C++ PLEASE MATCH OUTPUT IN PICS (Previous answers were incorrect) 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,…
attached is sample output needed to complete this C++ assignment. Function definitions needed with the //. please do not use 2d arrays either. 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…
I can both pass and return an array value from a function. Group of answer choices: True False this is for c++
Python (this is not graded this is practice work that is not graded) write and test a function which takes two dates (month, day) list arguments.When the function is called with the two arguments, it returns the number of days betweenthose two dates. Print the returned value. It is assumed that the first date occurs first. Forinstance, if the users calls the function with FUNCTION([12, 10], [12, 20]) as arguments, thereturned value is 10 days. However, if FUNCTION([12, 20], [12, 10]) is called, the returnedvalue is -10 days.Assume February has 28 days.Test data: [10, 30], [5, 20] [1, 30], [5, 25] [5, 25], [1, 30] [1, 1], [12, 31]
