Decimal to Binary Conversion Algorithm

Step 1: Divide the number by 2 through % (modulus operator) and store the remainder in array

Step 2: Divide the number by 2 through / (division operator)

Step 3: Repeat the step 2 until the number is greater than zero

Let us see the C# example to convert decimal to binary.

Program Code

using System;  
  public class ConversionExample  
   {  
     public static void Main(string[] args)  
      {  
       int  n, i;       
       int[] a = new int[10];     
       Console.Write("Enter the number to convert: ");    
       n= int.Parse(Console.ReadLine());     
       for(i=0; n>0; i++)      
        {      
         a[i]=n%2;      
         n= n/2;    
        }      
       Console.Write("Binary of the given number= ");      
       for(i=i-1 ;i>=0 ;i--)      
       {      
        Console.Write(a[i]);      
       }                 
      }  
  }

Output

Enter the number to convert:10
Binary of the given number= 1010

How to learn from this program

First read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.

Practice suggestion

After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
