因此，我试图在Class Bank中添加带有vector的新帐户。对于从班级bankaccount派生的新帐户，例如班级检查和班级保存。
我无法弄清楚必须在void addaccount（）参数中放入哪种类型的参数，因此可以在下面的main函数中使用它。是否有可能我不必使用模板？据我了解，这是唯一的选择，因为我正在使用它来调用多个类类型。
Bank b;
b.addAccount(new CheckingAccount(12345, 18));
#include "pch.h"
#include <iostream>
#include <vector>
using namespace std;
class bankaccount {
int acctnum;
double balance;
public:
bankaccount(double newbalance=0.00, int newacctnum=0) { balance = newbalance; acctnum = newacctnum; }
int getacctnum() { return acctnum;}
double getbalance() { return balance; }
double setbalance(double newmoney) { balance += newmoney; }
void deposit(double newdepo) {
balance=getbalance() + newdepo;
}
void deposit(double newwith) {
balance = getbalance() - newwith;
}
};
class Savingaccount: public bankaccount
{
Savingaccount(int newacctnum, double rate):bankaccount(){
acctnum = newacctnum;
balance = getbalance() * (1 + rate);
};
void deposit(double newdepo) {
balance = getbalance() + newdepo;
}
void deposit(double newwith) {
balance = getbalance() - newwith;
}
};
class Checkingaccount : public bankaccount {
Checkingaccount(int newacctnum, double rate);
void deposit(double newdepo) {
balance = getbalance() + newdepo;
}
void deposit(double newwith) {
balance = getbalance() - newwith;
}
};
template <class T>
class Bank {
vector<T> x;
public:
void addaccount(T *temp);
void runmonthly();
};
int main() {
Bank b;
b.addAccount(new CheckingAccount(12345, 18)); //$18 monthly fee
b.addAccount(new SavingsAccount(12346, 0.02)); // 2% per month interest!
}
