CS304 Object Oriented Programming Assignment 2 Solution Spring May 2013

Composition and Aggregation is an important relationship between objects in object oriented paradigm. Consider the following class diagram, which shows some classes and their relationship (Composition and Aggregation), while the detail of classes is given in the table.

Class Name	Attribute Name	Attribute Data Type	Functions
Sign	Name	Character String	-Constructor
			-Getters and Setters
Candidate	Name	Character String	-Default constructor()
	Votes_obtain	Integer	-Overloaded Constructor
	sign	Sign	-Getters and Setters
			-Count_votes()
Constituency	ConNo	Character String	-Default constructor()
	Candidate_name	Cadidate	-Overloaded Constructor
			-Getters and Setters
Result	DayOf_result	Character String	-Default constructor
			-Getters and Setters
			-compile_result()
VB_Paper	CanName	Candidate	-Default constructor
	res	Result	-Overloaded Constructor
			-Getters and Setter
			-Get_result()

You are required to implement this class diagram (Write complete program) in to C++ with all functions and concepts (Aggregation and composition) given in the class diagram/table.
You need to consider that there may be two or more than two candidates who can contest in the constituency.

Details of important Member functions:
Count_votes(): This function will count votes of each candidate.
compile_result() : This function will Compile (calculate) the result of the contesting candidates.
Get_result(): This function will get/show result from the Result class through the part object “res” of the VB_Paper class.
