- ReadInstructor. The class will: – Create an array of instructor objects – Read the instructors.txt file – Create an Instructor object for each line of input and store the object in the array. – After closing the file, it will print out a line for each instructor in the array.

Many abbreviations are in common use but are not appropriate for formal communication. Suppose the abbreviations are stored, one to a line, in a text file named abbreviations.txt. For example, the file might contains these lines: lol :) free iirc 4 u ttfn Write a class AbreviationMarker that will read a message from another text file and surround each occurrence of an abbreviation(ignoring case) with <> brackets. Write the marked message to a new text file. For example, if the message to be scanned is: Ttfn, how are u today? Iirc, this is your first free day. Hope you are having fun! :) the new text file should contain: <Ttfn>, how are <u> today? <Iirc>, this is your first <free> day.

The "rating" should be from 1 to 5 (5 being the best). Add the appropriate member functions of the class (setters and getters). Continue to use the get_title_upper() function as part of the class, Game, and in the output within the main file, Game_List.cpp. Add the Default Constructor for the class with the member functions of the class. Ignore the Destructor code for now. It's there to show you where it ends up in future code. Don't forget to add the include guard to the .h file Use the scope resolution operator correctly for each file. Don't use the "using namespace std;" for the main…
- Java Problem The teacher at a school needs help grading an exam with a number of True/False questions. The students’ IDs and test answers are stored in a file. The first entry of the file contains the answer to the test in the form: TTFTFTTTFTFTFFTTFTTF Every other entry in the file is the student’s ID, followed by a blank, followed by the students’ response. For instance, the entry: ABC54102 T FTFTFTTTFTTFTTF TF The student’s ID is ABC54102, answer to question 1 is True, the answer to question 3 is False. Also, the student did not answer question 2 and question 18. The exam has 20 questions. Here is the grading policy: each correct answer is awarded two points, each wrong answer get -1 point, and no answer gets 0 point. Write a program that processes the test data. The output should be the student’s ID, followed by the answers, followed by the test score (total points), followed by the test grade. Assume the following grade scale will be used: 90%-100%, A; 80%-89.99%, B; 70%-79.99%,…for c++ please need three files employee.h productionWorker.h cpp file NB: NEED ANSWER THE EXCEPTION PROJECT. here is chapter 15 required 15, Employee and ProductionWorker Classes Design a class named Employee.

VideoNote Solving the Employee and ProductionWorker Classes Problem Programming Challenges 963 Next, write a class named ProductionWorker that is derived from the Employee class. The ProductionWorker class should have member variables to hold the following information: • Shift (an integer) • Hourly pay rate (a double ) The workday is divided into two shifts: day and night. The shift variable will hold an integer value representing the shift that the employee works. The day shift is shift 1, and the night shift is shift 2.

The class functions: Size: Returns the file sizeName: Returns the file nameRaw: Returns the unparsed raw dataParse: A external function to Parse the data. The function accepts the raw data and returns the data parsed by the function. This type of function is called a "Call-Back Function".

- CSC 220: Word Unscrambler Game Use Java programming. Design and implement a word unscrambler game in Java. Your program should read in a random word from a file called words.txt(note the lack of capitalization) that you provide.The words.txtfile will beplacedin the same folder with your Java program.The file should contain one word per line andcontain at least 10 different words. To read a random word you can generate a random number between 1 and the number of lines, and skip n-1 lines before reading the word. Scramble the word by swapping random pairs of letters a random number of times(mandatory use of a loop). Display the scrambled word with character indices on top. Offer the user a menu with the following choices: Enter 1 to swap a pair of letters: If this option is selected prompt the user to enter two indices and swapthe letters. A space should separate the two indices. Print an error message if the indices are invalid. If the word is unscrambled successfully print a…JAVA PROGRAM Chapter 4.

- in c++ Write a function named createTwoNames that will do the following: - Read in a word and its definition - Create the Word object for that word and definition - Read in an item’s name and its price - Create the Item object for that item - It will return an array of two pointers pointing to these newly created Word and Item objects. It will use try-catch statement to handle the exception. If the user enters an empty or all-blank word or definition or item’s name, it will not create the object(s) and return null for that object only. In another words, it may create 0, 1 or 2 objects. Whenever the error occurs, it must print out the correct error reason: empty or blank (but not both).
