Hello. I am new to this. Thank you for a website like this where people can help! This is a Qt assignment. I already started with the question but I always get to a point then I don’t know anymore.

Given below is a UML class diagram that models three types of references; generic references, journal
articles and conference papers.

A reference can be authored by many authors. In Reference, the authors are represented by the data
member authors of type QStringList where each author is stored as a QString. Besides a list of
authors, the Reference class has data members to store the title of the reference, year of publication, a
reference ID and a reference type. The reference types for a generic reference, a journal article and a
conference paper are “Generic”, “Journal” and “Conference” respectively.

The subclasses of Reference have additional data members and functions. A journal article also stores
the name of the journal, volume and number. A conference paper also stores the conference name and
the month in which the conference was held. Most of the functions in the Reference class hierarchy are
self-explanatory.

There are numerous referencing styles used by scientific communities for generating entries in a
bibliography. One such style is APA. The function toAPAStyle() in the Reference class hierarchy is
meant to return a bibliographic entry in a style more or less similar to APA. Given below are three
examples of bibliographic entries to be returned by toAPAStyle() in the Reference,
JournalArticle and ConferencePaper classes.

In general, a toString() function returns the string equivalent of the state of an object. The state of an
object refers to the values of its data members at a given time. In the Reference class hierarchy,
implement toString() so that the values of the data members are appropriately labeled. An example
of a labeled generic reference is given below:

Given below are the details of a container class named ReferenceList that manages a list of
References. The Reference class in the diagram is the same as the Reference class in the UML
class diagram above.

The functions of the ReferenceList class should do the following:
? The destructor should delete all the Reference objects.
? addReference() adds an object pointed to by a Reference pointer, provided a reference with the
same reference ID does not exist in the list. The function returns true or false to indicate whether
the reference was successfully added.
? generateReferences() returns the string equivalent of all references for the reference IDs passed
to the function. The bool parameter full indicates how the requested references should be
included. When full is true, it should return the complete labeled string representation of
references and when it is false, it should return the APA style string representation of references.
? getIDsByAuthor() returns all the reference IDs of the references authored by a given author.
? getIDsByConference() returns all the reference IDs of the references presented at a conference.
? getIDsByJournalName() returns all the reference IDs of the references published in a specific
journal.
? findByID() checks whether a reference with the given ID exists in the list of references. If it exists,
the function returns a pointer to that Reference object. If it does not exist, the function returns a null
pointer. Take note to invoke this function in other functions of ReferenceList when appropriate.
Test all these classes by creating at least two objects of every concrete class in the Reference
hierarchy and by adding them to a ReferenceList object. Also try adding a Reference object that is
already in the list to demonstrate that each reference in the list has a unique reference ID. Then test
getIDsByAuthor(), getIDsByConference(), getIDsbyJournalName() with appropriate
arguments. The reference IDs returned by these three functions should be used to test
generateReferences(). The QString returned by generateReferences() should be displayed
on the console. You should also demonstrate the difference in the string representation of references by
generateReferences() when the bool parameter full is true or false.

You need to develop a console application and not a GUI app.
