C#: Decimal to Binary

Last update on August 20 2025 12:40:01 (UTC/GMT +8 hours)

Write a C# Sharp program that takes a decimal number as input and displays its equivalent in binary form.

Sample Solution:-

C# Sharp Code:

using System;

public class Exercise10
{
    public static void Main()
    {
        // Declare variables to store two numbers and a boolean to determine if both are even
        int n1, n2;
        bool bothEven;

        // Input the first number
        Console.Write("Input First number: ");
        n1 = Convert.ToInt32(Console.ReadLine());

        // Input the second number
        Console.Write("Input Second number: ");
        n2 = Convert.ToInt32(Console.ReadLine());

        // Check if both numbers are even using logical operators
        bothEven = ((n1 % 2 == 0) && (n2 % 2 == 0)) ? true : false;

        // Output the result based on whether both numbers are even or not
        Console.WriteLine(bothEven ? "There're numbers both even" : "There's a number odd");
    }
}

Sample Output:

Input a Number : 65                                                                                           
Binary: 1000001
