Instructions: In the code editor, you are provided with a treasureChestMagic() function which has the following description: Return type - void Name - treasureChestMagic Parameters - an address of an integer Description - updates the value of a certain integer randomly You do not have to worry about how the treasureChestMagic() function works. All you have to do is ask the user for an integer and then call the treasureChestMagic() function, passing the address of that integer you just asked. Finally, print the updated value of the integer inputted by the user. Please create a main code for my function that works with this. This is my code: #include<stdio.h>#include<math.h> void treasureChestMagic(int*); int main(void) { // TODO: Write your code here return 0;} void treasureChestMagic(int *n) { int temp = *n; int temp2 = temp; *n = *n + 5 - 5 * 5 / 5; temp2 = (int) pow(2, 3); if(temp % 3 == 0) { *n = temp * 10; } else if(temp %…
question in javascript 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.

Java Validation Programming Android [User Name] User can input value (a~z) (A~Z). User cannot input value number between 0 and 9. Show an error if user input it. User cannot input value contains symbol (ex: !@#$). Show an error if user input it. User must fill the form to proceed, Show an error if fill form is empty. User only able to input value less than 30 characters. Show an error if exceed. With the validation described above.

5 Stars (1).pdf PDF O File | C:/Users/19377/Downloads/5%20Stars%20(1).pdf + U DL uI D Purpose To review interfaces Directions Your task for this lab is to implement and test a class to store ratings of items. Your Rating class should have the following fields and methods: private double sumofRatings the sum of all of the ratings private int raters the number of people who have rated an item public Rating () initialize both fields to zero public Rating(double sumOfRatings, int raters) to the parameter values initialize the fields increase the sumOfRatings by public void addRating (double newRating) newRating and increase the number of raters by one public double getAverageRating () are no raters so far, return 0.0 return the average rating; if there public String toString () reviews it is based on; display the average rating and how many for example, if the sum of the ratings is 32 and that is based on ratings from ten people, the toString method will return "3.2 based on 10 reviews"…
in addition to java programming please include the flowchart of the program for the project and the pseudocode of the program for the project. Create a program to enter grades and calculate averages and letter grades. Need a class which will contain: Student Name Student Id Student Grades (an array of 3 grades) A constructor that clears the student data (use -1 for unset grades) Get functions for items a, b, and c, average, and letter grade Set functions for items a, n, and c Note that the get and set functions for Student grades need an argument for the grade index. Need another class which will contain: An Array of Students (1 above) A count of number of students in use You need to create a menu interface that allows you to: Add new students Enter test grades Display all the students with their names, ids, test grades, average, and letter grade Exit the program Add comments and use proper indentation. Nice Features: I would like that system to accept a student with no…
Integer userValue is read from input. Assume userValue is greater than 1000 and less than 99999. Assign tensDigit with userValue's tens place value. Ex: If the input is 15876, then the output is: The value in the tens place is: 7 2 3 public class ValueFinder { 4 5 6 7 8 9 10 11 12 13 GHE 14 15 16} public static void main(String[] args) { new Scanner(System.in); } Scanner scnr int userValue; int tensDigit; int tempVal; userValue = scnr.nextInt(); Your code goes here */ 11 System.out.println("The value in the tens place is: + tensDigit);
IN C# PLEASE Create class Cube. The class has attributes length and width and depth, each of which defaults to 1. It has read-only properties that calculate the Perimeter and the Area for a side of the cube, and another that calculates the cubed feet for the cube. (You will have to research how to do that calculation online) It has properties for length and width and depth. The set accessors should verify that length and width and depth are all floating-point numbers greater than 0.0 and less than 20.0. Write an app to test class Cube by creating 3 cubes of different sizes.
Travel Tickets Company sells tickets for airlines, tours, and other travel-related services. Because ticket agents frequently mistype long ticket numbers, Travel Tickets has asked you to write an application that indicates invalid ticket number entries. The class prompts a ticket agent to enter a six-digit ticket number. Ticket numbers are designed so that if you drop the last digit of the number, then divide the number by 7, the remainder of the division will be identical to the last dropped digit. Accept the ticket number from the agent and verify whether it is a valid number. Test the application with the following ticket numbers: . 123454; the comparison should evaluate to true . 147103; the comparison should evaluate to true . 154123; the comparison should evaluate to false Save the program as TicketNumber.java.
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.…
PART B: JUnit Testing Write a Java program according to the following: Create a Multiple.java class. Create the following two static methods (with return type float): SquareRoot() and CubeRoot(). SquareRoot) method should take two arguments and return the float value at the end. CubeRoot() method should take three arguments and return the float value at the end. Create a test class with the name MultipleTest.java. In this class, import the following libraries at the top of this file import org.junit. Before; import org.junit. Test; import static org.junit.Assert.assertEquals; Create an object of Calculator.java class by writing the following code in CalculatorTest.java class: private Multiple multiple; @Before public void setup() {this.multiple new Multiple():) 4. Generate the JUnit test classes for both the methods one by one. Declare and initialize the required variables to pass those to the methods. Store the expected result in one of the variables and then compare it with the…
