- Using python: Suppose a call center has three levels of employees—respondent, manager, and director. An incoming telephone call must first be allocated to a respondent who is free. If the respondent cannot handle the call, the call must be escalated to a manager. If the manager is occupied, then the call should be escalated to a director. Design YOUR OWN classes and data structures for this problem. Implement a method dispatchCall() that assigns a call to the first available employee.A software development company re-uses its knowledge of operations performed by category of software systems. This company creates generic list of methods related to each category. Consider there is an e-Shop category, you are given a task to list at least 10 methods for e-Shop. Use the suitable option of object oriented programming to list down the method for e-Shop (write code) A pharmacy store wants to sell its products online. Write code that utilizes the code written in (a) to define ePharmacy methods A grocery store wants to sell its products online. Write code that utilizes the code written in (a) to define eGrocery methods Draw a complete class diagram for ePharmacy that presents its relationship with code (a) as well Draw a complete class diagram for eGrocery that presents its relationship with code (a) as wellWrite a class Point for 2D Cartesian co-ordinates. The class should have 2 fields: abscissa(x) and ordinately). The class should have a method which takes a Point object as parameter and finds the distance between the two points (calling object & argument). The class should also have a static method that takes 2 point objects and returns their midpoint as a new Point object. (No driver class or no other methods required) The distance (d) between 2 points (x1, y1) and (x2, y2) is given by: d = (x1 – x2)2 + (y1 – y2)² The midpoint (x3, y3) between 2 points (x1, y1) and (x2, y2) is given by: x3 = (x1+x2)/2 y3 = (y1+y2)/2
- Assume B is a subclass of A. Which of the statements about the following assignment is false? A a = new B(); We can assign anything to variable a that has a subtype of B. We can call on a any method defined in A. We can call on a any method defined in B. We can assign anything to variable a that has a subtype of A.Now we want to create an Object oriented System for a shopping mall. It has Items with name, manufacturer and price. Provide constructors. Getters, setters, toString methods. We add several items to Store. For that create a store class having name and arraylist of items, Provide Constructors, getters/setters and toString(), in addition you have to provide a method add which add new item to the array. The main function that does these things looks as follows: Public static void main(Strings[] args) { Item shampoo2(“pantene”, “Procter & Gamble”,100), noodles(“Noodles”, “knorr”, 50); // add further items. Store abcSuperStore; abcSuperStore.add(shampoo2); abcSuperStore.add(noodles); … abcSuperStore.sale(shampoo2); a bcSuperStore.sale(noodles);Suppose a call center has three levels of employees: respondent, manager, and director. An incoming telephone call must first be allocated to a respondent who is free. If the respondent cannot handle the call, the call must be escalated to a manager. If the manager is occupied, then the call should be escalated to a director. Design YOUR OWN classes and data structures for this problem. Implement a method dispatchCall() that assigns a call to the first available employee.
- Please help me design a SimulationProject.cpp in C++. THANK YOU! For this assignment, we will simulate boarding procedures for Airworthy Airlines. The Airline's current procedure is as follows: pre-board in the following order: families with young children or people who need help (e.g., wheelchair) first class and/or business class passengers elite passengers (frequent fliers) and those passengers seated in exit rows conduct general boarding in reverse, from the back of the plane to the front in the following order: rows 23-26 rows 17-22 rows 11-16 rows 5-10 Airworthy is considering revising their boarding procedure such that general boarding is done randomly, meaning the first passenger in line for general boarding is the first passenger to board (i.e., general boarding passengers all have the same priority). Airworthy suspects this random general boarding method will improve the flow of passengers, getting them on board and seated more quickly. It is also less labor-intensive…In C++ Language using Functions and Pointers PROBLEM: Consider the elevator in the Faculty of Engineering (5 storey). Write a program which accepts the floor number where a passenger (student/faculty/other personnel) will ride the elevator. The passenger can then input the target destination floor. SPECIFICATIONS: Implement the class diagram below: Inside the main method, create an instance of the class Elevator. Use the goUp or goDown methods to generate the program display.Passenger can ride in any floor (1,2,3,4 or 5). Program will prompt the user with the target destination floor. After the user input: Program will display the floors which the elevator passes through, and finally the destination floor. Elevator will not move if the input for destination floor is the same as the present floor. Program will notify the user and then terminate. Program will also terminate if the input destination is not 1,2,3,4 or 5. You’re free to format the input/output display. Observe proper…Now we want to create an Object oriented System for a shopping mall. It has Items with name, manufacturer and price. Provide constructors. Getters, setters, toString methods. We add several items to Store. For that create a store class having name and array of items, Provide Constructors, getters/setters and toString(), in addition you have to provide a method add which add new item to the array.
- This is the question: Design and implement a class called Bug, which represents a bug moving along a horizontal wire. The bug can only move for one unit of distance at a time, in the direction it is facing. The bug can also turn to reverse direction. For your design, create a UML Class diagram similar to Figure 5.5 on page 180 of the textbook. Note that you need to include the constructor in the methods section if you code a constructor. Bug will require a toString method to return the current position and which direction the bug is facing to the driver so it can be output.Hint: Remember that a horizontal line has a zero position in the middle with positive to the right and negative to theleft. Consider that a bug will land on the wire at some point before starting along the wire.Write an interactive test driver that instantiates a Bug, then allows the user to manipulate it with simple commands like Output (to see the position and direction), Move, Turn, Exit ... single letters work…using python language Suppose a call center has three levels of employees—respondent, manager, and director.

Implement a method dispatchCall() that assigns a call to the first available employee.Please help write this in C++, I am kinda lost. bagDifference: The difference of two bags is a new bag containing the entries that would be left in one bag after removing those that also occur in the second. Design and specify a method difference for the ArrayBag that returns as a new bag the difference of the bag receiving the call to the method and the bag that is the method's parameter. The method signature is: ArrayBag<ItemType> bagDifference(const ArrayBag<ItemType> &otherBag) const; Note that the difference of two bags might contain duplicate items. For example, if object x occurs five times in one bag and twice in another, the difference of these bags contains x three times. Here is the all of the file: ArrayBag.cpp: #include <string>#include "ArrayBag.h" template <class T>ArrayBag<T>::ArrayBag() : itemCount(0) {// itemCount = 0;} template <class T>ArrayBag<T>::ArrayBag(const ArrayBag& orig) {itemCount =…
