Hack 1

public class Hack1 {
    public static void main(String[] args) {
        int cars = 0; // starting number of cars
        int numCarsEntering = 2; // number of cars entering at a time
        int numIterations = 5; // number of times to loop
        for (int i = 0; i < numIterations; i++) {
            cars += numCarsEntering; // use compound operator to add cars
            System.out.println("Number of cars on highway: " + cars);
        }
        System.out.println(cars * 4);
    }
}

Number of cars on highway: 2
Number of cars on highway: 4
Number of cars on highway: 6
Number of cars on highway: 8
Number of cars on highway: 10
