- Please use C++. Also, you don't need a header file, just a CPP File. Please make sure the output is exact.arrow_forwardWrite a C++ program : Question:Ask user to give you a list of the numbers and then Sort them, by calling two functions: Asc(Sort in Ascending order), and Desc(Sort in Descending order): Do the above question by using array.

- Write a C++ program that helps the user plan out their budget. It should ask the user for the most recent 5 things that they bought; it should ask for both the name for the item and its price. Then, print out the following: total money spent, average money spent per item, lowest priced item, and highest priced item. You can assume that each item has a different name and a different price. You must use at least 1 array and you must display all numbers as dollar values (exactly 2 places after the decimal) EXPECTED OUTPUT Welcome to the Budget Helper. What are the last 5 things you bought? Item 1 name: Bananas Item 1 price: 1.5 Item 2 name: Shoes Item 2 price: 45 Item 3 name: Coffee Item 3 price: 2.5 Item 4 name: Metrocard Item 4 price: 120 Item 5 name: Jacket Item 5 price: 89 The total amount you spent is 258ドルThe average price per item is 51ドル.60The cheapest item is BananasThe most expensive item is Jacketarrow_forwardC++ 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 lab, you must read in the employee names first because this...arrow_forwardhelp with c++...paste indented code plzz Q3: Ask user enter size of array N, then ask user enter maximum number of array element X, then create an array size N, and assign each element of array to random number between 1~X. Print the array, and also find which element appeared most in the array, print all if there are multiple elements which are most at the same time. Sample input: Enter N: 20 Enter X: 10 Sample output: 8 7 10 8 1 7 4 3 4 7 5 6 4 3 1 10 1 9 9 10 1 4 7 appear mostarrow_forward
- C++arrow_forwardThe Lo Shu Magic Square is a grid with 3 rows and 3 columns shown below. The Lo Shu Magic Square has the following properties: The grid contains the numbers 1 – 9 exactly The sum of each row, each column and each diagonal all add up to the same number. This is shown below: Write a program that simulates a magic square using 3 one dimensional parallel arrays of integer type. Do not use two-dimensional array. 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. Processing Requirements - c++ Use the following template to start your project: #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 //...arrow_forward
