- Introduction In this project, you will complete a C++ class by writing a copy constructor, destructor, and assignment operator. Furthermore, you will write a tester class and a test program and use Valgrind to check that your program is free of memory leaks. Finally, you will submit your project files on GL. If you have submitted programs on GL using shared directories (instead of the submit command), then the submission steps should be familiar. In this project we develop an application which holds the information about a digital art piece. There are two classes in this project. • The Random class generates data. The implementation of this class is provided. It generates random int numbers for colors. To create an object of this class we need to specify min and max values for the constructor. The colors fall between 30 and 37 inclusively. The Art class generates random colors and stores the color values. You implement the Art class. An object of the Art class is a digital masterpiece.…arrow_forwardThis is the question I am stuck on - Radio station KJAVA wants a class to keep track of recordings it plays. Create a class named Recording that contains fields to hold methods for setting and getting a Recording’s title, artist, and playing time in seconds. Write an application that instantiates five Recording objects and prompts the user for values for the data fields. Then prompt the user to enter which field the Recordings should be sorted by—(S)ong title, (A)rtist, or playing (T)ime. Perform the requested sort procedure, and display the Recording objects. This is what I have so far - public class Recording { private String song; private String artist; private int playTime; public void setSong(String title) { this.song = title; } public void setArtist(String name) { this.artist = name; } public void setPlayTime(int time) { this.playTime = time; } public String getSong() { return song; } public String…arrow_forwardDesign an application (submit pseudocode) that declares an array of 12 BaseBallGame objects.
