Answer 1

int yearName[]; // array for string marks 
string subjectName[]; // array for storin g subject names

컴파일러가 표준을 준수하면이 두 줄을 컴파일해서는 안됩니다.

사용 std::vector :

std::vector<int> yearName; 
std::vector<string> subjectName; 

한 다음에 요소를 추가 할 push_back 기능을 사용하십시오.

Year(string sone, string stwo, string sthree, /*...*/) 
{ 
     subjectName.push_back(sone); 
     subjectName.push_back(stwo); 
     subjectName.push_back(sthree); 
     //so on  
}
