Visual Presentation:

Sample Solution:

C# Sharp Code:

using System;  // Importing necessary namespace

public class Exercise50  // Declaration of the Exercise50 class
{  
    public static void Main()  // Main method, entry point of the program
    {
        // Declaration of variables
        int n, i, j, octalNumber = 0, dn;

        // Displaying information about converting decimal to octal
        Console.Write("\n\n");
        Console.Write("Convert decimal number to octal without using array:\n");
        Console.Write("------------------------------------------------------");
        Console.Write("\n\n");	

        // Prompting the user to enter a decimal number
        Console.Write("Enter a number to convert : ");
        n = Convert.ToInt32(Console.ReadLine());  // Reading the decimal number

        dn = n;  // Storing the original number for display
        i = 1;   // Initializing a multiplier for place values in octal system

        // Loop to convert decimal to octal without using an array
        for (j = n; j > 0; j = j / 8)
        {
            // Calculating the octal number digit by digit
            octalNumber = octalNumber + (j % 8) * i;
            i = i * 10;  // Incrementing the place value multiplier for next digit
            n = n / 8;   // Updating the original number
        }

        // Displaying the converted octal number
        Console.Write("\nThe Octal of {0} is {1}.\n\n", dn, octalNumber);
    }
}

Sample Output:

Convert decimal number to octal without using array:                                                        
------------------------------------------------------                                                      
Enter a number to convert : 6                                                                               
The Octal of 6 is 6.
