Question

Hi, I need to write a program for linux (putty) and please read carefully (I've asked the same question 3 times because the experts who answered my questions wrote their own carmain1.cpp file. Please leave it where it is and only create car.cpp and car.h files.)

Exercise 1: Car class (5 points) Create a header file ( car.h ) with a class definition for a Car object. A Car object will have three member variables: a make (string) a model(string) a year(int). After creating the class definition, create a car.cpp file and implement the member functions in the class definition. NOTE: You will need a 'getter' and a 'setter' for each member variable. Download the carmain1.cpp file from d2l and test your class by putting all files inside one directory and compiling them with: g++ *.cpp -o prog Requirements: All member variables are private. All member variables have a corresponding getter and setter member function. See carmain1.cpp for what these should be called. There should be TWO files to submit: a car.cpp file and a car.h file. Put these in a directory called 'week3exer1'. Use carmain1.cpp for testing as I will be using this file to test your submission (don't write your own).

Here's carmain1.cpp

/* carmain1.cpp
* Please don't rewrite this file
* I will be using the exact
* same file below when grading

*/

#include <iostream>
#include "car.h"

using namespace std;

int main()
{
   Car sedan;

// input
string imake;
string imodel;
int iyear;

// output
string omake;
string omodel;
int oyear;
  
// getting values before setting them.
// This may produce garbage values. We will be
// fixing this in exercise 2.
cout << "Sedan before initialization: " << endl;
omake = sedan.getMake();
cout << "Make: " << omake << endl;

omodel = sedan.getModel();
cout << "Model: " << omodel << endl;

oyear = sedan.getYear();
cout << "Year: " << oyear << endl;
  
//set the values for sedan
cout << "Setting values for sedan: " << endl;
cout << "Enter make: ";
getline(cin, imake);
sedan.setMake(imake);

cout << "Enter model: ";
getline(cin, imodel);
sedan.setModel(imodel);
  
cout << "Enter year: ";
cin >> iyear;
cin.ignore(200, '\n');
sedan.setYear(iyear);

// getting the data back out
cout << "printing values for sedan: " << endl;
omake = sedan.getMake();
cout << "Make: " << omake << endl;

omodel = sedan.getModel();
cout << "Model: " << omodel << endl;

oyear = sedan.getYear();
cout << "Year: " << oyear << endl;
  
return 0;   
}

//Output
