Create a CashRegister class that can be used with the Retail Item class. The CashRegister class should be able to internally keep a list of Retail Item objects. The class should have the following methods: • A method named purchase_item that accepts a Retail Item object as an argument. Each time the purchase_item method is called, the Retail Item object that is passed as an argument should be added to the list. ● A method named get_total that returns the total price of all the Retail Item objects stored in the CashRegister object's internal list. A method named show_items that displays data about the Retail Item objects stored in the CashRegister object's internal list. • A method named clear that should clear the CashRegister object's internal list. Demonstrate the Cash Register class in a program that allows the user to select several items for purchase. When the user is ready to check out, the program should display a list of all the items he or she has selected for purchase, as well as the total price.

Searching - a user should be able to search by ID or by item name create only one menu item for searching a user should be able to enter the name of the item using any case, (for example, sTRolleR) you may wish to store items in all lower/upper case to expedite the search write one search function that can search by ID and name and goes through the array of structs/objects only once show the entire record if found or an appropriate message if not Sorting - sort by any field write one function to sort by any field using a parallel array of pointers use Bubble Sort is not the most effective but the easiest to modify. do not copy and paste sort code five times into the same function. sorting using pointers is faster because you have to swap pointers only, which are normally stored in 4 bytes each; it also allows you to preserve the original order of the items If you choose to have a submenu, a submenu must have an option to go back to the previous menu or main menu if a user got…
Python Programming Assignment: Create a dictionary that takes a basketball team's information (that includes team's name and points) as parameter, creates a teams_dict and returns it. Also, create a parameter for write_file parameter that opens current results text file in write mode and writes the dictionary information to file as per format and closes the file.
8. Name and Email Addresses Write a program that keeps names and email addresses in a dictionary as key-value pairs. The program should display a menu that lets the user look up a person’s email address, add a new name and email address, change an existing email address, and delete an existing name and email address. The program should pickle the dictionary and save it to a file when the user exits the program. Each time the program starts, it should retrieve the dictionary from the file and unpickle it.
Computer Science JAVASCRIPT .xlsx parser I need to write a public class that reads an .xlsx file and returns an array of data in javascript. The array would be all of the data inside of the file. The file itself is going to be inside of a folder(downloadedFIles) inside of my project. So the public class will need to account for that.
Word FrequencyWrite a python program that reads the contents of a text file. The program should create a dictio-nary inwhich the keys are the individual words found in the file and the values are the number of timeseach word appears. For example, if the word “the” appears 128 times, the dictionary wouldcontain an element with 'the' as the key and 128 as the value. The program should eitherdisplay the frequency of each word or create a second file containing a list of each word and itsfrequency.
createDatabaseOfProfiles(String filename) This method creates and populates the database array with the profiles from the input file (profile.txt) filename parameter. Each profile includes a persons' name and two DNA sequences. 1. Reads the number of profiles from the input file AND create the database array to hold that number profiles. 2. Reads the profiles from the input file. 3. For each person in the file 1. creates a Profile object with the information from file (see input file format below). 2. insert the newly created profile into the next position in the database array (instance variable).

Program Specification For this assignment you will write a program to help people record the events of their day by supplying prompts and then saving their responses along with the question and the date to a file. Functional Requirements This program must contain the following features: Write a new entry - Show the user a random prompt (from a list that you create), and save their response, the prompt, and the date as an Entry. Display the journal - Iterate through all entries in the journal and display them to the screen. Save the journal to a file - Prompt the user for a filename and then save the current journal (the complete list of entries) to that file location. Load the journal from a file - Prompt the user for a filename and then load the journal (a complete list of entries) from that file. This should replace any entries currently stored the journal. Provide a menu that allows the user choose these options Your list of prompts must contain at least five different prompts.…
Phyton: Program 6: Write a program that allows the user to add data from files or by hand. The user may add more data whenever they want. The print also allows the user to display the data and to print the statistics. The data is store in a list. It’s easier if you make the list global so that other functions can access it. You should have the following functions: · add_from_file() – prompts the user for a file and add the data from it. · add_by_hand() – prompts the user to enter data until user type a negative number. · print_stats() – print the stats (min, max, mean, sum). You may use the built-in functions. Handling errors such as whether the input file exist is extra credit. To print a 10-column table, you can use the code below: for i in range(len(data)): print(f"{data[i]:3}", end="") if (i+1)%10==0: print() print() Sample run: Choose an action 1) add data from a file 2) add data by hand 3) print stats 4)…
