깊은 복사

 

 

ex00에서 파일 그대로 복사하고 추가해야될 파일은 Brain.cpp Brain.hpp, 수정해야될 파일은 Dog.cpp, Cat.cpp

1. Brain.hpp Brain.cpp 만들기

#ifndef BRAIN_HPP
# define BRAIN_HPP

#include "iostream"

class Brain {
private:
	std::string ideas[100];
public:
	Brain();
	Brain(std::string idea);
	Brain(Brain const &brain);
	~Brain();
	Brain &operator=(Brain const &brain);
	std::string getIdea(int index) const;
	void setIdea(int index, std::string str);
};

#endif

#include "Brain.hpp"

Brain::Brain(void) {
	std::cout << "Brain Constructor called\\n";
	for (int i = 0; i < 100; i++)
	{
		this->ideas[i] = "nothing";
	}
}
Brain::Brain(std::string idea) 
{
	std::cout << "Brain Constructor called\\n";
	for (int i = 0; i < 100; i++)
	{
		this->ideas[i] = idea;
	}
}

Brain::Brain(Brain const &brain) {
	*this = brain;
}

Brain::~Brain(void) {
	std::cout << "Brain Destructor called\\n";
}

Brain& Brain::operator=(Brain const &brain) {
	if (this == &brain) 
		return *this;
	for (int i = 0; i < 100; i++) {
		this->ideas[i] = brain.getIdea(i);
	}
	return (*this);

}

std::string Brain::getIdea(int index) const
{
	return this->ideas[index];
}

void Brain::setIdea(int index, std::string str)
{
	ideas[index] = str;
}

1. Dog.cpp, Cat.cpp 수정

Cat

#include "Cat.hpp"

Cat::Cat(void)
{
	this->type = "Cat";
	this->brain = new Brain();
	std::cout << "Cat Constructor called\\n";
}

Cat::Cat(Cat const &cat)
{
	this->brain = new Brain();
	*this = cat;
	std::cout << "Cat Constructor copy called\\n";
}

Cat::~Cat()
{
	delete brain;
	std::cout << "Cat Destructor called\\n";
}

Cat& Cat::operator=(Cat const &cat)
{
	if (this == &cat)
		return *this;
	this->type = cat.getType();
	if (this->brain)
	{
		delete this->brain;
	}
	this->brain = new Brain(*(cat.brain));
	std::cout << "Cat operator = " << type << " called\\n";
	return (*this);
}

std::string Cat::getCatIdea(int index)
{	
	if (index >= 100)
	{
		std::cout << "99 out of range\\n";
		return "";
	}
	return brain->getIdea(index);
}

void Cat::setBrain(int index, std::string str)
{
	if (index >= 100)
	{
		std::cout << "99 out of range\\n";
		return ;
	}
	brain->setIdea(index, str);
}

void Cat::makeSound(void) const 
{
	std::cout << "nyang\\n";	
}

Dog

#include "Dog.hpp"
#include "Brain.hpp"

Dog::Dog(void)
{
	this->type = "Dog";
	this->brain = new Brain();
	std::cout << "Dog Constructor called\\n";
}

Dog::Dog(Dog const &dog)
{
	this->brain = new Brain();
	*this = dog;
	std::cout << "Dog Constructor copy called\\n";
}

Dog::~Dog()
{
	delete brain;
	std::cout << "Dog Destructor called\\n";
}

Dog& Dog::operator=(Dog const &dog)
{
	if (this == &dog)
		return *this;
	this->type = dog.getType();
	if (this->brain)
	{
		delete this->brain;
	}
	this->brain = new Brain(*(dog.brain));
	std::cout << "Dog operator = " << type << " called\\n";
	return (*this);
}

std::string Dog::getDogIdea(int index)
{	
	if (index >= 100)
	{
		std::cout << "99 out of range\\n";
		return "";
	}
	return brain->getIdea(index);
}

void Dog::setBrain(int index, std::string str)
{
	if (index >= 100)
	{
		std::cout << "99 out of range\\n";
		return ;
	}
	brain->setIdea(index, str);
}

void Dog::makeSound(void) const 
{
	std::cout << "meong\\n";	
}
