了解重载运算符。收到"non-standard syntax; use '&' to create a pointer to a member"错误

我正在尝试创建一个使用重载运算符的简单程序。我相信我的那部分是正确的。但是，当我尝试在"Money"类中调用"getDollar"函数时，会出现"非标准语法；使用'&'创建指向成员的指针"错误。我错过了什么？

谢谢你的帮助。（代码张贴在下面）

驱动程序.cpp

#include <iostream>

    cout << "Please enter in a monetary value:n" << "Dollars: ";
    cin >> dollars;
    cout << "nCents: ";
    cin >> cents;
    Money a(dollars, cents);
    cout << "Please enter in second monetary value:n" << "Dollars: ";
    cin >> dollars;
    cout << "nCents: ";
    cin >> cents;
    Money b(dollars, cents);
    Money& c = a + b;
    cout << "nThe amount of the two added together are " << c.getDollars << "." << c.getCents << endl;
    c = a - b;
    cout << "nThe amount of the first value subtracted by the second value is " << c.getDollars << "." << c.getCents << endl;
