프갤에서 조공은 덕짤로 해야한다는 걸 보고 덕짤? 하나 구해다 올립니다


이 밑은 제가 짠 C++ 주소록인데요

structure 안에 class 를 만들고 private로 합니다

이제 정보 입출력은 private 로 왔다갔다 하는데여

그리고 그 명령어는 structure 안에 public void 이걸로 하구요

근데 문법? 을 모르겠네요. class 안에 정보를 받기 위해서

void addressInput

안에 classA[number].firstName 이 부분이랑

역시 void addressOutput

classA.addbook[100]

addbook[n].firstname 이 부분들 

다 에러나네요


어떻게 수정해야하죠?

무림고수님들 도와주세용
