열혈 C++ 프로그래밍 OOP 프로젝트 05

프로젝트 기능 제공의 핵심이 되는 컨트롤 클래스 정의

AccountHandler 클래스를 정의하고 앞에서 정의한 전역함수들을 클래스에 멤버함수로 포함

#include <iostream>
#include <cstring>
using namespace std;

// 02 class추가, 객체 포인터 배열 추가
// 03 복사 생성자 추가, 소멸자 추가
// 04 Account 클래스내의 const선언이 가능한 멤버함수에 const선언
// 05 전반적인 기능을 담당하는 Handler 컨트롤 클래스 추가

enum { MAKE = 1, DEPOSIT, WITHDRAW, INQUIRE, EXIT };
