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.…
Q3: You are designing a program for storing information about Computers. There are different
types of computer for different purposes. Create a class Computer which will have attributes:
CPUName=string, CPUClockSpeed_ghz-float, memory_gb3float. Now derive two classes from
the Computer class, PC which will have attributes: operatingSystem3string, model=int,
hasGPU=boolean and second class will be Smartphone which will have attributes:
OSversion=string, battery_mAH=int. Write following functions for each class:
> Constructor/Destructor
> Deep Copy Constructor
Parameterised Constructor
Getter/Setter for dimension and length/radius
Function to write the information to data file in append mode.
Write a main function to create a dynamic array of PC and smartphone.
Also write a function to get the PC with max CPUClockSpeed_ghz.
Note: Write those functions which are asked. Be Precise in your answer.

Now create a Contestant class with the following characteristics: The Contestant class contains public static arrays that hold talent codes and descriptions. Recall that the talent categories are Singing Dancing, Musical instrument, and Other. The class contains an auto-implemented property that holds a contestants name. The class contains fields for a talent code and description. The set accessor for the code assigns a code only if it is valid. Otherwise, it assigns I for Invalid. The talent description is a read-only property that is assigned a value when the code is set. Modify the GreenvilleRevenue program so that it uses the Contestant class and performs the following tasks: The program prompts the user for the number of contestants in this years competition; the number must be between 0 and 30. The program continues to prompt the user until a valid value is entered. The expected revenue is calculated and displayed. The revenue is $25 per contestant. The program prompts the user for names and talent codes for each contestant entered. Along with the prompt for a talent code, display a list of the valid categories. After data entry is complete, the program displays the valid talent categories and then continuously prompts the user for talent codes and displays the names of all contestants in the category. Appropriate messages are displayed if the entered code is not a character or a valid code.arrow_forwardFailable Initializers - How do I do this practice exercise using Swift code?arrow_forward
