Question

C++ Program

1a. Purpose

Practice the creation and use of a Class

1b. Procedure

Write a class named Car that has the following member variables:

• year. An int that holds the car’s model year.

• make. A string object that holds the make of the car.

• speed. An int that holds the car’s current speed.

In addition, the class should have the following member functions.

• Constructor. The constructor should accept the car’s year and make as arguments and assign these values to the object’s year and make member variables. The constructor should initialize the speed member variable to 0.

• Accessors. Appropriate accessor functions should be created to allow values to be retrieved from an object’s year, make, and speed member variables.

• accelerate. The accelerate function should add 5 to the speed member variable each time it is called.

• brake. The brake function should subtract 5 from the speed member variable each time it is called.

Demonstrate the class in a program that creates a Car object and then calls the accelerate function five times. After each call to the accelerate function, get the current speed of the car and display it. Then, call the brake function five times. After each call to the brake function, get the current speed of the car and display it.

#include <iostream>
#include <string>

using namespace std;

class Car {
private:
    string make;
    int speed;
    int yearModel;
public:
    // constructor for Car
    Car(int yearModel, string make) {
        this->yearModel = yearModel;
        this->make = make;
        speed = 0;
    }

    // getter for make
    string getMake() {
        return make;
    }

    // getter for speed
    int getSpeed() {
        return speed;
    }

    // getter for year
    int getYearModel() {
        return yearModel;
    }

    // accelerate car
    void accelerate() {
        speed += 5;
    }

    // brake the car
    void brake() {
        speed -= 5;
    }
};

int main() {
    // Create a car object.
    Car car(2019, "Ferrari");
    // Accelerate five times.
    int count;
    for (count = 0; count < 5; count++) {
        // Accelerate and display the speed.
        cout << "Accelerating...\n";
        car.accelerate();
        cout << "Current speed: " << car.getSpeed() << endl;
    }
    // Brake five times.
    for (count = 0; count < 5; count++) {
        // Brake and display the speed.
        cout << "Braking...\n";
        car.brake();
        cout << "Current speed: " << car.getSpeed() << endl;
    }
    cout << "Testing the " << car.getMake() << " made in " << car.getYearModel() << endl;
    return 0;
}
