The answer for coding problem should be following: public class Flower { public int price; public int quantity; public virtual int getCost() { return price * quantity; } } public class Rose:Flower { } public class Lily:Flower { } class Program { static void Main(string[] args) { int totalCost = 0; var flowerObj = new List() { new Rose(){price=10,quantity=5}, new Lily(){price=20,quantity=10}, }; foreach(var o in flowerObj) { totalCost += o.getCost(); } Console.WriteLine(totalCost); } }
