Chapter 6, Problem 10PP
Write a program that will record the votes for one of two candidates by using the class VoteRecorder, which you will design and create. Vote Recorder will have static variables to keep track of the total votes for candidates and instance variables to keep track of the votes made by a single person. It will have the following attributes.
- nameCandidatePresident11—a static String that holds the name of the first candidate for president
- nameCandidatePresident2—a static string that holds the name of the second candidate for president
- nameCandidateVicePresident1 —a static string that holds the name of the first candidate for Vice president
- nameCandidateVicePresident2—a static string that holds the name of the second candidate for Vice president
- votesCondidatePresident1—a static integer that holds the number of votes for the first candidate for president
- votesCandidatePresident2—a static integer that holds the number of voles for the second candidate for president
- votesCandidateVicePresident1—a static integer that holds the number of votes for the first candidate for Vice president
- votesCandidateVicePresident2—a static integer that holds the number of rates for the second candidate for Vice president
- myVoteForPresident—an integer that holds the vote of a single individual for president (0 for no choice, 1 for the first candidate, and 2 for the second candidate)
- myVoteForVicePresident—an integer that holds the vote of a single individual for vice president (0 for no choice, 1 for the first candidate, and 2 for the second candidate)
In addition to appropriate constructors, VotRecorder has the following methods:
- setCandidaterPresident(String name1, String name2)—a static method that sets the names of the names of the two candidates for president
- getCandicateoVicePresident (String name1, string name2)—a static method that sets the names of the two candidates for vice president
- resetVotes—a static method that resets the vote counts to zero
- getCurrentVotePresident—a static method that returns a string with a current total number of votes for both presidential candidates
- getAndConfirmVotes—a non-static method that gets an individual’s votes, confirms then, and then records them
- getAVote(String name1, string name2)—a private method that returns a vote choice for a single race from a individual (0 for no choice, 1 for the first candidate, and 2 for the second candidate)
- getVotes—a private method that returns a vote choice for president and vice president from an individual
- confirmVotes—a private method that displays a person’s vote for president and vice president, asks whether the voter is happy with these choices, and returns true or false according to a yes-or-no response
- recordVotes—a private method that will add an individual’s votes to the appropriate static variables
Create a program that will candidates an election. The candidates for president are Annie and Bob. The candidates for vice president are John and Susan. Use a loop to record the votes of many voters. Create a new Vote Recorder object for each voter. After all the voters are done, present the results.

The __str__ method of the Bank class (in bank.py) returns a string containing the accounts in random order. Design and implement a change that causes the accounts to be placed in the string in ascending order of name.
Implement the __str__ method of the bank class so that it sorts the account values before printing them to the console.
In order to sort the account values you will need to define the __eq__ and __lt__ methods in the SavingsAccount class (in savingsaccount.py).
The __eq__ method should return True if the account names are equal during a comparison, False otherwise.
The __lt__ method should return True if the name of one account is less than the name of another, False otherwise.

- In python Add the following four methods to your Crew class: move(self, location): This takes in a location as a string, along with self, and attempts to move the crew member to the specified location. If location is one of the five valid location options ("Bridge", "Medbay", "Engine", "Lasers", or "Sleep Pods"), then this should change self.location to that new value. Otherwise, the function should print out the message: Not a valid location. repair(self, ship): first_aid(self, ship): fire_lasers(self, ship, target_ship, target_location): The above three methods represent tasks that a basic Crew member is not capable of (but one of its derived classes will be able to accomplish). So each of them should simply print out a message of the form: <Name> doesn't know how to do that.

The slot machine then displays a set of random images. If two or more of the images match, the user wins an amount of money, which the slot machine dispenses back to the user. Design a program that simulates a slot machine. When the program runs, it should do the following: Ask the user to enter the amount of money he or she wants to insert into the slot machine. Create an application that simulates a slot machine. The application should let the user enter into a TextBox the amount of money he or she is inserting into the machine. When the user clicks the Spin button, the application should display three randomly selected symbols. (Slot machines traditionally display fruit symbols.arrow_forward

The purpose of an object of this class is to store a string variable (you may use the C++ string type or a char array). An object of this class can be created by calling a constructor that accepts one string argument. The string to be passed as argument will be a long line of text, such as “The world is indeed full of peril and in it there are many dark places. But still there is much that is fair. And though in all lands, love is now mingled with grief, it still grows, perhaps, the greater.” The object will also have a function called printRightAligned() which accepts one integer argument n. The value of the argument represents the maximum number of characters that can be displayed on a line. This function displays the string stored in the object’s attribute on the screen, right aligned and with no more than n characters per line.

The constructor will only take in one parameter, a string representing the name of a CSV file. The file will have the following format: Each row will always have exactly two columns. The first row will always contain the name of the race. The second row will always contain the id number for the race. The third row will always contain the distance for the race.
