解答:
main.cpp

#include <iostream>
#include "BankAccount.h"
using namespace std;int main()
{BankAccount BA1("韩立","韩跑跑",1);BA1.get_info();BankAccount BA;BA.init_account("姚国林", "amdin", 10000);BA.get_info();BA.deposit(1000);BA.get_info();BA.withdraw(2000);BA.get_info();return 0;
}

BankAccount.h

#pragma once
#include <iostream>
using namespace std;

public:BankAccount();BankAccount(const string name, const string id, double bal);~BankAccount();void init_account(const string name, const string id, double bal);void get_info()const;void deposit(double cash);void withdraw(double cash);
};

BankAccount.cpp

#include "BankAccount.h"BankAccount::BankAccount()

}
BankAccount::BankAccount(const string name, const string id, double bal)
{this->fullname = name;this->accid = id;this->balance = bal;
}

}
void BankAccount::get_info()const
{cout << "姓名为:" << this->fullname << endl;cout << "账号为:" << this->accid << endl;cout << "存款为:" << this->balance << endl;
}
void BankAccount::deposit(double cash)
{this->balance += cash;
}
void BankAccount::withdraw(double cash)
{this->balance -= cash;
}
