Chapter 4: A Very Functional Program

In this project, we will create a program consisting of multiple functions to represent a car driving.

With functions, we can combine them to perform, well, really anything! Let's create a function to create a new car:

func new_car() {

    give "Jeep Grand Cherokee"; # use 'give' to return values from a function 

}

Since this function gives us a new car as a string, let's add a way to make the car drive!

func start_driving(car) {

    bark("Car '" + car + "' is driving");

}

Also make sure to add the stop function:

func stop_driving(car) {

    bark("Car '" + car + "' has been stopped");

}

Now, we can combine it all together and call all the appropriate functions:

obj my_car = new_car();

start_driving(my_car);

stop_driving(my_car);

The final code should look something similar to this:

func new_car() {

    give "Jeep Grand Cherokee";

}

func start_driving(car) {

    bark("Car '" + car + "' is driving");

}

func stop_driving(car) {

    bark("Car '" + car + "' has been stopped");

}

obj my_car = new_car();

start_driving(my_car);

stop_driving(my_car);
