[C언어|C++] C++만들면서 배우기01 / 만들면서 배우는 C++ 학생 출력하기

💡 글 작성자는 vscode를 활용하여 Python을 작성하고있습니다.

 

해당글에는 QList (QT)를 활용하였습니다. 

만약 C++로만 하는 경우에는 vector로 변경하면 됩니다.

💡 Main.cpp

#include <iostream>

    Student *donggyu = new Student("동규");
    Student *mansu = new Student("동글");

    donggyu->subList->append(new Subject("국어", 100));
    donggyu->subList->append(new Subject("수학", 100));
    donggyu->subList->append(new Subject("영어", 100));

    mansu->subList->append(new Subject("국어", 100));
    mansu->subList->append(new Subject("수학", 100));
    mansu->subList->append(new Subject("영어", 100));
    
    sch->schlist->append(donggyu);
    sch->schlist->append(mansu);

    cout << "학교: " << sch->getName() << endl;
