1.18 LAB: Input and formatted output: House real estate summary Sites like Zillow get input about house prices from a database and provide nice summaries for readers. Write a program with two inputs, current price and last month's price (both integers). Then, output a summary listing the price, the change since last month, and the estimated monthly mortgage computed as (currentPrice * 0.051) / 12. End the last output with a newline. Ex: If the input is: 200000 210000 the output is: This house is $200000. The change is $-10000 since last month. The estimated monthly mortgage is $850. Note: Getting the precise spacing, punctuation, and newlines exactly right is a key point of this assignment. Such precision is an important part of programming. 472578.3337676.qx3zqy7

Q1. The last post didnt include the items in the database. Need a different function for the python program display_ticket below: def display_tickets():t = Texttable()tickets=cur.execute('''SELECT * FROM tickets''')for i in tickets:t.add_rows([['tid', 'actual_speed','posted_speed','age','violator_sex'],list(i)])print()print(t.draw())print() Q2. Also need a different function for the python program add_ticket below: def add_tickets():actual_speed=int(input("enter actual speed:"))posted_speed=int(input("enter posted speed:"))age=int(input("enter age:"))sex=input("Male or Female:")cur.execute('''INSERT INTO tickets(actual_speed,posted_speed,age,violator_sex) VALUES(?,?,?,?)''',(actual_speed,posted_speed,age,sex))con.commit() If you'd like to see what thousands of traffic tickets look like, check out this link: https://www.twincities.com/2017/08/11/we-analyzed-224915-minnesota-speeding-tickets-see-what-we-learned/
For this assignment you are requested to write a program for the following scenario: • Build a program for a market, in the market we have items and each contains of three values (Item Name, Item Price, Item Expire Date). • The item values comes from a file each specification of the item is separated by (: ). • Must put the products that comes form the file into an array of object. • The program must check each product expire date if there is any products that expires in one month should notify the user as the output. • The expire checker process must be done on the array of object not directly from the file. NOTE: you can add only the month of the expiration date instead of adding full date (coffee:5000:August) and you can enter April as current month and then check the expiration.
Assume you have a folders of (images and videos) in your computer which contain some random mix numerical values. Your task is to separate images (e.g odd values) and videos (e.g Even values). So that all the images and videos are stored in separate folders (lists). While separating make sure that any of the folder (lists) should not contain any duplicate file or duplicate value. In this task images and videos odd & even numbers and folder means a single list of mix value. e.g: linkedlists (odd, even). Design a method for above task which will create two separate linked lists and write main method to test your program. FOLDER (VIDEO AND IMAGES:ODD AND EVEN VALUES) LIST 0: [2, 44 , 24 , 82 , 33 , 44 , 55 , 11 , 2 , 44 , 55]: EVEN VALUES_LIST 1: [2, 44 , 24 , 82]: A=2, B=44, C=24, D=82 ODD VALUES:_LIST 2: [33 , 44 , 55 , 11]: A=33, B=45, C=55, D=11
You are going to write a program (In Python) called BankApp to simulate a banking application.The information needed for this project are stored in a text file. Those are:usernames, passwords, and balances.Your program should read username, passwords, and balances for each customer, andstore them into three lists.userName (string), passWord(string), balances(float)The txt file with information is provided as UserInformtion.txtExample: This will demonstrate if file only contains information of 3 customers. Youcould add more users into the file.userName passWord Balance========================Mike sorat1237# 350Jane para432@4 400Steve asora8731% 500 When a user runs your program, it should ask for the username and passwordfirst.

1. Create a UML using the UML Template attached. 2. In this lab, you will be creating a roulette wheel. The pockets are numbered from 0 to 36. The colors of the pockets are as follows: Pocket 0 is green. For pockets 1 through 10, the odd-numbered pockets are red and the even-numbered pockets are black. For pockets 11 through 18, the odd-numbered pockets are black and the even-numbered pockets are red. For pockets 19 through 28, the odd-numbered pockets are red and the even-numbered pockets are black. For pockets 29 through 36, the odd-numbered pockets are black and the even-numbered pockets are red. Create a class named RoulettePocket. The class's constructor should accept a pocket number. The class should have a method named getPocketColor that returns the pocket's color, as a string. Demonstrate the class in a program that asks the user to enter a pocket number, and displays whether the pocket is green, red, or black. The program should display an error message if the user…
19. Write a recursive (no "while" or "for" or any looping statement) method "frequency", which takes as parameters an IntNode myList and an integer element and returns the number of times the integer element appears in myList. public class IntNode. { private int m_data; private IntNode m link; public IntNode (int data, IntNode link) { m data data; m link link; } public int getInfo() {return m_data; } public IntNode getLink () {return m_link; } } public int frequency (IntNode myList, int element) {
Write a program in C++ that reads a list of enrollments from a file and prints a class roster for the teacher. The program would use files, functions, and classes.Here's what the output should look like: $ ./enroll.out Welcome to the Roster Generator Program!!!

17. Create a class ShuffleCipher that implements the interface MessageEncoder, as described in Exercise 15. The constructor should have one parameter called n. Define the method encode so that the message is shuffled n times. To perform one shuffle, split the message in half and then take characters from each half alternately. For example, if the message is abcdefghi, the halves are abcde and fghi. The shuffled message is afbgchdie. (Hint: You may wish to define a private method that performs one shuffle.)
/*TASK 5. Implement part 1 of the report. You need to read data from input.txt file, store it into array of items (called items) and write it in a formatted form to the output file. Code, debug and present it in the best possible format. Hint: It might be helpful to format the String coming from toString( ) method using String.format( ) method, which works similar to System.out.prinf. Hint2: You might have to close and delete existing output .doc or .txt file from its folder * public class YourUserName_hw7 { static Item [ ] items = new Item [200];//an array of Items static EdibleItem [ ] edibleItems;//an array of Edible Items static int countEdibleitems = 0;//count edible items static String pageHeader; //save the header //main( ) method runs the program public static void main(String[ ] args) throws FileNotFoundException { double sum = 0, average = 0; //Optional - create a new input file //CreateInput.createInputFile( );…

Write a program that reads a list of enrollments from a file and prints a class roster for the teacher. Make the class roster line up as neatly as you can and still fit on the screen. You can choose the actual values to use for your data. Make sure to do enough sets of data to well test your program! (Empty data set, normal data set, data with large values, data with short values, etc.) Also, your program can't know ahead of time how many people are enrolled in the class... Don't forget to read the file's name from the user and protect your program against any errors that may occur during the opening of the file. Try to use functions to break up the program into more manageable pieces. USING C++ As an example, you might have the data file contain:
