(Fibonacci number iterator) Define an iterator class named Fibonacci Iterator for iterating Fibonacci numbers. The constructor takes an argument that specifies the limit of the maximum Fibonacci number. For example, new Fibonacci Iterator (23302) creates an iterator that iterates Fibonacci numbers less than or equal to 23302. Write a test

- (CLO3) Read the following description and answer the following questions about it: Problem Description: A car dealership allows customer to purchase their new cars with different options. At this time, those options are color, model, and air condition, as shown below in class CustomerOrder. Of course, the dealership wants the software to be flexible enough to be able to add more options in the future, if needed. CustomerOrder -carColor: String -carModel: String -hasAirCondition: boolean Q1) Write the full required code in Java to use the Builder design pattern to create class CustomerOrder. Q2) Write a Java main() method to create an object of class CustomerOrder with color "red" and without air condition.arrow_forwardPlease help me with this , I am stuck ! PLEASE WRITE IT IN C++ Thanks 1) bagUnion: The union of two bags is a new bag containing the combined contents of the original two bags. Design and specify a method union for the ArrayBag that returns as a new bag the union of the bag receiving the call to the method and the bag that is the method's parameter. The method signature (which should appear in the .h file and be implemented in the .cpp file is: ArrayBag<T> bagUnion(const ArrayBag<T> &otherBag) const; This method would be called in main() with: ArrayBag<int> bag1u2 = bag1.bagUnion(bag2); Note that the union of two bags might contain duplicate items. For example, if object x occurs five times in one bag and twice in another, the union of these bags contains x seven times. The union does not affect the contents of the original bags. Here is the main file: #include <cstdlib>#include <iostream>#include "ArrayBag.h"using namespace std; template…arrow_forward(Game: ATM machine) Use the Account class created in our previous Lab Exercise to simulate an ATM machine. Create ten accounts in an array with id 0, 1, . . ., 9, and initial balance $100. The system prompts the user to enter an id. If the id is entered incorrectly, ask the user to enter a correct id. Once an id is accepted, the main menu is displayed as shown in the sample run. You can enter a choice 1 for viewing the current balance, 2 for withdrawing money, 3 for depositing money, and 4 for exiting the main menu. Once you exit, the system will prompt for an id again. Thus, once the system starts, it will not stop.arrow_forward

Write a test class to find the larger oftwo instances of ComparableSquareobjects.arrow_forwardEdit only the class definition. DO NOT CHANGE the code given under 'main' please. Steps: Additionally implement any Python Magic/Dunder methods such that instances of the class minimally:1. Support addition, subtraction, equality operations and the built-in abs function2.

Support a string representation that displays the class name and coordinates stored by the instance: i.e. for an object initialized as: Vector(0, 3), the string representation should be ‘Vector(0, 3)’The code given under main tests for each of the program requirements and subsequently uses the turtle module to plot randomly generated points rotated.

- 1- Write a class that allows you to define complex numbers in C++ and call it complex. The class contains two private members named real and img. It also has a constructor to initialize its members to values other than zero. Then, write a four methods that implement the basic mathematical operations (+,-.*) for two complex numbers. 2- The purpose of the method resize() in the IntegerArray class below is to dynamically change the size of the IntegerArray instance. This methid is implemented as follows: 1. create a new array with the desired size 2. copy the data form the old to new one 3. delete the old data 4. Make the old data pointer points to the newly created data 5. update the size field your task is to write the resize() method based on the above five steps. #include int main() { using namespace std; IntegerArray a(2); a.data[0] = 4; class IntegerArray { public: a.data[1] = 2; int *data; a.resize(5); int size; cout size = size; solve number 2 } -IntegerArray()) { delete[] data;…arrow_forward(Algebra: quadratic equations) Design a class named QuadraticEquation for a quadratic equation ax² + bx + x = 0. The class contains: 1 The private data fields a, b, and c that represent three coefficients. 1 A constructor for the arguments for a, b, and c. 1 Three get methods for a, b, and c. A method named getDiscriminant() that returns the discriminant, which is b? – 4ac. The methods named getRoot1() and getRoot2() for returning the two roots of the equation using these formulas: -b + Vb? – 4ac -b - Vb? – 4ac and r2 2a 2a These methods are useful only if the discriminant is nonnegative. Let these meth- ods return 0 if the discriminant is negative. Draw the UML diagram for the class, and then implement the class. Write a test program that prompts the user to enter values for a, b, and c and displays the result based on the discriminant. If the discriminant is positive, display the two roots. If the discriminant is 0, display the one root. Otherwise, display "The equation has no…arrow_forwardThis program extends the earlier "Online shopping cart" program.

The Address class will have three private instance variables: an int named street_number a String named street_name and a String named state. Write three constructors for the Address class: an empty constructor (no input parameters) that initializes the three instance variables with default values of your choice, a constructor that takes the street values as input but defaults the state to "Arizona", and a constructor that takes all three pieces of information as input Next create a driver class named Main.java. Put public static void main here and test out your class by creating three instances of Address, one using each of the constructors. You can choose the particular address values that are used. I recommend you make them up and do not use actual addresses. Run your code to make sure it works. Next add the following public methods to the Address class and test them from main as you go: Write getters and…arrow_forward
