Loop or Recursive method? Which one is better to use?

Question

I want to ask user to enter a value less than 10. I am using the following code. Which one is better to use? Loop or Recursive method. Someone said me using Recursive function method may cause Memory Leakage. Is it true?

 class Program
    {
        static void Main(string[] args)
        {
            int x;
            do
            {
                Console.WriteLine("Please Enther a value less than 10.");
                x = int.Parse(Console.ReadLine());
            } while (x > 10);

             //Uncomment the bellow method and comment previous to test the Recursive method
             //Value();
        }
        static string Value()
        {
            Console.WriteLine("Please Enther a value less than 10.");
            return int.Parse(Console.ReadLine()) > 9 ? Value() : "";
        }
    }

Answer 1

It would probably be a long time before recursion became an issue in this example.

Recursive methods run the risk of causing stack overflow exceptions if they keep running for a long time without completing. This is because each method call results in data being stored on the stack (which has very limited space) - more info here:

In your case unless they enter a number greater than or equal to 10 loads of times or you have very little memory it should be fine.

Generally it's better to use loops than recursion as they are simpler to understand. Recursion is a useful tool for achieving good performance in certain scenarios but generally loops should be preferred.
