C# Sharp Recursion: Exercise-13 with Solution
Write a program in C# Sharp to convert a decimal number to binary using recursion.
Pictorial Presentation:

Sample Solution:
C# Sharp Code:
using System;
class RecExercise13
{
public static void Main(string[] args)
{
int num;
DecToBinClass pg = new DecToBinClass();
Console.WriteLine("\n\n Recursion : Convert a decimal number to binary :");
Console.WriteLine("------------------------------------------------------");
Console.Write(" Input a decimal number : ");
num = int.Parse(Console.ReadLine());
Console.Write(" The binary equivalent of {0} is : ", num);
pg.deciToBinary (num);
Console.ReadLine();
Console.Write("\n");
}
}
public class DecToBinClass
{
public int deciToBinary(int num)
{
int bin;
if (num != 0)
{
bin = (num % 2) + 10 * deciToBinary(num / 2);
Console.Write(bin);
return 0;
}
else
{
return 0;
}
}
}
Sample Output:
Recursion : Convert a decimal number to binary : ------------------------------------------------------ Input a decimal number : 65 The binary equivalent of 65 is : 1000001
