# 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
```
