This Code Calls Math Operations using Delegates

C#
 using System;
public class MathOperations
{
    public static double Multiply(double value)
    {
        return value * 2;
    }
 
    public static double Square(double value)
    {
        return value * value;
    }
}
 
 
delegate double DoubleOp(double x);
 
class Application
{
    static void Main()
    {
        DoubleOp[] operations =
            {
               MathOperations.Multiply,
               MathOperations.Square
            };
 
        for (int i = 0; i < operations.Length; i  )
        {
            Console.WriteLine("Operation[{0}]:", i);
            ProcessAndDisplayNumber(operations[i], 5.0);
            ProcessAndDisplayNumber(operations[i], 13.55);
            ProcessAndDisplayNumber(operations[i], 1.732);
            Console.WriteLine();
        }
        Console.ReadLine();
    }
 
    static void ProcessAndDisplayNumber(DoubleOp action, double value)
    {
        double result = action(value);
        Console.WriteLine(
           "Value : {0}  Result : {1}", value, result);
    }
} 

/*
Here is the output of the C# Program: Operation[0]: Value : 5 Result : 10 Value : 13.55 Result : 27.1 Value : 1.732 Result : 3.464 Operation[1]: Value : 5 Result : 25 Value : 13.55 Result : 183.6025 Value : 1.732 Result : 2.999824
