Given the Person class definition below, write the destructor.

In person.h:
#ifndef PERSON_H
#define PERSON_H

#include <string>

using namespace std;

class Person{
 public:
  Person(const string& first, const string& last, int id);
  Person(const Person& rhs);
  const Person& operator=(const Person& rhs);
  string getFirst() const;
  string getLast() const;
  void setLast(const string& newLast);
  int getId() const;
  string toString() const;

 private:
  string* first;
  string* last;
  int id;
};

#endif

In person.cpp:
#include "Person.h"
#include <sstream>

using namespace std;

Person::Person(const string& first, const string& last, int id){
  this->first = new string(first);
  this->last = new string(last);
  this->id = id;
}

Person::Person(const Person& rhs){
  first = new string(*rhs.first);
  last = new string(*rhs.last);
  id = rhs.id;
}

const Person& Person::operator=(const Person& rhs){
  if( this != &rhs ){
    delete first;
    delete last;
    *first = new string(*rhs.first);
    *last = new string(*rhs.last);
    id = rhs.id;
  }

  return *this;
}

string Person::getFirst() const{
  return *first;
}

string Person::getLast() const{
  return *last;
}

void Person::setLast(const string& newLast){
  *last = newLast;
}

int Person::getId() const{
  return id;
}

string Person::toString() const{
  stringstream s;
  s << id;
  return s.str() + ": " + (*first) + " " + (*last);
}




See the solution below.


















Solution:
Person::~Person(){
  delete first;
  delete last;
}
