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[] { 12345 }; 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(); } }
