Program that adds input numbers until user inputs "0"

Question

Hello again, C# corner users!
I need to make a program that will add numbers that user inputs, until user inputs 0.

It should look like this at the end:

----------------------------------------------------
[Summation of Real numbers]
Write 0 to Finish

Write an amount to sum or 0 to finish: 50
Write an amount to sum or 0 to finish: 40
Write an amount to sum or 0 to finish: 10.5
Write an amount to sum or 0 to finish: 0

The sum is : 100.5


----------------------------------------------------

Below are the outlines that I got so far:

Thanks for your help guys!




public class FloatNumbersWhileAdd

    {

        private double sum;

        public void Start()

        {

            WriteProgramInfo();

            ReadInputAndSumNumbers();

            ShowResults();

        }

        private void WriteProgramInfo()

        {

            // Coding part here

        }

        private void ReadInputAndSumNumbers()

        {

            bool done = false;

            while (!done)

            {

                // Coding part here

            }

        }

        

        private double ReadInput()

        {

            Console.Write("Write an amount to sum or zero to finish: ");

            double num = double.Parse(Console.ReadLine());

            return num;

        }

        private void ShowResults()

        {

            // Coding part here

        }

    }

}
