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,…

TaskDeclare and implement 5 classes: FloatArray, SortedArray,FrontArray, PositiveArray & NegativeArray.1- The FloatArray class stores a dynamic array of floats and itssize. It has:- A parameterized constructor that takes the array size.- An add method that adds a float at the end of the array.- Overloading for the insertion operator << to write the array to afile (ofstream)- Overloading for the extraction operator >> to read the arrayelements from the file (ifstream) and add them to the array.- A destructor to deallocate the array2- The SortedArray inherits from FloatArray. It has:- A parameterized constructor that takes the array size.- An add method that adds a float at the right place in the arraysuch that the array remains sorted with every add. Don’t add tothe array then sort but rather add in the right place.3- The FrontArray inherits from FloatArray. It has:- A parameterized constructor that takes the array size.- An add method that adds a float at the front of…
