使用向量的银行账户(存款和取款）

我正在做一个项目，该项目应该允许您创建 3 个表单(名称、帐号、余额(的帐户，然后为您提供以下选项：

1( 添加帐户。

2(关闭和现有帐户。

3(存入一定金额。

4( 提现账户

5(没有要求。

到目前为止，我能够成功创建3个帐户，显示它们，添加另一个帐户，再次显示它们，删除一个帐户并再次显示它们。但是，我无法找到从特定帐户存款或取款的方法。所以要清楚，我的问题是：我如何访问所选账户的余额并存入/提取金额(请记住，我正在使用向量来保存所有账户(？

以下是我的代码：

主.cpp

#include "bank.hpp"

void deleteaccount (vector<bank>&);
int main() {
vector<bank> mybank;
fillaccounts(mybank);
for (int i=0;i<5;i++) {
cout << "Please choose one of the following requests: " << endl;
cout << "(1) Create a new account." << endl;
cout << "(2) Close an existing account." << endl;

        break;
    case 4:

    newmybank.push_back(newAccount);

    cout << "(" << newmybank[i].getname() << "," <<    newmybank[i].getaccountnumber() << "," << newmybank[i].getbalance() << ")" << endl;
}
cout << endl;
}

void deleteaccount(vector<bank>& newmybank) {

cout << "Please enter your name to delete your account: " << endl;
cin >> name;
cout << endl;
for (int i=0; i<newmybank.size(); i++) {
    if (newmybank[i].newname == name) {
        newmybank.erase(newmybank.begin()+i);
    }
}
}

关于如何跟进的任何建议？谢谢你们！
