- Write a class named Library. A library has the following attributes:• name: the name of this library.• employees: a list of LibraryEmployees that work at the library.• books: a dictionary that contains Books as keys. The value paired with each key is either anempty string, or a string representing the name of a person who has checked out the Book.The Library class should have an initializer that MAY accept employees and books as arguments,but doesn’t have to do so. If provided, these values should be assigned to the object’srespective attributes. If not provided, employees and books should begin as an empty list anddictionary, respectively. The value for the name attribute is always provided.The class should also have the following methods:• hire_employee(): takes in a new LibraryEmployee, and adds it to this library’s list ofemployees.• add_book(): takes in a new Book, and adds it to this library’s books (unless the libraryalready has this book). If the library already has the book,…arrow_forwardC++ PROGRAM Create a class MyClass with a string data member ‘paragraph’. Provide a constructor, getParagraph() and display() method in the class. getParagraph() method must read a paragraph from a file. The display method should display that paragraph. Create another class, MyFriendClass and make it a friend of the class MyClass. Provide a function getWord(MyClass &obj1, int index) with return type string in the class MyFriendClass which accepts an object of class MyClass (by reference) and an integer. The getWord() function should return the word at location index passed as an argument to the data member ‘paragraph’ of the object received as input.arrow_forwardProblem 2: Route Planning You are on the development team for a Route Planning application. The team has already developed a class named NavigatorApp for storing and displaying the graph representing the road network. This class has a void displayShortestPath() function which takes the source and destination vertices of the trip and displays the shortest route between them. Using the strategy pattern, draw a class diagram of the system which will allow for the NavigatorApp to display the shortest driving, walking, or cycling route when the displayShortestPath() function is called. You can assume that another developer is in charge of making sure the appropriate strategy is correctly set and for calling the displayShortestPath() function Starter code /* Modify NavigatorApp (if necessary) */ class NavigatorApp { private: Graph map; public: void displayMap(Window * window); void displayShortestPath(Vertex source, Vertex destination, Window * window); /* write pseudo code for this function…arrow_forward
- array of Payroll ObjectsDesign a PayRoll class that has data members for an employee’shourly pay rate and number of hours worked. Write a program withan array of seven PayRoll objects. The program should read thenumber of hours each employee worked and their hourly pay ratefrom a file and call class functions to store this information in theappropriate objects. It should then call a class function, once foreach object, to return the employee’s gross pay, so this informationcan be displayed.arrow_forwardProcedure: Develop an extension of structure.Vector, called MyVector, that includes a new method, sort. Here are some steps toward implementing this new class: 1. Create a new class, MyVector, which is declared to be an extension of the structure.Vector class. You should write a default constructor for this class that simply calls super();. This will force the structure.Vector constructor to be called. This, in turn, will initialize the protected fields of the Vector class. 2. Construct a new Vector method called sort. It should have the following declaration: public void sort(Comparator c) // pre: c is a valid comparator // post: sorts this vector in order determined by c This method uses a Comparator type object to actually perform a sort of the values in MyVector. You may use any sort that you like. 3. Write an application that reads in a data file with several fields, and, dependingarrow_forward(Rectangle Class) Create a class Rectangle with attributes length and width, each of whichdefaults to 1. Provide member functions that calculate the perimeter and the area of the rectangle.Also, provide set and get functions for the length and width attributes. The set functions should verify that length and width are each floating-point numbers larger than 0.0 and less than 20.0.arrow_forward
- C# Write a console app that sets up a dictionary of Books in a Library. The dictionary is indexed by ISBN. Each bookstored in the dictionary is a Book object that stores Title and Author. The Book class should be a simple entityclass containing the Title, Author, and ISBN.arrow_forwardStatic analyzer write code c++ create your static analyzer tool thatreads your code as a text. Then, it analyzes it based on the below checklist. The checklist: - Do the attributes (e.g., data type and size) of each parameter match theattributes of each corresponding argument?arrow_forwardUsing C++ to Creates a class called Member with two integer x and y. a. Add a constructor able to create a Member object with tow integers and the default values 0,0; b. Add the methods setX and setY to modify the attributes x and y; c. Add the method display able to display the attributes, - A Queue is a special array where the insertion and deletion will be via a specific index called "head". A Queue is characterized by 3 attributes: a. capacity (int): the maximum number element Member that can be contained into the Queue; b. head: presents the index where we can add/remove element to the Queue. The head value presents also the current number of elements into the Queue. When a Queue is created the initial value of head is 0; c. Member content[]: an array of elements of type Member; Creates the class Queue with the following methods: a. a Constructor able to create a Queue with maximum 10 Members; b. bool empty (): this method returns true if no element exists in the Queue c. bool…arrow_forward
- Network Class The Network class represents a network of people that are connected to each other and are able to contact and send messages to each other through the network. Create a Network class with the following: Member Variables A Network has just one private member variable: phonebook_ - a std::map which maps from a std::string for a person's name, to the std::shared_ptr<Phone> object that belongs to that person. Constructor You do not need to explicitly define a constructor. The default constructor will implicitly be created for us by the compiler, initializing the phonebook_ to an empty map. AddPhone Create a function AddPhone that accepts a std::shared_ptr to a Phone and inserts that Phone to the phonebook_. The key is the name of that phone's owner, and the value is the shared pointer to the Phone. SendMessage Create a function SendMessage that accepts a std::shared_ptr to a Message and a const reference to a std::string representing the intended recipient of this…arrow_forwardInstructions: Turn all instances of classes into pointers. You will also need to combine the player and vector into one vector objects and fix all issues this causes. #ifndef ITEM_H #define ITEM_H class Item { public: Item() {}; enum class Type { sword, armor, shield, numTypes }; Item(Type classification, int bonusValue); Type getClassification() const; int getBonusValue() const; private: Type classification{ Type::numTypes }; int bonusValue{ 0 }; }; std::ostream& operator<< (std::ostream& o, const Item& src); bool operator< (const Item& srcL, const Item& srcR); int& operator+=(int& srcL, const Item& srcR); #endif // !ITEM_H #ifndef MONSTER_H #define MONSTER_H #include "Object.h" class Player; class Monster : public Object { public: Monster() {}; Monster(const Player& player); void update(Player& player, std::vector& monsters) override; int attack() const override; void defend(int damage) override; void print(std::ostream& o)…arrow_forwardc++ Create a class Employee that shall have multiple attributes i.e., name, salary, experience,designation. The class shall have setter and getter function for each attribute. An array issupposed to be declared of type Employee which will have multiple employee type elements.The following operations are supposed to be performeda. Input information of each employee.b. Prints the information of the employee with the highest salary.c. Print the information of the employee with least experience.arrow_forward
