Composition



Class Heiarchy




You are developing a class hierarchy for this project. An Abstract Base Class (ABC), ‘Smalltalk’ defines the hierarchy behavior. Most of your work in this class structure will take place in Smalltalk.




Classes derived from Smalltalk must implement populatePhrases(). A function that initializes the baseclass vector with phrases that are unique to that class type. For instance, Smalltalk_American will populate its internal vector of strings with the american phrases found in constants.h.




Additionally you are given a complete watch object. You may give or take a watch from any instance of Smalltalk_American, ST_American_DonutEnthusiest or Smalltalk_Brit. Note that watches cannot be created out of thin air, if you give one to an instance you no longer have that watch, the instance does. See Smalltalk.h for further guidance.




Please also provide a function (as specifies in Functions.h and outlined in Functions.cpp) that generates a vector of unique pointers to objects derived from smalltalk. Please pay attention to the hints I’ve left you in the implementation.




Please compile both projects using the C++11 language standard.




Library

I would like you to fill in noted content in the following project structure.










































































































Fill in this file










And create these 4 files
















Note the file ‘output’ under CONSOLE_OUTPUT_OF_SUCCESSFUL… It has a listing of what a successful run should look like.





























































All classes inherit publicly. The class hierarchy is as follows;
































































I have given you the header files and some of the implementation.




Testing

Please see the test application with the following name and file structure:
















327_Proj_ST.cpp is a complete tester for the classes and functions you develop in the lib. This application should link statically to the above library. The projects as they appear in the eclipse workspace.




























Submission:

Only the following 5 files. Please do not zip them together, or embed them in a




directory structure. Just the 5 files.

Functions.cpp

Smalltalk_American.cpp




Smalltalk_Brit.cpp

Smalltalk.cpp

ST_American_DonutEnthusiest.cpp

Grading:




For each concrete class remember to push as much common functionality as possible into base classes! This cuts down on repetitive code in derived classes.




5% Submission instructions followed




25% getPeople populated correctly with unique pointers

25% populatePhrases implemented correctly




saySomething cycles correctly through available phrases

25% takeWatch, giveWatch, getTime correct

10% valgrind returns no errors




10% Code style (refactor repetitive code into functions, no magic numbers, no large blocks of empty space, no large chunks of commented out code, pushing as much functionality in base class as possible, appropriate comments, your name at the top of each file, etc.)
