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.

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;

};

Explanation:

Code rewritten

the answer would be 2

since they are only saying that the couple has 20 daughters and so on but they never said that they went to the movies as well therefore the couple was the only people that went to the movies.

hope this ! : 3
