Randomized Select Algorithm

A randomized algorithm is defined as one that uses a certain amount of randomization in its logic or operation. It is said to be an algorithm that depends on the random number to perform its operation. It is used for reducing the overall time complexity, space complexity in the standard algorithm. The randomized algorithm uses the concept of random numbers to find the solutions to the different kinds of problems and also to improve the problem solutions.

As the first step in writing an application for the local book store, we will design and implement a Book class that will define the data structure of the application. Each book has a name, author, type (paperback, hardback, magazine), integer ID and pageCount. Provide some data validation in the appropriate method to ensure that the ID and pageCount are not negative. Design and implement a Book class with separation, i.e., separate all functions and methods into both the prototype and an implementation below the main. Provide constructor methods for Book(void), Book(name, author), and one for all components Book(name, author, type, ID, pageCount) Provide accessor (get and set) methods for each property as well as a display method. Provide data validation for the ID and pageCount in the appropriate methods.

Image one is my code, I wanted to make some change to the blue part's code. The code I written in red(see image 1) is the method to check that an integer has exactly 5 digits is provided for you (fiveDigits). You just need to call it appropriately in your code(the part in blue square)! Notice that the fiveDigits method returns a boolean - think carefully about how you should use this return type to reprompt the user until they enter a valid zip code. And I want the same output be like (see image 2) for the invalid zip code part: I should only reprompt the user with the message "Invalid zip-code, enter valid zip-code: " until they enter a valid zip code. Similarly, if the user enters an invalid pain level, you should reprompt the user with the message "Invalid pain level, enter valid pain level (1-10): " until they enter a valid pain level.
