- 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.A pointer is basically a reference to an object or a function. In fact, it is a variable that holds memory address. This address is the location of some other variable or object in memory. For example, if one variable contains the address of another variable, first one is said to point to the second one. Pointers may have many uses, such as to make functions implement “call-by-reference" methodology and to construct dynamic arrays or structures at run-time. Write a complete C program that implements below given user-defined function prototypes for arrays-of-integers. * void input_ld_array( int*, int ); void output_ld_array( int*, int ); int sum_ld_array( int*, int ); * float average_ld_array( int*, int ); v Test each function separately!In C programming: Write a main() function using the following requirements:• Define a SIZE constant (the value is irrelevant, but for testing, you may want to keep it small enough – no bigger than 5)• Create an array of course pointers using SIZE• Dynamically allocate each element of the array• Call inputAllCourses()• Call printAllCourses().

- Python only** define the following function: 1. This function must add a task to a checklist, setting its initial value to False. It will accept two parameters: the checklist object to add to, and the task name to add. In addition to adding the task, it must return the (now modified) checklist object that it was given. There is one issue, however: a task cannot be added to a checklist if the name requested is already being used by another task in that checklist. In that case, this function must print a specific message and must return None Define addTask with 2 parameters Use def to define addTask with 2 parameters Use a return statement Within the definition of addTask with 2 parameters, use return _ in at least one place. Do not use any kind of loop Within the definition of addTask with 2 parameters, do not use any kind of loop.Write a c++ program with a class that contains following data members Id name marks Create array of objects of size 10. Create a function read() to take input from user. Create a function to calculate percentage of each student and a function that displays the id and name of the student that have the lowest percentage.A pointer is basically a reference to an object or a function.

- Describe how pointers work with functions as parameters and functions as return values.Write in C++ 1. Define a struct for a soccer player that stores their name, jersey number, and total points scored. 2.Using the struct in #1, write a function that takes an array of soccer players and its size as arguments and returns the average number of points scored by the players. 3.Using the struct in #1, write a function that takes an array of soccer players and its size as arguments and returns the index of the player who scored the most points. 4.Using the struct in #1, write a function that sorts an array of soccer players by name. 5.Using the struct in #1, write a function that takes an (unsorted) array of soccer players and its size and a number as arguments, and returns the name of the soccer player with that number. It should not do any extra unnecessary work. 6.Define a function to find a given target value in an array, but use pointer notation rather than array notation whenever possible. 7.Write a swap function, that swaps the values of two variables in main, but use…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.
