친절한 답변해주셔서 감사합니다!!!!

대충 고쳐보긴했어요 ㅠㅠ

 

이제 여기서 credit(현재 잔액에 일정액을 더함) 과 debit(빚)을 만들어야 하는데요

 

private에다 넣어야 하나요? public에다 넣어야 하나요? 제생각은 public에 넣어야 할꺼 같은데.. 아닌가요? ㅠㅠ

 

 

 

#include <iostream>
using namespace std;

class account
{
private:
 int balance;

public:
 void setBalance()
 {
  cin >> balance;
  if (balance < 0)
  {
   cout << "Error : Initial balance cannot be negative" << endl;
   balance = 0;
  }
 }

 void getBalance()
 {
  cout << balance;
 }
};

void main()
{
 int a;
 account account1, account2;
 
 cout << "welcome to the bank!" << endl;
 cout << endl;
 cout << "Enter the initial balance" << endl;
 cout << "account 1 : ";
 account1.setBalance();
 cout << "account 2 : ";
 account2.setBalance();
 cout << endl;
 cout << endl;
 while (1)
 {
  cout << "1.Balance 2.Debit 3.Deposit 4.Withdrawal" << endl << "Number enter : ";
  cin >> a;
  switch (a)
  {
  case 1: //balance
   break;
  case 2: //debit
   break;
  case 3: //deposit
   break;
  case 4: //withdrawal
   break;
  }
 }
}
