Linked List-Based Queue Implementation

Implement Queue using a Linked List.

• Use the language library LinkedList
• Queue methods will call the LinkedList methods
• You can use string as the object

Instead of using an array, as the QueueLab did, here you will use a Linked List from your language's library. Implement all the methods of Stack : enqueue(), dequeue(), size(), printQueue(), etc, using calls to the linked list methods that correspond to the actions need. In the array implementation, you wrote code to manipulate the array. For this linked list implementation, methods already exist.

Before the underlying implementation of queue was array, now the underlying implementation of queue will be Linked list.

7.24 LAB: Triangle area comparison (classes)

Language: C++

Given class Triangle (in files Triangle.h and Triangle.cpp), complete main() to read and set the base and height of triangle1 and of triangle2, determine which triangle's area is larger, and output that triangle's info, making use of Triangle's relevant member functions.

Ex: If the input is:

3.0 4.0
4.0 5.0

where 3.0 is triangle1's base, 4.0 is triangle1's height, 4.0 is triangle2's base, and 5.0 is triangle2's height, the output is:

Triangle with larger area:
Base: 4.00
Height: 5.00
Area: 10.00

In the C programming language:

Pretend you are an astrophysicist making a report on the distances to the 50 brightest stars.
You need to print out a nice table sorted by distance to include in your report.

Using data in input.txt, write a program that can read in the included file input.txt.

Use scanf or fscanf (or any other function you prefer) to read the comma separated values (CSV) into an array of structs representing each record.

Once all records are loaded, sort the list by the distance field. Alternatively, you can keep the array
sorted by its distance during reading. Use any sorting function you want.

Save the data sorted by the distance field (lowest to highest) in another file called "distance.txt".
Save only the following fields in this order:

   Distance
   Name
   Bayer Name
   right ascension
   declination

Make sure that the columns line up nicely and that the header is printed before the data.

input.txt contains:

7.28 LAB: Artwork label (classes/constructors). Written in C++

Given main(), complete the Artist class (in files Artist.h and Artist.cpp) with constructors to initialize an artist's information, get member functions, and a PrintInfo() member function. The default constructor should initialize the artist's name to "None" and the years of birth and death to 0. PrintInfo() should display Artist Name, born XXXX if the year of death is -1 or Artist Name (XXXX-YYYY) otherwise.

Complete the Artwork class (in files Artwork.h and Artwork.cpp) with constructors to initialize an artwork's information, get member functions, and a PrintInfo() member function. The constructor should by default initialize the title to "None", the year created to 0. Declare a private field of type Artist in the Artwork class.

Ex. If the input is:

Pablo Picasso
1881
1973
Three Musicians
1921

the output is:

Artist: Pablo Picasso (1881-1973)
Title: Three Musicians, 1921

If the input is:

Brice Marden
1938
-1
Distant Muses
2000

the output is:

Artist: Brice Marden, born 1938
Title: Distant Muses, 2000

Design a GUI application for the Bank Account assignment you did in the File IO module.

It can be simple as a single user app with three buttons - checkBalance, Withdraw, Deposit - textbox for entering the amount.

On Click of buttons, you can show the current balance in a dialog box.

If you have more interest, you can expand it further according to your design of the application

In python

Please show codes and output.

The calculator must be in a standard size not too small not to big

*Not in C++ Language! Pleaseeee in Java?!!*

Programming Exercise 3.20 required you to design a PID manager that allocated a unique process
identifier to each process. Exercise 4.20 required you to modify your solution to Exercise 3.20 by writing
a program that created a number of threads that requested and released process identifiers. Now
modify your solution to Exercise 4.20 by ensuring that the data structure used to represent the
availability of process identifiers is safe from race conditions. Use Pthreads mutex locks.

if there is any questions, leave a comment. Thank you.

We are going to create our own implementation of the game “FloodIt”. Several versions of this game can be found, for example a version for android, on which this description is based, here. Several Web versions are available

In this game, a square board is filled with dots, each having one of six possible colours. The players initially “captures” the top left dot. The player keeps choosing one of the six colours. Each time a colour is chosen, the dots that have already been captured turn into that colour. Each dot that is a neighbour¹ of a captured dot, and whose colour matches the newly selected colour becomes itself captured. The game ends once the entire board is captured (the board is “flooded” because all the dots have the same colour). As the game can only progress (a captured dot cannot be lost), the issue of the game is certain. The goal is thus to flood the board in as few steps as possible.

Prepare a class and tester that simulates and tabulates the result of repeatedly throwing two dice.  Recall a dice, a six-sided cube with 1 through 6 dots on each side.

Using a now familiar looping user experience, the user enters the number of throws. Then, the system simulates the throws and displays the results using a frequency distribution chart. For instance:

Please, use this statement to get the dice action started!

String[] labels = {"Snake Eyes", "Ace Deuce", "Hard Four", "Fever Five", "Easy Six", "Natural Seven", "Easy Eight", "Nina", "Easy Ten", " Yo-leven", "Boxcars"};

Write Python code that checks if an existing variable letter is a lowercase vowel. If it is a, e, i, o, or u and print out "Yes, it is a lowercase vowel". If the letter is y, print out "The letter is a consonant". If the letter is anything else, print out "No, the letter is not a vowel".

(language python)

Write a python program that will ask the user to enter as many positive and negative numbers and this process will only stop when the last number entered is -999. Use a while loop for this purpose. Your program should compute three sums; the sum of all numbers, sum of all positive numbers, and the sum of all negative numbers and display them. It should also display the count of all numbers, count of all positive numbers, and count of all negative numbers. Finally, it should compute and display the average of all numbers, average of all positive numbers, and average of all negative numbers.

A program, or software, consists of a series of related instructions, organized for a common purpose, that tells the computer what tasks to perform and how to perform them. An application, or app, sometimes called application software, consists of programs designed to make users more productive and/or assist them with personal tasks. The purpose of this discussion is to talk about the applications you use for work, school and play and the license agreements you agreed to when using them.

1. List ALL the different type of network connections involved in the operations for each of the scenarios below. Provide an illustration for each of the scenarios.

Scenarios a. You have just bought a new mobile phone from an online shop. You have decided to take a few snapshots of your best friend and send them to the email account of a mutual friend across the country. b. You are driving around in an unfamiliar city and have just gotten lost. By using your mobile phone’s GPS system, you submit a request for driving directions from a nearby intersection to your destination.

2. Broadcast networks refer to networks such as LANs connected by a technology such as Ethernet. Broadcast networks, by nature, are multiaccess where all routers in a broadcast network can receive a single transmitted packet. Discuss the requirements or deficiencies of a network layer (OSI layer 3 and TCP/IP layer 2) in a broadcast network.

Variable trials refers to a list where each list item is another list of 3 integers between 0 and 9. Imagine each list of 3 integers is a combination of numbers of a lock. Further suppose the variable code refers to a list of three integers that is the correct combination of the lock.

Write a program which, assuming trials and code are already defined, prints out a character for each digit of each trial. Print Y if the digit in the trail matches the digit at the same position in the code. Print # if the digit in the trial does not match the digit at the same position in the code but appears elsewhere in the code. Print N if the digit of the trial does not match the digit in the code and the digit in the trial appears nowhere in the code. Print a newline after the characters after three numbers (for each trial).

Example, if trails = [[2,3,4], [5,5,5], [5,2,3]], and code = [2,3,5], the program output should be:

Y Y N

# # Y

# # #

Hint: the in and not in operators can be used to test whether an item appears in a list.
