A. Consider the following definition of the

class studentType

class studentType: public personType

{

public:

void print();

void calculateGPA();

void setID(long id);

void setCourses(const string c[], int noOfC);

void setGrades(const char cG[], int noOfC);void getID();

void getCourses(string c[], int noOfC);

void getGrades(char cG[], int noOfC);

studentType(string fName = "", string lastName = "",long id=0, string c[] = NULL,char cG[] = NULL, int noOfC = 0);

private:

long studentId;

string courses[6];

char coursesGrade[6]int noOfCourses;

}

Rewrite the definition of the class studentType so that the functions print and calculateGPA are virtual functions.

B. Provide Implementation of the class in part A

C. Provide Test program.

PersonType is already implemented.

I have finished everything. but i cant make the tester file that test the virtual function, can you help me please..

I have the following code so far.

//personType.h

#ifndef H_personType

#define H_personType

#include

using namespace std;

class personType

{

public:

void print() const;

//Function to output the first name and last name

//in the form firstName lastName.

void setName(string first, string last);

//Function to set firstName and lastName according

//to the parameters.

//Postcondition: firstName = first; lastName = last

string getFirstName() const;

//Function to return the first name.

//Postcondition: The value of the data member firstName

// is returned.

string getLastName() const;

//Function to return the last name.

//Postcondition: The value of the data member lastName

// is returned.

personType(string first = "", string last = "");

//constructor

//Sets firstName and lastName according to the parameters.

//The default values of the parameters are empty strings.

//Postcondition: firstName = first; lastName = last

private:

string firstName;

//variable to store the first name

string lastName;

//variable to store the last name

};

#endif

//personType.cpp

#include "personType.h"

#include

using namespace std;

{

cout << firstName << " " << lastName << endl;

}

void personType::setName(string first, string last)

{

firstName = first;

lastName = last;

}

string personType::getFirstName() const

{

return firstName;

}

string personType::getLastName() const

{

return lastName;

}

personType::personType(string first, string last)

{

firstName = first;

lastName = last;

}

//this is tester file.. it is just rough work... can you test the virtual function ? by using pointer and dynamic variable.
