Consider the following class diagram, detailed description of the diagram is given in the table.

Class Name	Attribute Name	Attribute Data Type	Behavior (Functions)
Virtual Ballot Paper	NoOfsigns	Integer	-Default Constructor() -DisplaySign() -Destructor()
NameOfVotingCategory	Character String
Candidate	Name	Character String	-Default Constructor() -Parameterized constructor (...) -Destructor()
Address	Character String
CandidateType	Character String
NoVotes	Integer
Sign	Name	Character String	-Select() -Destructor()
Constituency	NoOfCandidates	Integer	-Default Constructor() -Parameterized constructor (...) -GetConstituencyNo() -Destructor()
NoOfVoters	Integer
ConstituencyNo	Integer
Result			-CountVotes() -AnnounceResult() -Destructor()

You are required to map (implement) this class diagram in C++.
Make sure that your [COLOR=#0000FF !important]solution[/COLOR] must contain only classes' definitions given in the diagram, definitions of all attributes and proper declaration and definitions of member functions including constructors that are given in the above table.

Details of Member functions:

DisplaySign(): This function will display the sign names on a ballot paper.

Select() : This function will select a sign.

GetConstituencyNo(): This function will return constituency number.

CountVotes(): This function will count the votes.

AnnounceResult(): This function will display result.

Note: The body of all member functions and destructors should be empty, while the constructors should have code which initializes the objects.

Lectures Covered: This assignment covers Lecture #07-10
Deadline: Your assignment must be uploaded/submitted at or before. May 07, 2013
