Abstraction is a key part of object-oriented programming and the concepts apply particularly well to classes. How would the same concepts apply to data structures and how we tend to define and think of ADTs?

Create an application that determines the total due on purchases including sales tax and shipping charges. Allow the user to input any number of item prices. Use a do-while loop such that in the first iteration, you ask the user to enter the price for an item. Keep a counter variable to track the number of items the user has entered by incrementing its value at every iteration. As the last statement for the do{} construct, ask the user if they wish to enter more item prices. Re-execute the do-while loop if the user enters “yes”.
Shipping charges are determined based on the number of items purchased using the following chart (if necessary, use if/else statements for making this decision).
Fewer than 3 items $3.50
3 to 6 items $5.00
7 to 10 items $7.00
11 to 15 items $9.00
More than 15 items $10.00
In addition to the above, if the total purchase (before adding sales tax) is $100.00 or more, then provide free shipping. If the user is $10.00 or less away from reaching a total purchase of $100.00, then display a message prompting the user that they are “that many” dollars away from free shipping. This should be implemented in a way that allows the user to continue entering items if they are close to free shipping.
Sales tax of 7.75% is charged against the total purchase. Display an itemized summary to the user with the following information. Total purchase charge, number of items purchased, sales tax amount, shipping charge, and the grand total. Use proper format specifiers if necessary.

LastNameFirstNameWeek4.java Purpose: This program will take an order on a local beverage parlor. This beverage parlor offers a limited set of drinks by a glass. Any day of the week (except Mondays when they are closed) they offer three possible alternatives: “Juice”, “Milk”, or “Soda”. Additionally only Fridays, Saturdays and Sundays, the beverage parlor serve also “Beer” and “Wine”. The program should ask the users for her/his beverage choices and produce a summary of the order in the end. To do so, the program will initially get the name of a day in a week (Monday, Tuesday, Wednesday, etc.) from the user. If the day is Monday, the program should print “Sorry. This establishment is closed on Mondays. Your order includes nothing.” And the program will stop. If the day is Tuesday, Wednesday or Thursday, the program will ask the user: “Which beverages would you like to drink?: juice, milk, or soda?" and receive the answer. If the day is Friday, Saturday or Sunday, the program would ask to the user: "Which beverages would you like to drink?: juice, milk, soda, beer, or wine?" and get an answer. After every new beverage order, the program will ask if the user wants to order something else. If the user wants to order something else, the requesting process is repeated within a loop, but the day given at the beginning of the session will remain. Every time the user selects one of the beverages, a corresponding counter for each of these meals should be updated (adding 1 to it). When the user indicates s/he does not want to order more, the program will print the total order with the correct count of each beverage that was ordered and stop. If a beverage was not ordered, its name must not appear in the final list. Notice that responses from the user may be entered in any combination of uppercase or lowercase letters. The best will be to read all responses using the next() method of the Scanner, convert these responses to uppercase letters with the toUpperCase() method of the String class, and use this uppercase version of the response to do comparisons with the choices (also in upper case). Your output should be similar to the samples shown below. Do not change the order of the questions neither the messages that are displayed. Sample 1 Which day are you visiting the Restaurant (Monday, Tuesday, Wednesday, etc.)?Tuesday Which beverages would you like to drink?: juice, milk, or soda?milk Do you want to add anything else to the order?

First, the Python program prompts user to enter user information (name, email, and phone number). Then it displays a menu called “Fish Information” that has the following fish type:
1. Cat Fish 2. Red Fish 3. Any other fish
Let user choose the fish type that he/she got and input the length of the fish. Then the program will determine what should be done with this particular fish. Based on the following criteria:
Criteria: Length:
FISHTYPE - Cat Fish <10: "throw back" >=10 through <=25: "keep" >25: "tag"
FISHTYPE – Red Fish <15: "throw back" >=15 through <=30: "keep" >30: "tag"
FISHTYPE – any other fish <10: "throw back" >=20: "keep"
Let the user to enter as many times they want using loops and save all the input data using List.
At the end, the program will display the user’s information and all the fish information.

A company has three salespeople (1 to 3) who sell five different products (1 to 5). Once a day, each saleperson passes in a slip for each type of product sold. Each slip contains the following: a) The salesperson number b) The product number c) The total dollar value of that product sold that day Thus, each salesperson passes in between 0 and 5 sales slips per day. Assume that the information from all of the slips for last month is available. You are required to write a C# program that will read all the information for last month’s sales and summarize the total sales by salesperson and by product. All sales data should be stored in a two-dimensional array sales. After processing all the information for last month, display the results in tabular format, with each column representing a particular salesperson and each row representing a particular product. Cross-total each row to get the total sales of each product for last month. Cross-total each column to get the total sales by salesperson for last month. You tabular output should include these cross-totals to the right of the totaled rows and below the totaled columns.
A sample output is as follows:
Enter sales person number (-1 to end): 1
Enter product number: 100
Enter sales amount: 1000
Invalid input!
Enter sales person number (-1 to end): 1

Write a program that will write the contents of a text file backwards one character at a time. Your program should first ask for the text file name to be processed – and after verifying that the file exists, it should read the file into a StringBuilder buffer. Save the new file using the old filename appended with “Ver2-“ at the front. So for the file “MyStuff.txt” the file would be saved as Ver2-MyStuff.txt”. You can use any text file to test your work.
