Question

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.

Answer 1

class studentType: public personType

{

public:

virtual void print() = 0;

virtual void calculateGPA() = 0;

void setID(long id) {

studentId = id;

}

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

noOfCourses = noOfC;

for (int i=0; i<noOfCourses; i++) {

courses[i] = c[i];

}

}

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

noOfCourses = noOfC;

for (int i=0; i<noOfCourses; i++) {

coursesGrade[i] = cG[i];

}

}

long getID() {

return studentId;

}

string* getCourses() {

return courses;

}

char* getGrades() {

return coursesGrade;

}

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;

};
