- Language: C++ Create a class called publication that stores the title (char array) and price (float) of a publication. From this class derive two classes: book, which adds a page count (int) and tape, which adds a playing time in minutes (float). Each of the three classes should have a getdata() function to get its data from the user using input from the keyboard and a putdata() function to display the data.Write a main function that creates an array of pointers to publication. In a loop, ask the user for data about a particular type of book or tape to hold data. Put the pointer to the object in the array. When the user has finished entering data for all the books and tapes, display the resulting data for all the books and tapes entered, using a for loop and a single statement such as: pubarr[j] -> putdata(); To display the data from each object in the array.Java OOP Write a complete address book maintenance application. The user of the program has four options: Add a new person, delete a person, modify the data of a person, and search for a person by giving the name. Use the AddressBook class, either the original one from the chapter or the modified one from the previous exercises. You have to decide how to allow the user to enter the values for a new person, display person information, and so forth.C++ Progrmaing Instructions Redo Programming Exercise 6 of Chapter 8 using dynamic arrays.

The first entry in the file contains answers to the test in the form: TFFTFFTTTTFFTFTFTFTT Every other entry in the file is the student ID, followed by a blank, followed by the student’s responses. For example, the entry: ABC54301 TFTFTFTT TFTFTFFTTFT indicates that the student ID is ABC54301 and the answer to question 1 is True, the answer to question 2 is False, and so on. This student did not answer question 9 (note the empty space). The exam has 20 questions, and the class has more than 150 students. Each correct answer is awarded two points, each wrong answer gets one point deducted, and no answer gets zero points. Write a program that processes the test data.

- C++ Struct Pointers Help: I have a file called names.txt. Write a program that reads each line and then store the name and nickname under an individual pointer to the class Person. names.txt: Norman, Normie Justine, Jussy Richard, Dick Shelley, Shell class Person { public: string name; string nickname; Person(string name, nickname) { this->name=name; this->nickname = nickname; } }; Print out each pointer's name and nickname to verify that it has been stored.Write JAVA code General Problem Description: It is desired to develop a directory application based on the use of a double-linked list data structure, in which students are kept in order according to their student number. In this context, write the Java codes that will meet the requirements given in detail below. Requirements: Create a class named Student to represent students. In the Student class; student number, name and surname and phone numbers for communication are kept. Student's multiple phones number (multiple mobile phones, home phones, etc.) so phone numbers information will be stored in an “ArrayList”. In the Student class; parameterless, taking all parameters and It is sufficient to have 3 constructor methods, including a copy constructor, get/set methods and toString.Using Classes Write a program that inputs, processes, and outputs a set of student records organized as a vector of class StudentRec objects. write a program where each student record is constructed using the class StudentRec. The variables in this case are "private" and the functions are "public." Note: only the first_name and last_name variables will require "getter" functions that return the name in all caps: get_first_name_upper() and get_last_name_upper() functions. Your class declaration section should look something like this: class StudentRec { private: string last_name = ""; // Last name string first_name = ""; // First name int year_grad = 0; // Year expected to graduate float gpa = 0.0; // Current gpa public: void set_last_name(string last_name_param); string get_last_name() const; string get_last_name_upper() const; // the rest of the "setter" and "getter" functions for each variable above go…
- 1- The FloatArray class stores a dynamic array of floats and its size. 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 array elements 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 to the 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 the array.4- The PositiveArray that inherits from SortedArray. It has:- A parameterized constructor…c++ Redo Programming Exercise 6 of Chapter 8 using dynamic arrays. The instructions have been posted for your convenience.

- CLASSES, DYNAMIC ARRAYS AND POINTERS Define a class called textLines that will be used to store a list of lines of text (each line can be specified as a string). Use a dynamic array to store the list. In addition, you should have a private data member that specifies the length of the list. Create a constructor that takes a file name as parameter, and fills up the list with lines from the file. Make sure that you set the dynamic array to expand large enough to hold all the lines from the file. Also, create a constructor that takes an integer parameter that sets the size of an empty list. in C++ Write member functions to: remove and return the last line from the list add a new line onto the end of the list, if there is room for it, otherwise print a message and expand the array empty the entire list return the number of lines still on the list take two lists and return one combined list (with no duplicates) copy constructor to support deep copying remember the destructor!Write every task in C++ programming language using arrays, array input/output and array operations. Task 1: Write a program that reads a text file which has a poem written in it. (Write down the poem yourself in a text file manually). Your program should display that poem and count total number of lines in the file. Task 2: Write a program that inputs the names of five cities from user in a string and stores/write them in a file city.txt Task 3: Write a program that reads the records stored in students.txt file and display them.Using Classes Write a program that inputs, processes, and outputs a set of student records organized as a vector of class StudentRec objects. Using the attached code as a "model", write a program where each student record is constructed using the class StudentRec. The variables in this case are "private" and the functions are "public." Note: only the first_name and last_name variables will require "getter" functions that return the name in all caps: get_first_name_upper() and get_last_name_upper() functions. Your class declaration section should look something like this: class StudentRec { private: string last_name = ""; // Last name string first_name = ""; // First name int year_grad = 0; // Year expected to graduate float gpa = 0.0; // Current gpa public: void set_last_name(string last_name_param); string get_last_name() const; string get_last_name_upper() const; // the rest of the "setter" and "getter"…
