홍정모의 따라하며 배우는 C++
안녕하세요! Derived 객체에서 Base class로의 형변환 과정이 궁금해져서 질문을 남깁니다! 참고로 VS2022 를 사용하였습니다. #include <iostream> using namespace std; class Base { protected: int m_i; public: Base(int value) : m_i(value) { cout << sizeof(*this) << endl; } friend std::ostream& operator << (std::ostream& out, const Base& b) { out << &b << endl; out << "This is base output" << endl; return out; } }; class Derived : public Base { private: double m_d; public: Derived(int value) : Base(value) {} friend std::ostream& operator << (std::ostream& out, const Derived& d) { // derived는 base의 memory를 갖고 있기 때문에 가능함. out << static_cast<Base>(d); out << "This is derived output" << endl; return out; } }; int main() { Derived derived(7); cout << &derived << endl; cout << sizeof(derived) << endl; cout << derived << endl; return 0; } 먼저 class가 차지하는 size를 sizeof로 확인한 결과 Base는 4bytes, Derived는 16bytes(padding)으로 나왔습니다. 그다음 디버거를 통해 Derived의 주소를 통해 메모리에 들어있는 값을 확인한 후 Base의 연산자 오버로딩으로 넘어간 static_cast<Base> (d)의 주소를 들어가봤습니다. (위에 빨간 줄이 Base << 로 넘어간 후 static_cast<Base> (d)의메모리, 아래는 derived의 메모리) 결과 base << 는 reference로 받기 때문에 원본을 받아야하는데 주소가 다르게 나오고 값이 복사된 것을 확인할 수 있었습니다. 이 과정에서 어떤 부분이 복사하도록 관여한 것일까요? 한 가지 추측으로는 static_cast<>가 내부적으로 복사한 값을 base의 <<로 보내는 것이 아닌가 생각합니다!

Flutter 앱 개발 기초
안녕하세요. 선생님의 플러터 설치 가이드를 따라보며, 플러터를 새로 설치하였습니다. 맥북에어 m1 환경에서 설치하였는데, xcode설치 시, resetta라는 것을 설치하였습니다. 가이드에는 없는 내용이라 그러한데, rosetta가 무엇이고 이것을 설치해도 되는지요?

[질문 템플릿] 1. 강의 내용과 관련된 질문인가요? (예) 2. 인프런의 질문 게시판과 자주 하는 질문에 없는 내용인가요? (예) 3. 질문 잘하기 메뉴얼을 읽어보셨나요? (예) [질문 내용] AppConfig가 애플리케이션의 동작에 필요한 구현객체를 생성하고, 연결하는 별도의 설정 클래스라는것은 이해했는데, 강의 내용 보면 AppConfig가 애플리케이션의 전체 동작방식을 구성한다고 하였는데 여기서 말씀하시는 '애플리케이션의 전체 동작방식 구성' 이라는 의미가 무엇인지 모르겠어서요. 애플리케이션의 전체 동작방식 구성 = 애플리케이션의 동작에 필요한 구현객체생성, 연결 이렇게 이해하면될까요?

파이썬/장고 웹서비스 개발 완벽 가이드 with 리액트
안녕하세요. 장고를 활용하여 웹사이트를 만들고 있는 중입니다. 제가 지금 구현 중인 부분은 식단표 페이지로, 모델 단과 데이터 입력 단에서 막혀서 질문을 드립니다. 우선, "menu_list.html" 화면을 아래와 같이 띄우려고 합니다. 이를 위해 모델 구현부터 질문드리겠습니다. 첫번째 질문은 모델 구현에 대한 부분입니다. 최초 모델보다 수정 모델이 더 바람직한 방향인지 궁금합니다. #최초 model class Menu(models.Model): author = models.ForeignKey(User, on_delete=models.CASCADE, related_name='author_menu') date = models.DateField(unique=True) breakfast = models.TextField() lunch = models.TextField() dinner = models.TextField() voter = models.ManyToManyField(User, related_name='voter_menu') def __str__(self): return self.breakfast #수정 model TYPE_CHOICES = ( ("아침", "아침"), ("브런치", "브런치"), ("점심", "점심"), ("저녁", "저녁"), ) class Dish(models.Model): dish = models.CharField(max_length=10) voter = models.ManyToManyField(User) def __str__(self): return self.dish class Menu(models.Model): type = models.CharField(choices=TYPE_CHOICES, max_length=3) date = models.DateField() dish = models.ManyToManyField(Dish) 최초 모델은 아무런 고민 없이 TextField로 식사 정보를 모두 받아왔으나 성능 측면에서 비효율적일 수 있다는 생각이 들어 고민을 하고 수정하였습니다. 수정된 설계가 더 바람직한 것인지 의문이 들어 질문드립니다. 더 바람직한 방향이 있다면 가르쳐주세요!! 두번째 질문은, 수정된 model을 통해 값을 받아오는 것에 대해 질문드리고 싶습니다. #forms.py TYPE_CHOICES = ( ("아침", "아침"), ("브런치", "브런치"), ("점심", "점심"), ("저녁", "저녁"), ) class DishMenuForm(forms.Form): date = forms.DateField(widget=forms.DateInput(attrs={'type': 'date'}, format="%Y-%M-%d"),label='date') type = forms.ChoiceField(choices=TYPE_CHOICES, label='type') dish = forms.CharField(label='dish', max_length=10) def save(self, commit=True): menu = Menu(**self.cleaned_data) if commit: menu.save() return menu #menu_form.html {% extends 'layout.html' %} {% load static %} {% block content %} <script src ="{% static 'js/menu.js' %}"></script> <div class="container"> <h5 class="my-3 border-bottom pb-2">메뉴 입력하기</h5> <form method="post"> {% csrf_token %} <div id ="dishMenuForm"> <div class="mb-3"> <label for="date" class="form-label">날짜</label> <input type="date" class="form-control" name="date" id="date" width='50px'> </div> <div class="mb-3"> <label for="breakfast" class="form-label">아침</label> <select name='type' id ='type' class='form-control'> <option value="">시간대를 정해주세요.</option> <option value='아침'>아침</option> <option value='점심'>점심</option> <option value='저녁'>저녁</option> <option value='브런치'>브런치</option> </select> </div> <div class="mb-3"> <label for="dish" class="form-label">요리</label> <textarea class="form-control" name="dish[]" id="dish" rows="1"></textarea> </div> <div class="mb-3"> <label for="dish" class="form-label">요리</label> <textarea class="form-control" name="dish[]" id="dish" rows="1"></textarea> </div> <div class="mb-3"> <label for="dish" class="form-label">요리</label> <textarea class="form-control" name="dish[]" id="dish" rows="1"></textarea> </div> </div> <input type='submit' value='입력' /> </form> </div> {% endblock %} 사진처럼 form.html 화면에서 dish의 form들을 동적으로 추가하여 저장하고 싶습니다. 템플릿 파일에서 dish의 name을 배열로 받아와 view 단에서 반복문을 사용하여 데이터를 저장할 수 있는지 궁금합니다. 성능을 위해 매번 데이터를 저장할때마다 dish 테이블에 이미 값이 있는지를 확인하고 저장해야하는 것인지, 데이터를 저장할때마다 분기를 돈다면 성능에 더 악영향을 미칠 것 같은데 어떤 방향으로 개발해야 하는지 궁금합니다. 이런 식의 방향이 맞는지 아니면 더 잘 쓰이는 방법이 있는지 알려주세요.. 질문이 길고 장황하지만 답변 부탁드립니다.
