Question 1
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. Use Package as the base class of the hierarchy, then
include classes TwoDayPackage and OvernightPackage that derive from Package. Base
class Package should include data members representing the name, address, city, state and
ZIP code for both the sender and the recipient of the package, in addition to data members that
store the weight (in ounces) and cost per ounce to ship the package. Package’s constructor
should initialize these data members. Ensure that the weight and cost per ounce contain
positive values. Package should provide a public member function calculateCost that
returns a double indicating the cost associated with shipping the package. Package’s
calculateCost function 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 a data member that represents a flat fee that the shipping company charges for
two-day-delivery service. TwoDayPackage’s constructor should receive a value to initialize this
data member. TwoDayPackage should redefine member function 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 function. Class OvernightPackage should inherit
directly from class Package and contain an additional data member representing an additional
fee per ounce charged for overnight-delivery service. OvernightPackage should redefine
member function calculateCost so that it adds the additional fee per ounce to the standard
cost per ounce before calculating the shipping cost.Write a test program that creates objects of
each type of Package and tests member function calculateCost.

Question 2
Use the Package inheritance hierarchy created in Question 1 to create a program that displays
the address information and calculates the shipping costs for several Packages. The program
should contain a vector of Package pointers to objects of classes TwoDayPackage and
OvernightPackage. Loop through the vector to process the Packages polymorphically.
For each Package, invoke get functions to obtain the address information of the sender and the
recipient, then print the two addresses as they would appear on mailing labels. Also, call each
Package’s calculateCost member function and print the result. Keep track of the total
shipping cost for all Packages in the vector, and display this total when the loop terminates.

So do you have a real question or are you just another lazy leech who wants other people to do his homework?

>having too many errors....
I get two compilation errors, both having to do with trying to use the return value of a member function that returns void. Take a look at your CalCost member functions and change the return type to double.

You'll also have linker errors as you've neglected to define the member functions you declare.

Disclaimer: This code should be used as a learning tool. If you decide to use it improperly (cheating), then that's something you'll have to live with. It isn't up to me to decide what's fair and what isn't. If you don't like it, no one is going to force you to use it. If you feel that my posting this enables cheaters, then I urge you to stop worrying so much about how other people spend their time, and worry a little more about getting a life. Happy coding.
