Recursive-function

Aim:

To write a C# program to reverse a number using recursive function.

Algorithm:

Step1: Create a function for reversing.

Step2: Get the number from the user.

Step3: In the function find reminder of the number and multiply it by 10 and add the reverse number.

Step4: Recusively call this function to get the reversed number.

Step5: print the reversed number.

            {
                m = n % 10;
                reverse = reverse * 10 + m;
                n /= 10;
                return J(n);
            }
            return reverse;
        }
        static void Main(string[] args)
        {
            int num;
            Console.WriteLine("Enter a number: ");
            num = Convert.ToInt32(Console.ReadLine());
            Console.WriteLine("Reverse of the number: ");
            Console.WriteLine(J(num));
        }
    }
}

Output:

Result:

Thus the C# program to reverse a number using recursive function is executed successfully.
