3. QA

5. 상속 관계
(is a 관계)
구체화
일반화

7. void Attack(Robot* pRobot);
Attack(태권브이);
Attack(건담);
Attack(트랜스포머);
Attack(아이기스)
A is B
A는 B 역할을 할수 있다.
B자리에 A가 들어가도 된다.

8. void ExamMain::TestPolymorph1()
{
CCharacter character;
CMob* pMob = new CMob();
CNPC* pNPC = new CNPC();
Elf* pElf = new Elf();
DarkElf* pDarkElf = new DarkElf();
character.Attack(pMob);
character.Attack(pNPC);
character.Attack(pElf);
character.Attack(pDarkElf);
}

9. std::vector<CCharacter> characters;
Elf newElf;
DarkElf newDarkElf;
characters.push_back(newElf);
characters.push_back(newDarkElf);
// C++ 11 Range based for
for (auto charac : characters)
{
charac.SayMyName();
}

10. std::vector<CCharacter> characters;
Elf newElf;
DarkElf newDarkElf;
characters.push_back(newElf);
characters.push_back(newDarkElf);
// C++ 11 Range based for
for (auto charac : characters)
{
charac.SayMyName();
}
객체의 불필요한 복사(Copy)가
일어난다!!

11. CCharacter::CCharacter(void)
{
m_Name = "Character";
printf_s("Character is Created!!n");
}

12. class CCharacter
{
public:
CCharacter(void); // 기본 생성자
CCharacter(const CCharacter& src); // 복사 생성자
virtual ~CCharacter(void);
CCharacter::CCharacter( const CCharacter& src )
{
m_Name = src.m_Name;
printf_s("%s is Copy!! n", m_Name.c_str());
}

14. STL Vector – 주의할 점

15. STL Vector – Capacity
Capacity
벡터가 담을 수 있는 용량.
Capacity를 넘어 간다면??

16. STL Vector – Capacity
1
2
3
4
Capacity : 4
5
Capacity : 8
새로운 공간을 할당한다
새로운 공간에 값을 복사한다

17. STL Vector – Capacity

18. STL Vector – Capacity

19. STL Vector – reserve
미리 공간을 할당한다
-> 재할당이 일어나지 않는다

20. STL Vector – resize

21. std::vector<CCharacter*> characters;
Elf* pElf = new Elf();
DarkElf* pDarkElf = new DarkElf();
characters.push_back(pElf);
characters.push_back(pDarkElf);
// C++ 11 Range based for
// 객체가 복사(Copy) 된다.
for (auto charac : characters)
{
charac->SayMyName();
}

23. std::vector<CCharacter*> characters;
Elf* pElf = new Elf();
DarkElf* pDarkElf = new DarkElf();
characters.push_back(pElf);
characters.push_back(pDarkElf);
// C++ 11 Range based for
// 객체가 복사(Copy) 된다.
for (auto charac : characters)
{
charac->SayMyName();
}
for (auto charac : characters)
{
delete charac;
}
characters.clear();
