- C++ We want to build an address book that is capable of storing name, address & phone number ofa person. Address book provides functionality in the form of a menu. The feature list includes: • Add – to add a new person record• Delete – to delete an existing person record by name• Search – to search a person record by name .. Sort - to sort the file after adding a new person record. · Exit – to exit from applicationin visual studio 2019 The GetCurrentDirectory method of Directory class is used to return the location of the current working directory (the location from which the program is running). true or falsePHONE DIRECTORYDescription: Create a phonebook directory that will store the contact numbers of N persons. Your program should allow the user to add, view, delete, and update the contacts in the phonebook. Note that one person can have multiple contact numbers. The program will stop when the user command is ‘X’. Program command and entry should not be case-sensitive. That means commands ‘I’ or ‘i’ and the name “Jacky” or “JACKY” are the same. Each contact number can be 7 digits or 11 digits only. The user should input a string containing the command, name, and contact number(s) (Limit the contact number of each person to three). This string should be broken down into fields in order to separate the different values and store them in their appropriate variables. Use linked list in the implementation. Your node must declare at least four instance variables. Program flow: Command> I Jacky 09211234567 Remarks: New contact has been added. Command> V Jacky Contact…
- Programming language: python3 Write a function that creates a new folder called “hw3-folder” inside the current directory (the one where your code is running).* The ofstream class then default mode of opening the file are ios::in ios::out O ios::outlios::trunk O ios::inlios::trunc OIn Chapter 11, you created the most recent version of the MarshallsRevenue program, which prompts the user for customer data for scheduled mural painting. Now, save all the entered data to a file that is closed when data entry is complete and then reopened and read in, allowing the user to view lists of customer orders for mural types.
- Create a program named FileComparison that compares two files. First, use a text editor such as Notepad to save your favorite movie quote. Next, copy the file contents, and paste them into a word-processing program such as Word. Then, write the file-comparison application that displays the sizes of the two files as well as the ratio of their sizes to each other. To discover a files size, you can create a System. 10. Filelnfo object using statements such as the following, where FILE_NAME is a string that contains the name of the file, and size has been declared as an integer: FileInfo fileInfo = new FileInfo(FILE_NAME); size = fileInfo.Length;Write the code in python Create an application that can create, display, search and maintain the book information for a bookstore. Requirements: 1) you need to use functions to write code for each menu item. 2) Information of books will be saved in a file, e.g,, books.txt. 3)User can add any number of books to the booklist. There can be 5 books or 500 books. In order for your program to handle it without any changes in the code, you cannot hardcode the number of books in your program.in C# Code in VS studio: Create a program that has 2 options for a user to select. The first option accepts information from the user and then save that data to a file on disk. The second option loads all data stored on that file.
