如何通过使用类调用main函数中的函数？

Question

#include <iostream>
using namespace std;

class Money
{
public:
Money();
Money(int, int);
void setDollars(int d);
void setCents(int c);
int getDollars() const;
int getCents() const;
double getAmount(int, int);

private: 
int dollars;
int cents;
};

Money::Money()
{
dollars = 0;
cents = 0;

}

Money::Money(int d, int c)
{
dollars = d;
cents = c;
}

void Money::setDollars(int d)
{
dollars = d;
}
void Money::setCents(int c)
{
if (c > 100)
{
    c = c % 100;
    dollars = dollars + (c / 100);
}
//update the dollars member if the cents input argument is 100 or larger. 
cents = c;
}

int Money::getDollars() const
{
return dollars;
}

int Money::getCents() const
{
return cents;
}


double Money::getAmount(int d, int c)
{
return dollars + (cents / 100);
}

int main()
{
int dlr;
int cts;
//double amt;

cout << "Please input amount of dollars: ";
cin >> dlr;
cout << "Please input amount of cents: ";
cin >> cts;

Money money0(dlr, cts);

cout << "The money object1 has amount: " << money0.getDollars() << "." << money0.getCents() << endl;
cout << "The money object2 has amount: " << money0.getAmount() << endl;
//I try to call the functions to tell user how much is it
//use both ways to tell user how much is it(1.getDollars+getCents, 2. getAmount)
return 0;
system("pause");
}

当我尝试在main中调用get函数时，错误会显示出来。如何正确调用这些功能？ 这是我的任务： 定义一个名为Money的类，用于存储货币金额。该类应该有两个私有整数变量，一个用于存储美元数，另一个用于存储美分数。包括一个默认构造函数，用于将金额初始化为$ 0.00，以及一个重载参数化构造函数，用于初始化任何非零金额（如下面的示例程序中所示）。
