Consider the implementation of the data structure stack. If we create an integer stack then the push and pop operations will handle only integer elements. If we create a character stack then the push and pop operations will handle only character type elements. But creating so many copies of implementation makes the code complex to maintain. Hence the principle of genericity is used and a template class can be created. This container class can handle any data type element at run time.In the same contrast explain the importance of modeling in object oriented
Plagiarized answer will be given thumbsdown.
Step by step
Solved in 5 steps
- Consider the data structure stack's implementation. If we make an integer stack, the push and pop actions will only work with integer items. When we construct a character stack, the push and pop operations will only handle components of the character type. However, making so many copies of the implementation makes the code difficult to maintain. As a result, the genericity principle is applied, and a template class may be constructed. At runtime, this container class can handle any data type element. Explain the significance of modeling in object oriented programming using the same comparison.Write a c++ code that compare the times to traverse a list (containing a large number of elements) implemented in an array, in a simple linked list, and in an unrolled linked list. In this experiment, you need to generate a large list, store it in each representation, and then measure the time to traverse the list in each representation. For the array, this is almost straightforward: Fill the array and then do a sequential scan. Here is the thing to watch for: When you fill the array, it all gets read into cache. So, somehow you need to ensure that almost all of the array is NOT in cache before you do your traversal. One thing you can do is make your array big enough that most of it will not fit in cache at once. You need to make sure that the node capacity is not too small, or it will behave too much like a simple linked list.Develop a program in C++ that will implement a Josephus Circle using circular linked list. There are n people standing in a circle waiting to be executed. The counting out begins at some point in the circle and proceeds around the circle in a fixed direction. In each step, a certain number of people are skipped and the next person is executed. The elimination proceeds around the circle (which is becoming smaller and smaller as the executed people are removed), until only the last person remains, who is given freedom. Given the total number of persons n and a number m which indicates that m-1 persons are skipped and mth person is killed in circle. The task is to choose the place in the initial circle so that you are the last one remaining and so survive.
- implemented a system for maintaining rental contracts for a small parking lot. With our knowledge of ordered structures, we now return to that example to incorporate a new feature—an alphabetical listing of contracts. As customers rent spaces from the parking office, contracts are added to a generic list of associations between renter names and lot assignments. We now change that structure to reflect a better means of keeping track of this information—an ordered list of comparable associations.Develop a program in C++ that will implement a Josephus Circle using circular linked list.

- you are to design a printer queue that is responsible for handling the printing requests coming from different users. You have to take into consideration that users have different levels of priorities. Each user has an identification number and a password, in addition to printing priorities. One good idea is to design the queue using an array or pointers while preserving the first-in first-out concept of the queue. For every printing request received, the program should check the priorities of that request and whether it can be moved forward in the queue to be served by the printer prior to serving the other requests. Using the programming language of your choice (preferably C++), write the printer queue that would handle the user request. The program must allow for requests coming from different users or from one user. Note: I need a working C++ code for this problem, and i need priorities.Develop a BST implementation that represents the BST with three arrays (preallocated to the maximum size given in the constructor): one with the keys, one with array indices corresponding to left links, and one with array indices corresponding to right links. Compare the performance of your program with that of the standard implementation.This question is in the course of Data Structures. Please solve in C programming language and DO NOT add any comments in between the lines or anything extraneous whatsoever (that a student would not typically need for a correct answer). In this picture, you will see a short piece of code for destroying an SLL (Singly linked list). I want to write the destroy function recursively.The answer is needed ASAP.Thank you so much in advance!
- A basic console program for car rental system is needed to be implemented by using linked list and tree in Java (Eclipse). The online rent a car system serves as a database storing available rental cars with their associated retailer. The system checks and shows a list of accessible rental cars to the user for a given time period. Then, they can book their desired car from the related store by using the program. The development language of the project is Java and 2 types of data structures are used: linked list and tree. All of the available option details of the cars are accumulated by linked lists and the customer information is stored in the tree.The implementation of a queue in an array, as given in this chapter, uses the variable count to determine whether the queue is empty or full. You can also use the variable count to return the number of elements in the queue. On the other hand, class linkedQueueType does not use such a variable to keep track of the number of elements in the queue. Redefine the class linkedQueueType by adding the variable count to keep track of the number of elements in the queue. Modify the definitions of the functions addQueue and deleteQueue as necessary. Add the function queueCount to return the number of elements in the queue. Also, write a program to test various operations of the class you defined.Implement a simulator for a process scheduling system using a heap. Jobs will be read from a file in this system that contains the job id, a six-character string, the length in seconds, and the priority of the job, an integer whose greater value indicates a higher priority. Each work will also receive an arrival number, which is an integer that indicates the order in which it arrived. The output of the simulation should include the job id, priority, duration, and completion time (relative to the simulation's start time of 0).
