A constant object must be__________ ; it cannot be modified after it’s created.
Create an object prototype called Gradebook that will pass an array of grades for a student as a parameter.
- Create a boolean in Gradebook madeHonourRoll that will check whether or not the student has made honour roll
- Create a function within Gradebook, that will calculate the average of the grades passed
- Create a function outside of Gradebook, that will check if the grades are over an 80% average. Return madeHonourRoll as true if the student has made over 80% average.
- Create a function outside Gradebook, called toString(), that will output to console whether or not the student has made the honour roll.
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.

- This program is based in Java, so the response has to be java. Movie Collection Program Create a program that keeps track of your movie collection. Your driver file is movieCollection You will use it to create 4 movie objects. Your Movie class should have a default constructor that does not receive any values and sets all information to default values. You should also have an overload constructor method that has all of the data passed into it. The following information is what each movie object should have: Title Genre Year of release Director. You should have mutator methods that let you set all pieces of information individually. You should have accessor methods that allow you to get each piece of information individually. You should have a toString method that prints out all of the information about a movie at one time. Each piece of information should be on its own line.
