Case Problems - 1- In Chapter 8, you modified the EventDemo program for Carly’s Catering to accept and display data for an array of three Event objects. Now, modify the program to use an array of eight Event objects. Prompt the user to choose an option to sort Events in ascending order by event number, number of guests, or event type. Display the sorted list, and continue to prompt the user for sorting options until the user enters a sentinel value. Save the file as EventDemo.java.
Create a structure called applianceTvpe with the following members. Use the proper variable TYPES for the members: name; SUpplierlD: modelNo: cost; Create an array variable of type applianceType that can hold 50 components. Write the code segment to read from a file into the structure array. Declare an input file stream identifier for this purpose. Open the file and read until end of file. Keep a count of how many rows actually read. The data file contains the following data: RefrigeratorABC 80 4657 521.62 ToasterOven 100 3245 245.96 MicroWave 95 7878 345.67 Using a looping construct, output to the console (cout) the data read into the structure array. Make sure you do not go outside the bounds of the array or beyond the number of rows actually read. You do not need to write any #include statements, using statements and you do not have to write code to open the file. Assume the file is open. You do need to declare variables needed for the program segment.
In Python Write a program that reads movie data from a CSV (comma separated values) file and output the data in a formatted table. The program first reads the name of the CSV file from the user. The program then reads the CSV file and outputs the contents according to the following requirements: Each row contains the title, rating, and all showtimes of a unique movie. A space is placed before and after each vertical separator ('|') in each row. Column 1 displays the movie titles and is left justified with a minimum of 44 characters. If the movie title has more than 44 characters, output the first 44 characters only. Column 2 displays the movie ratings and is right justified with a minimum of 5 characters. Column 3 displays all the showtimes of the same movie, separated by a space. Each row of the CSV file contains the showtime, title, and rating of a movie. Assume data of the same movie are grouped in consecutive rows. Ex: If the input of the program is: movies.csv and the contents…
Using the data file below design a hierarchical struct to organize the data. Then declare an array of structs for the reservations. The data file contains ten reservations. There are 8 columns of data: party name, size, date and time for the reservation, phone number, email address, credit card number and expiration date for the credit card. The data can be read from the file below so you will not need to type it in repeatedly. Once you have populated the array with data perform the following tasks: Write a function that will print out to the screen the information for one reservation.In the main program write code that prompts the user to enter a date in the form MM DD YYYYCall the function to print out all reservations on that date. You can make a loop that calls the print function repeatedly or you can put that code inside the print function.TEST CASES: April 30, 2023 and May 12, 2023. In this example you need to carefully consider what data types to use. For example, the credit…

In the student sample program files for this chapter, you will find a text file namedGasPrices.txt. The file contains the weekly average prices for a gallon of gas in the UnitedStates, beginning on April 5th, 1993, and ending on August 26th, 2013. Figure 8-7 shows anexample of the first few lines of the file’s contents:Figure 8-7 The GasPrices.txt fileDescriptionEach line in the file contains the average price for a gallon of gas on a specific date. Each line isformatted in the following way:MM-DD-YYYY:PriceMM is the two-digit month, DD is the two-digit day, and YYYY is the four-digit year. Price is theaverage price per gallon of gas on the specified date.For this assignment, you are to write one or more programs that read the contents of the file andperform the following calculations:Average Price Per Year: Calculate the average price of gas per year, for each year in thefile.

5. Charge Account Validation If you have downloaded the source code from the Computer Science Portal you will find a file named charge_accounts.txt in the Chapter 07 folder. This file has a list of a com- pany's valid charge account numbers. Each account number is a seven-digit number, such as 5658845. Programming Exercises 403 program Write a program that reads the contents of the file into a list. The program should then ask the user to enter a charge account number. The program should determine whether the number is valid by searching for it in the list. If the number is in the list, the should display a message indicating the number is valid. If the number is not in the list, the program should display a message indicating the number is invalid. (You can access the
