Asks the user "How many parrots do you own?"

        2: Reads in that many single word names (one for each parrots) from the user and stores the names in an array.

        3: After the user has finished entering names, the program should display the list of all the parrots the user entered.

        4: then display the parrots  in alphabetical order for part 3. Note: string objects can be compared with the “<” operator, which will determine if a given string is alphabetically less than another string.

You may assume the user will own at most 50 parrots.

c++

In C++ write an application that calculates total retail values for 5 different shoes entered by the user.

Shoe 1 $15.50
Shoe 2 $27.30
Shoe 3 $34.50
Shoe 4 $42.11
Shoe 5 $54.25

Application must read shoe number and quantity sold for each transaction stdin, compute the total value of that sale, and add the value of that sale to a grand total for that shoe. After all data has been entered, display the total value of each of the five shoe items. Must have driver and a class, must use a switch structure to which shoes sales to update, must use a sentinel controlled loop to determine when the program should stop looping and display result.
Data members
Product price
Total sales for product(in dollars)
Member Functions
One 1 argument constructor(representing the shoe price), set the value of the data member using this argument. Getters and setters for data member, and updateTotalSales method(uses one parameter representing quantity sold and does not return a value) . must use getter and setter methods to access the fields do not access them directly. It computes the total value of the current sale by multiplying the argument passed by the shoess price. It updates the shoes total Sales data member by adding the value calculated in the previous step to the shoes existing totalSales. Must use getter and setter functions. Do not access the data members directly.

Main function
Instantiate 5 separate objects of the class Shoe, passing the appropriate argument to each constructor. The Shoe class constructor requires the price of that instance of the shoe. The prices can be hard coded numbers.
Using Sentinel controlled loop
1.   Read the shoe number and the quantity sold for one transaction.
2.   Use a switch statement to determine which Shoe objects sales to update.
3.   Call the appropriate Shoe objects updateTotalSales function.
4.   Continue loop until user enters 0 for the shoe number.
5.   After the loop is complete display each shoe objects total sales, including the dollar sign, two decimal places with a field width of 10.

Sample run
Shoe number: 2
Quantity sold: 4
Shoe number: 1
Quantity sold: 3
Shoe Number: 5
Quantity sold: 2
Shoe number: 1
Quantity sold: 2
Shoe number: 5
Quantity sold: 3
Shoe Number: 4
Quantity sold: 2
Shoe Number: 0

Total Sales
Shoe 1 : $77.50
Shoe 2: $109.20
Shoe 3: $0
Shoe 4: $84.22
Shoe 5: $271.25

IN JAVA LANGUAGE

Linked List-Based Stack Implementation

Implement Stack using a Linked List

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

Instead of using an array, as the StackLab did, here you will use a Linked List from your language's library. Implement all the methods of Stack : push(), pop(), size(), printStackDown(), 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 stack was array, now the underlying implementation of stack will be Linked list.

IN JAVA LANGUAGE

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.
