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;  // Importing necessary namespace

public class Exercise53  // Declaration of the Exercise53 class
{  
    public static void Main()  // Main method, entry point of the program
    {       
        int n1, n, p = 1;  // Declaration of variables
        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());  // Taking user input for a binary number	
        n1 = n;  // Storing the original binary number for display at the end

        // Converting the binary number to its decimal equivalent
        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++;
        }

        // Converting the decimal equivalent to its octal representation
        i = 1;
        for (j = dec; j > 0; j = j / 8)
        {
            ocno = ocno + (j % 8) * i;
            i = i * 10;
            n = n / 8;
        }

        // Displaying the original binary number and its equivalent octal number
        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
