Exercise 2
    Is the following code easily maintainable? How would you improve it?
    public class Product

    {
        ...
        public decimal Price()
        {
            if (UOM.Equals("grams"))
            return Quantity * 6m / 1000;
            if (UOM.Equals("bottle"))
            return Quantity * 3m;
            if (UOM.Equals("bag"))
        {
            var total += Quantity * .2m;

            Página 2/3

            var setsOfFour = Quantity / 4;
            total -= setsOfFour * .15m; //discount on groups of 4 items
            return total;
        }
            return 0m;
        }
    }

Exercise 3
    How would you improve the maintainability of the following code?
    public class Employee
    {
        private int _type;
        static final int ENGINEER = 0;
        static final int SALESMAN = 1;
        static final int MANAGER = 2;
        public double MonthlySalary {get; set;}
        public double Commission {get; set;}
        public double Bonus {get; set;}
        public Employee (int type) { _type = type; }
        public int GetPaymentAmount()
        {
            switch (_type) {
                default:
                case 0:
                return MonthlySalary;
                case 1:
                return MonthlySalary + Commission;
                case 2:
                return MonthlySalary + Bonus;
            }
        }
    }
