- Create an Organization class. Organization has 10 Employees (Hint: You will need an array of pointers to Employee class) Organization can calculate the total amount to be paid to all employees Organization can print the details(name & salary) of all employees note: write code in main,header and function.cpp file*python coding please This exercise assumes that you have created the Employee class for Programming Question 1.Create a program that stores Employee objects in a dictionary. Use the employee ID numberas the key. The program should present a menu that lets the user perform the following actions:• Look up an employee in the dictionary• Add a new employee to the dictionary• Change an existing employee’s name, department, and job title in the dictionary• Delete an employee from the dictionary• Quit the programWhen the program ends, it should pickle the dictionary and save it to a file. Each time theprogram starts, it should try to load the pickled dictionary from the file. If the file does notexist, the program should start with an empty dictionaryC# According to the following statement, __.Random rn = new Random(); Question 1 options: It declares a variable named rn that can be used to reference an object of the Random type. The new operator creates an object in memory and returns a reference to that object. The = operator assigns the reference that was returned from the new operator to the rn object. All of the above.
- Book Donation App Create a book-app directory. The app can be used to manage book donations and track donors and books. The catalog is implemented using the following classes: 1. The app should have donors-repo.js to maintain the list of donors and allow adding, updating, and deleting donors. The donor object has donorID, firstName, lastName, and email properties. This module should implement the following functions: • getDonor(donorId): returns a donor by id. • addDonor(donor): adds a donor to the list of donors; donorID should be autoassigned a random number. • updateDonor(donor): updates the donor having the matching donorID. • deleteDonor(donorID): delete the donor with donorID from the list of donors, only if they are not associated with any books. 2. The app should have books-repo.js to maintain the list of donated books and allow adding, updating, and deleting books. The book object has bookID, title, authors, and donorID properties. • donorID references the book’s donor. This…Computer Science Write the code to define a class called student. The student class should contain a data attribute called name and another attribute called gpa. Write the Student class to include an initializer method __init__ and a __str__ method. Create two different objects of the student class and call print on each object to display the output in the __str__method.(Querying an Array of Invoice Objects) Use the class Invoice provided in the lab assignment to create an array of Invoice objects.Class Invoice includes four properties—a PartNumber (type int), a PartDescription (type string), a Quantity of the item being purchased (type int) and a Price (type decimal).Write a console application that performs the following queries on the array of Invoice objects and displays the results:a) Use LINQ to sort the Invoice objects by PartDescription.b) Use LINQ to sort the Invoice objects by Price.c) Use LINQ to select the PartDescription and Quantity and sort the results by Quantity.d) Use LINQ to select from each Invoice the PartDescription and the value of the Invoice(i.e., Quantity * Price). Name the calculated column InvoiceTotal. Order the results by Invoice value. [Hint: Use let to store the result of Quantity * Price in a new range variable total.]e) Using the results of the LINQ query in Part d, select the InvoiceTotals in the range$200 to…
- To make use of a virtual function in numerous ways, an application may utilise base class pointers or references to activate a virtual function.Flowchart for student interface program please. Create a program to enter grades and calculate averages and letter grades. Need a class which will contain: Student Name Student Id Student Grades (an array of 3 grades) A constructor that clears the student data (use -1 for unset grades) Get functions for items a, b, and c, average, and letter grade Set functions for items a, n, and c Note that the get and set functions for Student grades need an argument for the grade index. Need another class which will contain: An Array of Students (1 above) A count of number of students in use You need to create a menu interface that allows you to: Add new students Enter test grades Display all the students with their names, ids, test grades, average, and letter grade Exit the program Add comments and use proper indentation. Nice Features: I would like that system to accept a student with no grades, then later add one or more grades, and when all grades are entered, calculate the final…Bank ProgramThis c++ assignment uses the same account class created in Lab #4 with a more generally useful interface.

Valid account numbers are 1-9. This requires the program to have an array of references to Account objects.2. If the first word on any line contains a command other than the four listed above, an error message should be displayed and that line ignored.3. The create command creates a new account object with the given account number and initial balance. If an account already exists with that number an error message should be displayed and the command ignored.4. The Deposit and Withdraw commands perform the indicated operation on an existing account. If no account with that number…
- Given main(), create the Calculator struct that emulates basic functions of a calculator: add, subtract, multiple, divide, and clear.
