Question

Write a C++ program that asks the user to enter the price of a car (real), the down
payment (real) and the number of years for the loan (integer). Calculate and output
the monthly payment (real) of that car. Assume the sales tax rate is 7% and an
interest rate is 9%. Use constant declarations for these rates.

//Question #42085, Programming, C++#include <iostream>using namespace std;int main () {   const float salesTaxRate = 7;   const float interestRate = 9;   float price;   float downPayment;   int numberOfYears;   float monthlyPayment = 0;   cout << "Please enter the price of the car :\n";   cin >> price;      cout << "Please enter down payment :\n";   cin >> downPayment;   cout << "Please enter the number of years for the loan :\n";   cin >> numberOfYears;   price += price*(salesTaxRate / 100); //add to the price  the tax for the sale   price -= downPayment;// price without downPayment   price += price*(interestRate/100); // add to the price interest Rate   monthlyPayment = price / (numberOfYears*12);   cout << "You will pay " << monthlyPayment << " in a month.\n";   return 0;}
