(3 pts) Suppose that the Loan class is given as shown in the following UML. Write a test program that creates a Loan object with loan amount $40000, annual interest rate 5.5%, and number of years 15, and displays the monthly payment and total payment.

```
#include
#include "Loan.h"

using namespace std;

int main()
{
Loan loan(5.5, 15, 40000);
cout << "Monthly payment: " << loan.getMonthlyPayment() << endl;
cout << "Total payment: " << loan.getTotalPayment() << endl;
return 0;
}
```
