Solve in C++ for Car.h and Car.cpp

8.21 LAB: Car value (classes) Given main, complete the Car class (in files Car hand Car.cpp) with member functions to set and get the purchase price of a car (SetPurchase Price().GetPurchase Price)and to output the car's information (Printinfo). Ex If the input is 2011 18000 2018 where 2011 is the car's model year, 18000 is the purchase price, and 2018 is the current year, the output is Car's information Model year: 2011 Purchase price: 18000 Current value: 5770 Note: printinfo/ should use three spaces for indentation LAB ACTIVITY 8 21.1: LAB: Car value (classes) 0/8 File is marked as read only Current file main.cpp - I 1 include <iostream 2 include "Car.h" using namespace std; 5 int main(int args, const chart 1) int user Year: int user price; int userCurrent Year CarryCars cin >> user Years cin >> UserPrice: 13 cin >> userCurrentYear; yCar.setModel Year(server); myCar.SetPurchase price(user Price) wyCar.CalcCurrentValue(userCurrent Year) myCar. PrintInfo(); return; 22 )

Car.h

#ifndef CARH
#define CARH

class Car{
private:
int modelYear;
  
int purchasePrice;
int currentValue;

public:
void SetModelYear(int userYear);
int GetModelYear() const;
void SetPurchasePrice(int purchasePrice);
int GetPurchasePrice() const;

void CalcCurrentValue(int currentYear);
void PrintInfo();
};
#endif // CARH

Car.cpp

#include<iostream>
#include<math.h>
#include "Car.h"
using namespace std;

void Car::SetModelYear(int userYear){

int Car::GetModelYear() const{

}

void Car::SetPurchasePrice(int userPrice){

}

int Car::GetPurchasePrice() const{

}

void Car::CalcCurrentValue(int currentYear){
double depreciationRate = 0.15;
int carAge = currentYear- modelYear;

currentValue = (int)round(purchasePrice*pow((1-depreciationRate),carAge));

}

void Car::PrintInfo(){
cout<<"Car's information:\n";
cout<<"\t\tModel Year : "<<GetModelYear();
cout<<"\n\t\tPurchase price: "<<GetPurchasePrice();
cout<<"\n\t\tCurrentValue: "<<currentValue;
