- Two ways to get a "self" in an object are: a) (1) to use the closure + box with dummy value changed to the object trick, or (2) to pass in self as an implicit parameter, by passing a function that returns the object when given a 'self message b) (1) to add an else clause to dynamic dispatch or (2) to pass in self as an explicit parameter, using something like msg/self c) (1) to use the closure + box with dummy value changed to the object trick, or (2) to add an else clause to dynamic dispatch d) (1) to use the closure + box with dummy value changed to the object trick, or (2) to pass in self as an explicit parameter, using something like msg/selfYou will create Cart class as a context class to get total price and add product.◦ To implement Strategy pattern, depending on the country of shipping, the relevant customsduty is charged and the shipping cost of Europe Shopping, America Shopping increases. Largeproducts (XL-size) have an additional charge. Create AmericaShopping and EuropeShoppingconcrete class.In the USA, the duty tax is 1% and the base delivery fee is $15. In America, an additional taxdifferent from the customs tax is applied and this tax is 0.75%. Customs duty should be addedto the item fee for each item.In Europe, the customs duty is 1.5% and the base delivery fee is £11.In America, $5 should be added to the shipping fee when each item is added. But if the addedproduct size is XL, $10 should be added to the shipping fee. In Europe, this should only be doneif the product size is XL.C++ CHALLENGE ACTIVITY 7.11.2: Constructor overloading.

- How to decide if your variable should be declared as an enum type or any other data types? Support your answer with examples. plz avoid copied answers, my assignment will be submitted through turnitin and plagiarism will be detected.Problem:Write a program to simulate the work of processes scheduler by using RR algorithm. Theprogram should have three classes which are:1. Process Class: This class represents the process where it has process id, executetime and completion time. Arrival is assumed to be zero all times. Process id shouldbe unique and the class create it for each process. Provide the required methodsaccordingly.2. RRSchedule Class: This class represents the work of the scheduler. It has mainlytwo lists of processes, quantum size, and clock. One of the list will be as a recordof the processes while the other is to work on to execute the process in CPU. Theclock should be a simple counter to represent timing to run the list of processes.The method list should be as following:a. Pop method: to remove the process from the top of the list.b. Push method: to insert the processes at the end of list after it is interruptedand still has to go to CPU again.c. RunRR method: to represent the job of RR scheduler.…Saved Which of the following statements about UML class diagrams is false?
