How to create a method that return the average for 5 doubles !!

Question

Vulpes · Answer

Try this. As you may not have learned LINQ yet, I've used 'traditional' code to work out the average: using System; class Program { static void Main() { double[] numbers = new double[5]; Console.WriteLine("Please enter 5 doubles
"); for(int i = 0; i { while(true) { Console.Write("Double {0} : ", i + 1); bool isValid = double.TryParse(Console.ReadLine(), out numbers[i]); if (isValid) break; Console.WriteLine("Not a valid double, please re-enter"); } } Console.WriteLine("
The average of these numbers is {0}", Average(numbers)); Console.ReadKey(); } static double Average(double[] numbers) { if (numbers == null || numbers.Length == 0) throw new ArgumentException("Array is null or empty"); double total = 0; foreach(double number in numbers) total += number; return total/numbers.Length; } }

you can easily use LINQ to implement it. like below ? class Program { static void Main(string[] args) { var values = new double[] { 1,2,3,4,5 }; Console.WriteLine(Average(values)); Console.Read(); } static double Average(double[] values) { if (values == null || values.Length == 0) throw new ArgumentException("Parameter is null or empty"); return values.Average(); } }
