In c++

Consider the following definition of the class studentType:

public 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);
void studentType(string fName = "", string lastName = "",
long id, 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 pure virtual functions.
