Instructions(C++)
A company hired 10 temporary workers who are paid hourly and you are given a data file that contains the last name of the employees, the number of hours each employee worked in a week, and the hourly pay rate of each employee. You are asked to write a program that computes each employee’s weekly pay and the average salary of all employees. The program then outputs the weekly pay of each employee, the average weekly pay, and the names of all the employees whose pay is greater than or equal to the average pay. If the number of hours worked in a week is more than 40, then the pay rate for the hours over 40 is 1.5 times the regular hourly rate.
Use two parallel arrays:
a one-dimensional array to store the names of all the employees (Name)
a two-dimensional array of 10 rows and 3 columns to store the number of hours an employee worked in a week (Hrs Worked), the hourly pay rate (Pay Rate), and the weekly pay (Salary).
Your program must contain at least the following…
(C++ Programming) You are given a file consisting of students’ names in the following form: lastName, firstName middleName. (Note that some students may not have a middle name.) Write a program that converts each name to the following form: firstName middleName lastName. Your program must read each student’s entire name into a variable and must contain a function that takes as input a string, consisting of a student’s name, and returns a string consisting of the altered name. • Use the string function find to find the index of , • the function length to find the length of the string • the function substr to extract the firstName, middleName and lastName. Output the altered name into a file. This program has no user interface.

You are given a file containing many words. Read in all of the words from the file and insert each word into a searchable ADT. Give the user a looping menu allowing them to search for words in the word list. Searches must be be found in O(1) or constant time. Your code must time the search operations, and display the time to the user.
For this assignment, you may use the provided word list or another word list with more than 150,000 words. Include this file with your submission.
You must design and implement the following classes:
Word: This class holds a single word as a string. Basic getters and setters are required.
HashTable: This class represents the hash table for storing many words.
Main: This is the driver class.
The driver:
Create a Hash Table
Read in all of the words from a text file into the Hash Table
Provide a looping menu for the user to perform searches.

- (C++ Language) Create a function that writes to a file named Inventy.txt the information of 8 items. Ask the user for the item's name, the item's quantity in storage, and the item's price and write it to the file. Create a function that reads the file and items' quantity and price to two different arrays. Create a function that computes the subtotal of each item. Implement all functions inside the main program and the computed value should be displayed with the item's name.arrow_forward(C Language) Given a set of text files containing synonyms for different words, complete the main program to output the synonyms for a specific word. Each text file contains synonyms for the word specified in the file’s name, and the synonyms within the file are grouped according to the synonyms' first letters, separated by an '*'. The program reads a word and a letter from the user and opens the text file associated with the input word. The program then stores the contents of the text file into a two-dimensional array of char* predefined in the program. Finally the program searches the array and outputs all the synonyms that begin with the input letter, one synonym per line, or a message if no synonyms that begin with the input letter are found.arrow_forward(C ONLY) The program expects the name of an input file and an output file to be given by the user. If the user does not input any names, default file names should be used, such as input.txt and output.txt.

Read the list of colleges into an array of structures. You may assume that the maximum size of a college name string is 64. The program should use either the insertion sort algorithm or the selection sort algorithm to sort the array in descending order by rank. Display any k consecutive schools requested by the user. For instance, if the user enters 12, the program displays the first 2 schools in a readable format of your choice. If the user enters 15, the program displays the first five schools, if the user enters 2 7, display 7 schools beginning with the one at index 1 (2 - 1), and so…arrow_forward
