To emulate the horse race I have written a class$/$method for you called Race. For Python see the lecture Lists$-$randomize and corresponding class notes which scrambles the horses. For java you can look for the Race Google Doc which has the class. For C I just have a function that will do it using a Fisher Yates algorithm to scramble them. You can also dig in the class notes for Midterm hints, and I will try to post some newly recorded midterm hints in the week ahead for you.

Make a program that takes bets on horse races. There will be four types of bets described below. The horse race result is generated by a function called ReadySetgo that simply scrambles the horses into random order as a $$pseudo$/$simulated$$ horse race and that tells you the race results. I will provide you with the code for the Race function.

We assume four horses run in a race $($though you want to write it so it would be fairly easy to change teh number of horses$),$ and we assume the horses are named by numbers $1-4.$ Advanced students if you feel adventurous you can $($but are not obligated to$)$ give the horses more creative names and make the number of horses running in the race programmable rather than fixed to four.

Let$$s say the horses are initially in the order $1234.$ If you call Readysetgo to randomly shuffle them $($that$$s our pseudo$-$race$)$ we might get a race result of $2143$ for example, which means: horse #$2$ came in first, horses #$1$ came in second, horse #$4$ came in third and horse # $3$ came in fourth.

The user starts out with $200$ dollars. Betting costs are as follows:

Exacta bet costs $15$ dollars, you win $150$ if you win by picking both the first place horse and picking the second place horse exactly right

Exacta Box bet costing $10$ dollars, you win $100$ if you win by picking both the first place and second place horse and they can come in any order.

Trifecta bet costs $20$ dollars, you win $250$ if you win by picking the first place horse and picking the second place horse and picking the third place horse exactly right.

Trifecta Box bet costs $18$ dollars, you win $180$ if you win by picking the first place and second place and third place horse and they can come in any order.

Advanced students can $($but are not obligated to$)$ make this bet cost programmable, ie some students allow the user to decide how much they want to bet on the race, and some even let the user borrow money and get more in debt if they keep on losing and run out their $200$ dollars.

We need our program to allow the user to place any of the four types of bets. The user is given a USD $($US dollars$)$ cash balance of $200$ dollars for betting. The menu options allow the user to place any of the four bets, run the race, see the result, see what their cash balance is$,$ and exit the program. Advanced students if you wanted to $($but are not obligated to$)$ you could save a history of the bets they placed so they could also ask for their betting history.

There are two easy ways to implement the user interface for this, one is going to be with a simple text based menu, and one is going to be with a simple string$/$command$-$line based menu. A text menu is where you give the user a choice of options and tell them for example: enter $1$ to place an exactabet, enter $2$ to place an exactabox bet, etc. ie:

Welcome to Horse Betting!

Please select from the following options $1-6$

Place an exact bet

Place an exactabox bet

Place a trifectabet

Please a trifectabox bet

See your USD balance

Exit

etc

They then choose the option they want and then you ask them what horses they pick as the winners, get their pick, run the race, see if they won, etc.

A string based menu is a slightly different input style, where the input is more of a command$-$line driven sentence that gets parsed into components in the program to determine what they want, for example, if the user inputs the command line sentence

$>$ exacta $12$

the program will read that in$,$ divide that up into the components and figure out that they are placing an exacta bet with horse $1$ and $2$ as the picks. This involves splitting the input up $-$ if you think of the input as a sentence you will want to chop it up into words. I will give an example on how to do this in a google document called Split.

YOU SHOULD IMPLEMENT THIS WITH THE STRING BASED MENU USING THE STRING SPLIT. I am going to be giving a lecture on both approaches with examples of both, to show you how to make such a user interface. I am also going to cover relevant new material over several lectures and I will give many hints and working examples to the beginners to help them set all of this up to work. Let$$s talk about what the four bets mean $($I will also be showing you some intro horse betting videos to help you understand how exacta and trifecta betting works if you have never been to the racetrack$).$

Example Input:

EXACTA $13$

EXACTA $13$ means that we are betting that the winner and second place will be exactly in that order $($ie; the bet is betting
