C++ MUST MATCH OUTPUT IN PICS thank you for the help please match up In this lab, you're going to be working with partially filled arrays that are parallel with each other. That means that the row index in multiple arrays identifies different pieces of data for the same person. This is a simple payroll system that just calculates gross pay given a set of employees, hours worked for the week and hourly rate. Parallel Arrays First, you have to define several arrays in your main program employee names for each employee hourly pay rate for each employee total hours worked for each employee gross pay for each employee You can use a global SIZE of 50 to initialize these arrays Second, you will need a two dimension (2-D) array to record the hours worked each day for an employee. The number of rows for the 2-D array should be the same as the arrays above since each row corresponds to an employee. The number of columns represents days of the week (7 last I looked) Functions Needed In this…
your goal is to modify your assignment 6 program to allow the user to pick up a random item and display a sorted list of the contents of the knap sack. note: if you use the built in c++, the most you can make on this assignment is 4 out of 10. you are expected to right your own sort based on one of the algorithms covered in class. your program should have the following: • the name of the program should be assignment 6. • 3 comment lines (description of the program, author, and date). • modify your assignment 5 program to do the following: o display a menu (use a switch statement to implement the menu) of actions ▪ attack: • for now, just display that the user chose to attack ▪ pick up item: • randomly add one of 6 items to an array named knapsack o you get to choose the item names • display which item the user picked up ▪ add an option to the main switch statement: display knap sack contents • the contents of the knap sack must be sorted The knapsack items are bananas, lays,…
Your task for this assignment is to use the C++ standard library sort() function to sort numbersin an array.1. Use the sort() routine from the C++ standard library with an array to sort 10 randomnumbers. The program initializes an array with 10 random 2-digit integers (positive andnegative) using the rand() function. The program then sortsthe numbers in the array usingthe sort() function.2. The program displays on one line the original values in the array before the sort begins.After the sort, the program displays on one line the numbers in sorted order, lowest tohighest.3. Your C++ program is named csc231_prog4_yourlastname.cpp. Your C++ program containscomments starting on line 1 containing this information:a. the ID, section and name of the courseb. your namec. this file named. the program assignment number and due datee. the program purposeYou are always encouraged to add additional comments throughout the program that yourfeel might be helpful to the reader of your source code.4.…
in the C++ version please suppose to have a score corresponding with probabilities at the end and do not use the count[] function. Please explain the detail when coding. DO NOT USE ARRAY. The game of Pig The game of Pig is a dice game with simple rules: Two players race to reach 100 points. Each turn, a player repeatedly rolls a die until either a 1 ("pig") is rolled or the player holds and scores the sum of the rolls (i.e. the turn total). At any time during a player's turn, the player is faced with two decisions: roll - if the player rolls 1: the player scores nothing and it becomes the opponents turn. 2 - 6: the number is added to the player's turn total and the player's turn continues. hold - The turn total is added to the player's score and it becomes the opponent's turn. This game is a game of probability. Players can use their knowledge of probabilities to make an educated game decision. Assignment specifications Hold-at-20 means that the player will choose to roll…

Project Description The Lo Shu Magic Square is a grid with 3 rows and 3 columns shown below Write a program that simulates a magic square using 3 one dimensional parallel arrays of integer type. Each one the arrays corresponds to a row of the magic square. The program asks the user to enter the values of the magic square row by row and informs the user if the grid is a magic square or not. ----------------------------------------------------------------- the code template is as follows ---------------------------------------------- #include<iostream> using namespace std; // Global constants const int ROWS = 3; // The number of rows in the array const int COLS = 3; // The number of columns in the array const int MIN = 1; // The value of the smallest number const int MAX = 9; // The value of the largest number // Function…
This is for C++ Design an application that uses three identical arrays of at least 20 integers. It should call each module on a different array, and display the number of swaps made by each algorithm. 8 Sorting Benchmarks (bubble, selection & insertion sort) The following represents the output from 3 separate files: BubbleSort, SelectSort and InsertionSort. Don't ask the user to enter any numbers, but 'hard code' the values in the "Original order" as shown. Original order:26 45 56 12 78 74 39 22 5 90 87 32 28 11 93 62 79 53 22 51Bubble Sorted:5 11 12 22 22 26 28 32 39 45 51 53 56 62 74 78 79 87 90 93Number of location swaps: 89 Original order:26 45 56 12 78 74 39 22 5 90 87 32 28 11 93 62 79 53 22 51Selection Sorted:5 11 12 22 22 26 28 32 39 45 51 53 56 62 74 78 79 87 90 93Number of location swaps: 19 Original order:26 45 56 12 78 74 39 22 5 90 87 32 28 11 93 62 79 53 22 51Insertion Sorted:5 11 12 22 22 26 28 32 39 45 51 53 56 62 74 78 79 87 90 93Number of location…
In this lab, you use what you have learned about parallel arrays to complete a partially completed C++ program. The program should: Either print the name and price for a coffee add-in from the Jumpin’ Jive Coffee Shop Or it should print the message Sorry, we do not carry that. Read the problem description carefully before you begin. The file provided for this lab includes the necessary variable declarations and input statements. You need to write the part of the program that searches for the name of the coffee add-in(s) and either prints the name and price of the add-in or prints the error message if the add-in is not found. Comments in the code tell you where to write your statements. Instructions Study the prewritten code to make sure you understand it. Write the code that searches the array for the name of the add-in ordered by the customer. Write the code that prints the name and price of the add-in or the error message, and then write the code that prints the cost of the total…
