This tips will help you What You Must Implement:You must define a class named MediaRental that implements the MediaRentalInt interface functionality(index A). You must define classes that support the functionality specified by the interface. The followingspecifications are associated with the project:1. Define a class named MediaRental. Feel free to add any instance variables you understand are needed or anyprivate methods. Do not add any public methods (beyond the ones specified in the MediaRentalInt interface).2. The media rental system keeps track of customers and media (movies ,music albums and games). A customerhas a name, address as string , a plan and two lists. One list represent the media the customer is interested inreceiving and the second one represents the media…

- It's messy that in the Balrog class's getDamage() function and the Cyberdemon class's getDamage() function we have to write the name of the species before calling the Demon class's getDamage() function. It would be better if the Demon class's getDamage() function could print the name of the species. Taking this a step further, it would be even better if we didn't have to repeat the cout statement "The <whatever> attacks for ?? points!" in every class's getDamage() function. It would be better if that cout statement could occur just once, in the Creature class's getDamage() function. In the Creature class's getDamage() function, insert the following statement:cout << "The " << getSpecies() << " attacks for " << damage << " points!" << endl; Delete (or, if you prefer, comment out) the similar cout statements that appear in the getDamage() function of each of the 5 derived classes.

First you will need to make a Timer object. This object should function like a traditional stopwatch with methods for starting, stopping, resetting, and reporting back times. The design of the object itself is up to you (it should minimally contain methods for the aforementioned ideas), but it must consist of a solitary object that provides interfaces appropriate for being compositionally included as part of a sorting object to facilitate the time keeping portion of this exercise. Make sure you have a properly separated specification and implementation file for your Timer/Stopwatch object. The second object you will make should be a data housing object that has methods that enable client code to read in the formatted contents of data files, house the data in memory, and execute bubble sort, selection sort, and insertion sort algorithms in a timed fashion with the assistance of your…arrow_forward
