Part A:

Create a makefile. Source file names are Package.h$,$ Package.cpp$,$ TwoDayPackage.h$,$ TwoDayPackage.cpp$,$

and Labll.cpp$.$ The executable file name should be Labl$1.$

Part B:

Using the UML Class Diagrams below as your guide, write the Package and TwoDayPackage class definitions.

$($the $h$ files$).$ Class Package is the base class. TwoDayPackage is the derived class $($use public inheritance$).$

Inheritance in UML diagrams is indicated by a solid line with arrowhead pointing at the base class.

Double check your prototypes in Package.h to make sure they match the UML. Then create Package.cpp and

write the function definitions.

Double check the prototypes in TwoDayPackage.h to make sure they match the UML. Then create

TwoDayPackage.cpp and write the function definitions.

Part C:

Write a test program called Labll.cpp that will instantiate several Package and TwoDayPackage objects.

Thoroughly test all of the member functions of these classes.
