Question

Please submit only one zip file .Your zip file should contain the following files:

• ItemListClass.h
• ItemListMethods.cpp
• ItemListTests.h
• ItemListTests.cpp
• makefile
• numbers.txt

How is it possible to turn in 2 cpp files? Does that mean I am gonna have 2 different projects and combine them into one? I understand classes, but I am unsure how they could be all used in a zip file.

Note: I am not looking for code; I am looking for understanding. Maybe someone has done something similar? this is a grocery list with integers instead of items.

Answer 1

• ItemListClass.h
• ItemListMethods.cpp
• ItemListTests.h
• ItemListTests.cpp
• makefile
• numbers.txt

This implies that ItemListClass.h provides the caller-visible interface for your ItemList, that the out-of-line implementation for the member functions of ItemList go in ItemListMethods.cpp, and that a test program (presumably with a main() function in ItemListTests.cpp) will exercise the ItemList functionality. I can see no particular reason to think that ItemListTests.h is useful… whatever ItemListTests could credibly contain is unlikely to be of use to any code other than ItemListTests.cpp, and if it was then it should really be moved into a “TestSupport.h” header or similar. But, the implication is that ItemListMethods.cpp should include ItemLists.h, and ItemListTests.cpp should include ItemListTests.h. numbers.txt is presumably input data that your ItemListTests.cpp will read through to populate an ItemList object during testing. The makefile should do something vaguely like:

ItemListTest: <tab> ItemList.o ItemListTest.h ItemListTest.cpp
<tab>g++ -g -o ItemListTest ItemList.o ItemListTest.cpp

ItemList.o: <tab> ItemList.h ItemList.cpp
<tab>g++ -g -c ItemList.cpp

You can then type “make” in the same directory to build an executable ItemListTest.
