c++로 은행시스템구현중인데 에러는안나지만 의도한대로 안되네요.

도움 주시면 감사하겠습니다.

 

질문1.

account클래스의 잔액(balance)과 checkingaccount, creditlineaccount 이 클래스들의 잔액을 서로 같게 해주고싶은데

어떻게해야하죠? 전 지금 완전따로따로 노네요..

마찬가지로 계좌주 계좌번호같은것들도요..

 

질문2.

코드상으론 이상없는거 같은데 막상 실행하고 나면은 account메뉴에서 4번을 누르면 잔액조회만 되야하는데 잔액조회후 checkingaccount 메뉴로 넘어가네요.

마찬가지로 checkingaccount 메뉴에서 4번을 누르면 잔액조회만 되야하는데 잔액조회후 creditlineaccout 메뉴로 넘어가네요.

checkingaccount 메뉴에서 4번을 누르면 잔액조회만 되야하는데 잔액조회후 account 메뉴로 넘어가네요.

서로 돌고도는 시스템같은데;; a->b->c->a 이런식으로. 왜 이런거죠? 코드엔 이상없는거같은데;

 

 

p.s 추후 파일입출력도 할거구요. 이외에도 다른이상이 있는지 봐주시면 감사하겠습니다.

 

p.s2 account // 일반계좌클래스

      checkingaccount  // 체크카드 계좌클래스

      creditlineaccoumt  // 마이너스통장 계좌클래스
