- C++ Create a class Student that contains three members: roll no, name and mark, and three functions. Write a first inputStudent() function to get data of student class. Write a second getMark() function that returns a student’s mark. Write a third display() function that displays a student’s data. In a main() function, you need to declare 40 students and get data of all students by using inputStudent() function. And also use a pointer array to keep all students by mark greater than 50 and display the searching data of each student in that pointer array (Use the access operator -> to access a pointer points to member functions of the Student class).Research assistants provide support to professionals who are conducting experiments or gathering andanalyzing information and data. Suppose you are working as RA (research assistant) with a Professor who isworking on a project and evaluating complex mathematical equations. Your duty is to assist him, so in thisregard he has assigned a task to you. Your task is to write a oop c++ program to create a class named equation which will have the data members a, b and c which are the coefficients of the quadratic equation. The class will have two more data members namely proot and nroot which stand for the positive root and negative root of the equation. Suppose that variables a, b and c are integers. Where proot and nroot are floats. Input Function to get values of a, b and c Then design a friend function which will determine the proot and nroot of the equation. Create another friend function which will display the values of proot and nroot.Write a code for OOP based game in which a player (human) will play against computer, and the player to score 100 points first, will win the game. Follow these steps to complete your code. Create a class named game, with score as its private data • Define a function which will generate random numbers between 1 and 10 and store it to private data of the class and will add it to previous score • Another function will display the scores after each turn and if the score is 100 or more then declare the player (who scored 100 in less attempts) as a winner Create two objects in the main program named as player and computer • Player will press a specific key to play in his turn • The computer's turn will be executed after the player's turn • Keep on doing this until one of them scores 100 points To generate the random numbers the following two lines must be there srand (time (0)); // to make sure that different number is generated in each turn rand (); // it will generate random numbers You…
- programming language :c++ make a program in c++ to store hiring date and date of birth for Managers and Employees. You need to create a Date class for this purpose. Create objects of Date class in Manager and Employee classes to store respective dates. You need to write print function in Manager and Employee classes as well to print all information of Managers and Employees. You need to perform composition to implement this task. Create objects of Manager and Employee classes in main function and call print function for both objects. Print Date class here. Print updated Manager class here. Print updated Employee class here. Print main function here.Build a small program that will generate a 52 card deck that will be used for a Black Jack game. The program should also shuffle the deck. In this exercise you will not build the game but rather just the part where a deck is generated then shuffled. Make sure that you have functions that generate the deck, shuffle the deck and then display the deck. You will use pointers to implement the passing of the deck between functions. Do not use structuresIn c++1. Create a room structure with member-data room dimensions. Write a show () function that displays the room data and an area () function that calculates its face (squaring).In main () create a static array of rooms (Room variables) - the rooms in one apartment. For each of the rooms, display its dimensions and square footage. Determine the total square footage of the apartment.2. Create a Room class with the same member data and member functions:- constructors - by default and with parameters- member-functions set () - to set the corresponding size of the room- member-functions get () - return the corresponding size-show () - outputting a Room object-аrea () - returns the face of the roomIn main (), create:(a) single room objects located in the stack and in dynamic memory, respectively, using all defined constructors(b) 2 arrays of rooms located in the stack and in the dynamic memory (rooms in two apartments), using all defined constructorsFor each of the rooms: set the…

- Language : C++ Subject : OOP Suppose we have a class Rectangle which has two data members, length and width. In addition, there should be a static variable, namely allRectanglesTotalArea which stores the area of all the Rectangles created. Furthermore, there should be a function named calcRectangleArea() which calculates the area of rectangle and adds it to the allRectanglesTotalArea. Write a static function nameddisplayAllRectanglesTotalArea()which displays the value of allRectanglesTotalArea. The main function of the program should look like the following. intmain() { Rectangle r1(5.0,4.0); r1.calcRectangleArea(); Rectangle r2(2.5,4.0); r2.calcRectangleArea(); Rectangle::displayAllRectanglesTotalArea(); return 0; }Q)TCS is a Pakistani courier and logistics company which is based in Karachi.
