- Software engineering Question: Q.No.4. The client's ultimate objective is to have an online software system that gives information about the movies that the client sells to customers online. The system gives information about movies and actors/actresses. That is, the system should be accessed online. Each movie is identified by title and year of release. A movie has a genre (drama, comedy, etc.), a running time, and one director. A movie is made at a movie studio and may have multiple producers (people in charge of the movie production). A movie studio has a unique name and address, and may make one or more movies. Producers are identified by name and date of birth and produce one or more movies. Directors are also identified by name and date of birth and direct one or more movies. Assume that directors don’t act or produce movies. Actors are identified by name and date of birth, and may appear in one or more movies. An actor who appears in a movie, has a role. There may…Consider the definition of the class product Type as given in Exercise 8. Answer the following questions. (1, 2, 3, 5, 7) a. Write the definition of the function set so that instance variables are set according to the paramaters. Instance variables quantitieslnStock, price, and discount must be nonnegative. b. Write the definition of the function print to output the values of the instance variables. c Write the definition of the function setQuantitiesInStock to set the value of the instance variable quantitiesInStock according to the parameter. d. Write the definition of the function updateQuantitiesInStock to update the value of instance variable quantitiesInStock by adding the value of the parameter. e. Write the definition of the function getQuantitiesInStock to return the value of instance variable quantitiesInStock. f. Write the definition of the function setPrice to set the value of the instance variable price according to the parameter. g. Write the definition of the function getPrice to return the value of the instance variable price. h. Write the definition of the function setDiscount to set the value of the instance variable discount according to the parameter. i. Write the definition of the function getDiscount to return the value of the instance variable discount.Assume the definition of class houseType as given in Exercise 11.

- The concept of public and private class members is part of an approach called object oriented programming. This approach is relevant to many different programming languages and each implements and supports it in slightly different ways. Which of the following sentences are correct about public and private as implemented in python? Python does not support the concepts of public and private members of a class. Python does not directly enforce public and private member access and so will not generate an error if you fail to respect the convention. Just like other languages that support Object Oriented Programming, such as C++ and Java, Python strictly enforces the concept of public and private class members and will generate an error when it runs if you try to access a private member from outside of the class. Python supports the concept of public and private through convention - by adding an underscore '_' at the beginning of the member function or variable.What is the main goal of Object oriented programming? O Monitoring maintenance Information hiding Ease of evolution Encapsulating code Which from the following is a feature * that allows us to perform a single action in different ways. O Polymorphism Inheritance ) Abstraction O EncapsulationCourse Title: Object Oriented Analysis and Design Question : The automation in our lives has changes much, and so as in our purchasing and selling approaches. Big food chains and Pizza makers are also in quest of means to automate their production so that best and quick services can be provided to the customers. A company called “Eating Bytes” has gone one step forward. The company is planning to use the self-driving cars for their orders delivery. Furthermore, the company has taken its entire kitchen to the inside of the driverless car. Once an order is received from a customer, the car will be heading towards the destination and in the meantime the pizza will be baked, prepared and packed within that car. So, from order taking to order delivery, all the processes have been automated. Identify the Objects and draw a Sequence diagram for the above scenario that how the different objects interact and communicate among each other.
