Need help with this code.

I need this code to compile and run.

Code:

#include

#include

#include "personType.h"

using namespace std;

const int NO_OF_REGIONS = 4;

class candidateType : public personType

{

public:

const candidateType& operator=(const candidateType&);

//Overload the assignment operator for objects of the

//type candidateType

const candidateType& operator=(const personType&);

//Overload the assignment operator for objects so that

//the value of an object of type personType can be

//assigned to an object of type candidateType

void updateVotesByRegion(int region, int votes);

//Function to update the votes of a candidate for a

//particular region.

//Postcondition: Votes for the region specified by the

// parameter are updated by adding the votes specified

// by the parameter votes.

void setVotes(int region, int votes);

//Function to set the votes of a candidate for a

//particular region.

//Postcondition: Votes for the region specified by the

// parameter are set to the votes specified by the

// parameter votes.

void calculateTotalVotes();

//Function to calculate the total votes received by a

//candidate.

//Postcondition: The votes in each region are added and

// assigned to totalVotes.

int getTotalVotes() const;

//Function to return the total votes received by a

//candidate.

//Postcondition: The value of totalVotes is returned.

void printData() const;

//Function to output the candidate's name, the votes

//received in each region, and the total votes received.

candidateType();

//Default constructor.

//Postcondition: Candidate's name is initialized to blanks,

// the number of votes in each region, and the total

// votes are initialized to 0.

//Overload the relational operators.

bool operator==(const candidateType& right) const;

bool operator!=(const candidateType& right) const;

bool operator<=(const candidateType& right) const;

bool operator<(const candidateType& right) const;

bool operator>=(const candidateType& right) const;

bool operator>(const candidateType& right) const;

private:

int votesByRegion[NO_OF_REGIONS]; //array to store the votes

// received in each region

int totalVotes; //variable to store the total votes

};

void candidateType::setVotes(int region, int votes)

{

votesByRegion[region - 1] = votes;

}

void candidateType::updateVotesByRegion(int region, int votes)

{

votesByRegion[region - 1] = votesByRegion[region - 1] + votes;

for (int i = 0; i

totalVotes += votesByRegion[i]; //adding each region votes to totalVotes

}

void candidateType::calculateTotalVotes()

{

}

int candidateType::getTotalVotes() const

{

return totalVotes;

}

void candidateType::printData() const

{

cout << left << setw(10) << firstName << " " << setw(10) << lastName << " ";

cout << right;

for (int i = 0; i < NO_OF_REGIONS; i++)

cout << setw(7) << votesByRegion[i] << " ";

cout << setw(7) << totalVotes << endl;

}

candidateType::candidateType()

{

for (int i = 0; i < NO_OF_REGIONS; i++)

votesByRegion[i] = 0;

totalVotes = 0;

}

bool candidateType::operator==(const candidateType& right) const

{

return (firstName == right.firstName

&& lastName == right.lastName);

}
