Question

Consider the following c++ code and answer the question?

class Personal
{ int Class,Rno;
char Section;
protected:
char Name[20];
public:
personal();
void pentry();
void Pdisplay(); };
class Marks:private Personal
{ float M{5};
protected:
char Grade[5];
public: Marks();
void Mentry();
void Mdisplay(); };
class Result:public Marks
{
float Total,Agg;
public:
char FinalGrade, Commence[20];
Result();
void Rcalculate();
void Rdisplay();
};

Give the sequence of Constructor/Destructor Invocation when the object of class Result is created.

Answer 1

Personal (); // constructor of class personal
Marks (); // constructor of class marks
Result (); // destructor of class Result
Marks (); // destructor of class marks
Personal (); // destructor of class personal
