This is an object oriented programming question The code should be in C++ language Create a class Student having a private data members S_ID, S_Name and S_CGPA. Now create a public member functions void getID(), void getName() and getCGPA() and finally to display all the data members, create a function void display(). In the main(), create an array of student class, size of the array should be taken from user at run time and call all the functions defined in the class. Sample Output: Student 1 Enter ID: 1 Enter Name: Ali Enter CGPA: 2.5 Student 2 Enter ID: 2 Enter Name: Ahmed Enter CGPA: 2.9 Student 3 Enter ID: 3 Enter Name: Zain Enter CGPA: 3.4 Student 1 informationID: 1 Name: Ali CGPA: 2.5 Student 2 information ID: 2 Name: Ahmed CGPA: 2.9 Student 3 information ID: 3 Name: Zain CGPA: 3.4
Make Album in c++ You are going to develop a new class named Album. This class will has (at a minimum) teh following attributes and features: Attributes: Album Title Artist Name Array of song names (Track Listing) Array of track lengths (decide on a unit) At most there can be 20 songs on an album. Behaviors: Default and at least one argumented constructor Appropriate getters for attributes bool addTrack(string name, type duration) - adds track to album. You decide type on duration. Make sure you document what dis is. getAlbumLength() - method dat returns total length of album matching watever units / type you decide. getAlbumLength_string() - method dat returns total length of album in mm:ss format string. I would suggest using you're other getLength function here. string shuffleAlbum(int n) - method dat returns a formatted string made up of n random tracks from teh album. The string will be in the format [1] track_name (mm:ss), [2] track_name (mm:ss)... Well formatted print()…

C++ Friend function concepts Do not use operator overloading Create a class User with private member variables "id". In the class define a function increment_user_id() which will increment the id and return it as well. Create another method "void show_Id()" to show the id for a particular object. Create a constructor of User class where increment the Id by calling the increment_user_id() method for every new object . Finally create two objects of the class and print their corresponding id's on console.
c++ Friend function concepts Do not use operator overloading Create a class Circle with member variable radius R of type float. Create a constructor for assigning value to R and a method "int compare(Circle c)" for comparing the radii. In main method, create two objects of Circle and compare their radii and display which one is bigger
Object oriented programming C++ Use Classes Write a C++ program in which each flight is required to have a date of departure, a time of departure, a date of arrival and a time of arrival. Furthermore, each flight has a unique flight ID and the information whether the flight is direct or not.Create a C++ class to model a flight. (Note: Make separate classes for Date and Time and use composition).add two integer data members to the Flight class, one to store the total number of seats in the flight and the other to store the number of seats that have been reserved. Provide all standard functions in each of the Date, Time and Flight classes (Constructors, set/get methods and display methods etc.).Add a member function delayFlight(int) in the Flight class to delay the flight by the number of minutes pass as input to this function. (For simplicity, assume that delaying a flight will not change the Date). Add a member function reserveSeat(int) which reserves the number of seats passed as…
c++ please The Critter class is a base class with some basic functionality for running simulations of different kinds of critters. Critters can move, act, and remember their history. A typical simulation contains a number of critters of different types. In each step of the simulation, the act member function will be called on each critter. Define a class Sloth derived from Critter that simulates a sloth. Sloths alternate between eating and sleeping. Add the word "eat" or "sleep" to the history each time the act function is called. The implementation of the Critter class is not shown. Complete the following file: sloth_Tester.cpp #include <iostream>using namespace std; #include "critter.h" /**A sloth eats and sleeps.*/class Sloth : public Critter{public:Sloth();. . .private:. . .}; Sloth::Sloth(){. . .} void Sloth::act(){if (...){add_history("eat");...}else{add_history("sleep");...}} int main(){Sloth sloth;sloth.act();cout << sloth.get_history() << endl;cout <<…
C++ Language Please Write a program that implements four classes: NPC, Flying, Walking, and Generic for a fantasy roleplaying game. Each class should have the following attributes and methods: NPC -a parent class that defines methods and an attribute common to all non-player characters (npc) in the game. a private string variable named name, for storing the name of the npc. a default constructor for setting name to "placeholder". an overloaded constructor that sets name to a string argument passed to it. setName - a mutator for updating the name attribute getName - an accessor for returning the npc name printStats - a pure virtual function that will be overridden by each NPC subclass. Flying - a subclass of NPC that defines a flying npc in the game a private int variable named flightSpeed for tracking the speed of the npc. a default constructor for setting flightSpeed to 0 and name to "Flying" using setName. setFlightSpeed - a mutator that accepts an integer as it's only argument…
