C# Program To Convert Decimal To Binary

We have the ability to transform any decimal numeral (base-10 (0 through 9)) into a binary numeral (base-2 (0 or 1)) using a C# program.

Decimal Number

A decimal number is classified as a base 10 number due to its range from 0 to 9, encompassing a total of 10 digits. Any sequence of these digits, like 223, 585, 192, 0, or 7, constitutes a decimal number.

Binary Number

A binary number operates on a base 2 system, encompassing only the digits 0 and 1. Any sequence containing a combination of these two digits forms a binary number, like 1001, 101, 11111, or 101010.

Let's examine some binary representations for decimal numbers.

Decimal Binary
1 0
2 10
3 11
4 100
5 101
6 110
7 111
8 1000
9 1001
10 1010

Decimal to Binary Conversion Algorithm

Step 1: Divide the number by 2 using the % (modulus operator) and save the remainder in an array.

Step 2: Divide the value by 2 using the / (division operator).

Repeat the second step iteratively until the numerical value exceeds zero.

Let's explore the C# demonstration on converting a decimal number to binary.

Example

Example

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:

Output

Enter the number to convert:10

Binary of the given number= 1010
