Understanding Delegates

    class Program
    {
        public delegate int Calculate(int x, int y);

        public static int Add(int x, int y)
        {
            return x + y;
        }

        public static int Multiply(int x, int y)
        {

        {
            Calculate calc = Add;
            Console.WriteLine(calc(3, 4));

            calc = Multiply;
            Console.WriteLine(calc(3, 4));

            Console.ReadKey();
        }
