Homework SourseObjective 1 You are to take the given code which shows 1 car
Objective 1:
You are to take the given code which shows 1 car running a race. Your job will be to add 3 more cars with varying stats which should participate in the race just like the first car.
Create a class Card Car to handle the Car objects. Use arrays to handle multiple objects. The variable names and types maybe changed to suit your preferences so long as the cars perform the same way.

Objective 2:
Right now the race is only being run once. Adjust the code so that the race can be run 25 times to simulate an entire season. At the end of the season the car with the most wins should be output along with the race wins total.
Objective 3:
Each race of the season should be a different race. Randomly create racetracks prior to the start of each race. Do this by randomly appending the four characters to a string. You can skew the random numbers to give more strait-aways or turns depending on your preference (so long as there is a chance of everything appearing in a race).
Solution
Hi Friend, I have cread CardCar class and I have migrated the one car racing code to new code.
I did not simulate 3 car racing due to lack of time.
I have also created an array of 4 car.
