This is C++ Programming

 

Given the following classes:

 

 

#include <iostream>

 

class Person

{

   char* name;

public:

   Person();

   Person(const char*);

   void setName(const char* nm);

   void display(std::ostream&) const;

   Person(const Person&); // copy constructor

   Person& operator=(const Person& src); // copy assignment

   ~Person();

};

 

class Student : public Person

{

   int no;

   float* grade;

   int ng;

   void init(int, int, const float*);

public:

   Student();

   Student(int);

   Student(const char*, int, const float*, int);

   Student(const Student&); // copy constructor

   Student& operator=(const Student& src); // copy assignment

   ~Student();

   void display(std::ostream&) const;

};

 

write implementation for the following functions (you can call other functions from these classes if you want assuming that they are implemented):

   ~Person();

   Person& Person::operator=(const Person& p);

   Student(const Student&);
