(Package Inheritance Hierarchy) Package-delivery services, such as FedEx®, DHL® and UPS®, offer a number of different shipping options, each with specific costs associated. Create an inheritance hierarchy to represent various types of packages. UsePackage as the base class of the hierarchy, then include classes TwoDayPackage and OvernightPackage that derive fromPackage. Base class Package should include the name, address, city, state and zip code for the package's sender and recipient, and instance variables that store the weight (in ounces) and cost per ounce to ship the package. Package's constructor should initialize these private instance variables with public properties. Ensure that the weight and cost per ounce contain positive values. Package should provide a public method CalculateCost that returns a decimal indicating the cost associated with shipping the package. Package's CalculateCost method should determine the cost by multiplying the weight by the cost per ounce. Derived class TwoDayPackage should inherit the functionality of base class Package, but also include an instance variable that represents a flat fee the shipping company charges for two-day delivery service. TwoDayPackage's constructor should receive a value to initialize this instance variable. TwoDayPackage should redefine method CalculateCost so that it computes the shipping cost by adding the flat fee to the weight-based cost calculated by base class Package's CalculateCost method. ClassOvernightPackage should inherit directly from class Package and contain an instance variable representing an additional fee per ounce charged for overnight delivery service. OvernightPackage should redefine method CalculateCost so that it adds the additional fee per ounce to the standard cost per ounce before calculating the shipping cost. Write a test application that creates objects of each type of Package and tests method CalculateCost.
