CS304 Object Oriented Programming Assignment No.4 Solution Spring Semester 2013


Consider Candidate class from E-Voting System discussed in Assignment No. 01. Class Details are given as follows:

Class Name

Attribute Name

Attribute Data Type

Functions

Candidate

CNIC

Integer/Character String

-Default constructor()

First_Name

Sponsored Links

Character String

-Function to overload stream extraction operator ( >>)

Last_Name

Character String

- Function to overload stream insertion operator ()

Sign_Alloted

Character String

-Function to overload comparison operator (= = )

Write a Program in C++ that implements the candidate class with given attributes and functions. Your program should be able to do the following:

There should be a default constructor to initialize data members of candidate class.

There should be a function to overload stream extraction operator so that we should take input for each object data members directly from main function using cin statement e.g. cin>>Candidate1.

Note: Make sure you take input against each data member specified in above table.

While inputting, you also have to check for duplicate records i.e. information of a single candidate should not be entered more than one. For this, you have to overload “= =” operator so that comparison operation would be performed on objects directly in main( ) function by writing this type of statement C1= = C2.

There should be a function to overload stream insertion operator so that we should display each object data directly from main function using cout statement e.g. . coutCandidate1.

In main() function, you are required to create an array of objects to store candidates information. For example if you want to register data of 5 candidates, you should create an array of 5 objects.
