Question

到另一个程序。这是一个模拟银行账户的程序。我需要帮助显示余额，提款和存款。如何在取款/存款后显示最终余额？

#include <iostream>
#include <string>
#include "BACCOUNT.H"

    using namespace std;
    int main ()
    {
        double amount = 0.0;
        double withrdraw = 0.0;
        double deposit = 0.0;
        string name;
        double startamount = 100.00;
        double balance = 0.0;


        cout << "name: ";
        cin >> name;

        cout << "initial balance: " << startamount <<endl;


        cout << "deposit? ";
        cin >> amount;
        cout << "withdraw? ";
        cin >> amount;


        cout << "balance for " << name  << " is " << balance << endl;

        system ("pause");

        return 0;
    }

Answer 1

cout << "balance for " << name () << " is " << balance()
    <<endl;

通过在它们后面添加括号，您尝试调用name和balance类似函数，但它们是string。删除括号。

更重要的是，是什么让你认为必须在那里包括括号？可能有一个C ++的基本部分，你应该寻求完全理解（功能）。

Answer 2

您尝试在此处调用name和balance作为函数：

cout << "balance for " << name () << " is " << balance() <<endl;
                          ^^^^^^^              ^^^^^^^^^

但name是string而balance是double。此编辑将解决问题：

cout << "balance for " << name << " is " << balance <<endl;
