CPS $271$ Machine Problem $2-$ Inheritance

Objectives: implement a class and composition.

To use the dynamic allocation to store objects and their data.

To use default constructor and overload constructor with full parameters.

To use setter functions and getter functions.

To use constant and static members.

To use Inheritance

To use override functions

Package$-$delivery services, such as DHL$,$ offer a number of different shipping options, each has specific cost.

$1.$ Write the header file and the implementation file for each of the following classes.

A class called PACKAGE as the base class: $(10$ points$)$

Data members of PACKAGE:

$1.$ name $2.$ address $3.$ city $4.$ state $5.$ zipcode

$($for both sender and receiver$)$

$6.$ weight $($in ounces$)7.$ cost$/$ounce

Default constructor; initialize the data memebrs.

Constructor$($s$)$ with parameters set the data members according to the parameters.

Setter Functions to set the data members according to the parameters.

Getter Functions to return the data members.

Function to calculate the cost of the package

Function to output the data members in the form:

Name

Address

city, state zipcode

cost

A class called TwoDayPackage derived from PACKAGE: $(10$ points$)$

Data member to store:

$1.$ Flat fee for the Two Days Package.

Default constructor initializes the fee to $$10\mathrm{.}99$;

Constructor with parameters.

Setter Function to set the data member

Getter Function to return the data member

An override Function calculate the cost by adding the fee to the cost that was calculated in the base class.

A class called OvernightPackage derived from PACKAGE: $(10$ points$)$

Data members to store:

$1.$ Fee per ounce

Default constructor initializes the additional fee to $$0\mathrm{.}50$ per ounce;

Constructor with parameters.

Setter Function to set the data member

Getter Function to return the data member

An override Function calculate the cost by adding the additional fee per ounce to the standard cost before calculating the shipping cost that was calculated in the base class.

$2.$ Write a main program $($Dem$)$ to test the reliability and validity of the above classes by showing the results of most of the functions you built. $(20$ ppints$)$

Your program should create two objects $($TwoDay and the Overnight$)$

Your program$/$header files should be submitted in addition to the output of the calculate cost for each object.
