OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

Magic Square: Create a class MagicSquare that prompts the user for a positive odd integer size, generates a normal magic square of order size, and prints it with numbers right-justified and aligned in evenly-spaced columns. You may assume the numbers in the square are 3 digits or less (i.e. size ≤31). However, each space-separated column should have a width equal to the largest integer in the magic square. (See example transcripts below.) To generate the magic square, use the following algorithm: Assign 1 to our initial current position: the bottom row, middle column. Place each successive value (up to size * size) in the first of the following positions that is unoccupied: (1) one space down and to the right, or (2) one space up. Positions wrap around the sides, top and bottom, as shown in the following example transcripts (user input underlined): Please enter a positive odd integer: 3 492 357 8 16 Please enter a positive odd integer: 5 11 18 25 2 9 10 12 19 21 3 4 6 13 20 22 23 5…What does the function f do? struct Point2D { double x; double y; struct Triangle { Point2D v1; Point2D v2; Point2D v3; }; void f(Triangle&t) { } int temp = 12.5; temp = t.v1.x; t.v1.x = t.v1.y; t.v1.y = temp; } int main () { Triangle mytri; mytri.v1.x = 1.0; mytri.v1.y = 22.5; f (mytri); Swaps values of x and y in vertex 1 of an argument of type Triangle Initializes value of x in vertex 1 of an argument of type Triangle Sets all x,y values in all vertices of an argument of type Triangle Swaps value of x in vertex 1 with value of x in vertex 2, for an argument of type
- Functions with 2D Arrays in Java Write a function named displayElements that takes a two-dimensional array, the size of its rows and columns, then prints every element of a two-dimensional array. Separate every row by a new line and every column by a space. In the main function, call the displayElements function and pass in the required parameters. Output 1 2 3 4 5 6 7 8 9javascript Define a function, myIncludes, that accepts two parameters: an array and a searchValue. myIncludes should return true if the searchValue is an element in the array. Otherwise, myIncludes should return false. example myIncludes([10, 20, 30], 20); // => true myIncludes(['apples', 'bananas', 'citrus'], 'pears'); // => falseplease help me with the pseudocode for this I need it.

Need another class which will contain: An Array of Students (1 above) A count of the number of students in the 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

Specifications In this project, you will write code to determine if a two-dimensional array of ints is a Magic Square. For a two- dimensional array of ints to be a Magic Square all of the following must be true: 1. The array must be square - in other words, the lengths of all rows and all columns must be the same. 2. The array must contain all integers from 1 to n*n, where n is the length of the rows and columns. 3. The sum of the numbers in each diagonal, each row, and each column must be the same. You have been given two classes: • MagicSquareTest.java - Contains JUnit test cases for the MagicSquare class. Your code must pass all these tests. • MagicSquare.java - contains static methods to determine if a two-dimensional array of ints is a Magic Square: o isMagicSquare() - returns true if a two-dimensional array of ints meets all the criteria to be a…

Your cousin owns an automotive maintenance shop that performs routine maintenance on cars. He has asked you to write a program that will provide a list of services (and their respective prices) to users and allow them to choose any, or all, services they would like and display the final price, including a 28% labor charge, a 9% markup if the car is an import, and an 8% sales tax. Task To accomplish the above, do the following: • Write the two methods outlined below. • Test your program and screenshot your successful test. carMaintenance method This method should accept the make of the car as a parameter (e.g., BMW, Ford, Ferrari, etc.). It should display the services and their prices as follows: Services: Oil Change, Tune up, Brake Job, Transmission Service, respectively: 59.99, 111.99, 189.99, 149.99 These should be stored in parallel arrays.
