(Modify the Loan class) Rewrite the Loan class in Listing to add two static functions for computing monthly payment and total payment, as follows:

double getMonthlyPayment(double annualInterestRate,  int numberOfYears, double loanAmount)

double getTotalPayment(double annualInterestRate,  int numberOfYears, double loanAmount)

Write a client program to test these two functions.

#ifndef LOAN_H#define LOAN_H

class Loan{public    :Loan();   Loan(double rate, int years, double amount);   double getAnnualInterestRate();   int getNumberOfYears();   double getLoanAmount();   void setAnnualInterestRate(double rate);   void setNumberOfYears(int years);   void setLoanAmount(double amount);   double getMonthlyPayment();   double getTotalPayment();

private :   double annualInterestRate;

   int numberOfYears;   double loanAmount;

};

#endif
