("-----------------------------------");
    Console.Write("\n\n");		

	Console.Write("Input a binary number :");
    n = Convert.ToInt32(Console.ReadLine());	
	n1=n;
	for (j=n;j>0;j=j/10)
	{  
          d = j % 10;
            if(i==1)
                  p=p*1;
            else
                 p=p*2;

	   dec=dec+(d*p);
	   i++;
	}
 
/*--------------------------------------------*/
     i=1;

      for(j=dec;j>0;j=j/8)
       {
        ocno=ocno+(j % 8)*i;
        i=i*10;
        n=n/8;
       }
   
        Console.Write("\nThe Binary Number : {0}\nThe equivalent Octal  Number : {1} \n\n",n1,ocno);
}
}

Sample Output:

Convert binary number into octal:                                                                           
-----------------------------------                                                                            
Input a binary number :110101                                                                                  
The Binary Number : 110101                                                                                  
The equivalent Octal  Number : 65
