class myDocument {
public:
myDocument(const char *docname);
~myDocument();
void print();
create an object for the above class that will opens a .txt file and remains open.
utilize method print() to output the text in the .txt file to the screen.
The constructor will be used to close the file. Lastly, if the file cannot be read, an exception must be thrown by the constructor.
ensure that function main() must provide and handles exceptions correctly.

Problem Write a C++ program that will simulate a Change Password Utility. Your program will contain: One class, PasswordManager, that will manage a single password for a given username. A driver containing a main function that will allow the user to change their password. PasswordManager Class The PasswordManager class should have two member variables (both strings): a username an encrypted password. Do not store the password (in the class or in a text file) unencrypted! The PasswordManager class should have the following two internal member functions (not accessible outside of the class): encrypt: this takes a password (a string) and returns the encrypted form of the password. Note: there is no decrypt function (there is no need to decrypt passwords). We will use the following VERY simple encryption algorithm (a Caesar Cipher): For every character in the input string, add 37 to the…Given the following definition of the classes Person, Father, and Home,which option, if used to replace/* INSERT CODE HERE */,will cause the code to compilesuccessfully (select 3 options):class Person {}class Father extends Person {public void dance() throws ClassCastException {}}class Home {public static void main(String args[]) {Person p = new Person();try {((Father)p).dance();}//INSERT CODE HERE}}Question options: catch (NullPointerException e) {}catch (ClassCastException e) {}catch (Exception e) {}catch (Throwable t) {} catch (ClassCastException e) {}catch (NullPointerException e) {}catch (Exception e) {}catch (Throwable t) {} catch (ClassCastException e) {}catch (Exception e) {}catch (NullPointerException e) {}catch (Throwable t) {} catch (Throwable t) {}catch (Exception e) {}catch (ClassCastException e) {}catch (NullPointerException e) {} finally {}

- Part 1: In C#, Create a Class Called FileRoot As we know, when we run a program, the program runs from the bin folder. If I had a file stored at the root of the project and if the program is running, it wouldn't know where it is unless it came out of the bin folder. Before implementing the classes below, create a class that will help you get from the bin folder to the project's root. Hint: Directory class and its static methods would help here.The provided file has syntax and/or logical errors. Determine the problem(s) and fix the program. Hint: You shouldn't have to add or delete any lines of code for Debugging 9-2. This one can be done by just editing the lines that are there. // Creates a Breakfast class // and instantiates an object // Displays Breakfast special information using System; using static System.Console; using System.Globalization; class DebugNine2 { staticvoidMain() { Breakfast special = new Breakfast("French toast, 4.99); //Display the info about breakfast WriteLine(INFO); // then display today's special WriteLine("Today we are having {1} for {1}", special.name, special.Price.ToString("C2", CultureInfo.GetCultureInfo("en-US"))); } } class Breakfast { public string INFO = "Breakfast is the most important meal of the day."; // Breakfast constructor requires a // name, e.g "French toast", and a price public Breakfast(string name, double price) { name = name; price = price; } public string Name {get; set}…Must be written in Python. Please include docstring and show how output should look like. Remember that all data members should be private. An object can access it's own private data members directly. It can also access the private data members of other objects of the same class directly. But when accessing a private data member of an object of another class, it needs to call the appropriate get method. If that sounds complicated, just remember this: if a method is in the same class as a private data member, then it can access that data member directly, otherwise, it needs to use a get method. Write a class named Point that has two data members, x_coord and y_coord, representing the two coordinates of the point. It should have: an init method that takes two arguments, an x-coordinate and y-coordinate (in that order), and uses them to initialize the two data members. get methods for the two data members: get_x_coord and get_y_coord. a method named distance_to that takes a Point object…
