Updated 3/29 with project grading %s CS 3377 Project The goal: create several versions of a process that updates and saves a binary file as a new file. The Setup This project will be done in 4 parts. To keep them separate, I implemented a factory pattern so that you (and the autograder) can test each copying method separately. It will look like this: FileModifierFactory: creates 1. Part1SimpleFileModifier: fill in during part 1 2. Part2MultiProcessModifier: fill in during part 2 3. Part3ThreadedModifier: fill in during part 3 4. Part4SocketModifier: fill in during part 4 You will be given (and not need to modify): 1. main.cpp. Launches the appropriate test based on the arguments 2. Util.cpp/h. Includes some useful attributes. 3. FileModifierFactory.cpp & .h. These build the proper PartXModifier based on the argument. 4. PipeCopier.cpp & .h. Helps you with the pipe for part 2. While each part will be tested separately, you are encouraged to reuse code as much of it will be useful for multiple parts. The File The file you are to read, modify, and save is a binary file that contains a sales list. A binary file is a non-text file, meaning some things (like numbers) aren’t stored as digits but as the ints/floats you use as variables. The name of the files to read and write will be in Util.h. The file will be structured like this: Field Size Type Purpose HEADER NumEntries 4 bytes Integer Tells you how many entries you need to read ENTRY (repeated NumEntries times) Date/Time sizeof(time_t) Time Timestamp (# seconds since 1/1/1970) Item ID Sizeof(int) Integer Item’s code Item Name 50 bytes char* Name of the item sold Item Quantity Sizeof(int) Integer Number sold Item Price Sizeof(float) Float Price of the products What You’ll Do In each part, the goal is to copy the file, adding two additional sales: 1. The Sobell book: a. Time 1612195200 (2/1/2020 4 PM GMT) b. ID 4636152 c. Name “A Programming Guide to Linux Commands, Editors, and Shell Programming by Sobell” [warning: this is more than 49 characters, so you have to truncate it—I say 49 because you need a null terminator] d. Quantity: 70 e. Price: 70.99 2. The Advanced Programming book a. Time 1613412000 (2/15/2020 6 PM GMT) b. ID 6530927 c. Name “Advanced Programming in the UNIX Environment by Stevens and Rago” [warning: more than 49 characters again] d. Quantity: 68 e. Price: 89.99 Be sure to update the total number of entries to account for these new ones. Part 1 (Due 3/29, worth 20%) You will read in the file (Util::inputFileName), add the two entries, and save the file (Util::outputFileName) using open(), close(), read(), and write(). You must use the low-level functions we will talk about in APUE chapter 3 (open, close, read, write). Failure to do so will result in 0 points for this part of the project. It is highly recommended that you do the file reading and writing in class(es) outside Part1SimpleFileModifier, as that code will be useful later. Part 2 (Due 4/12, worth 20%) In this case you will spawn a new process using fork() and exec(), and split the responsibilities like this: 1. The original process will read the file (2nd argument=2) and then write the data over a pipe to the child process. 2. The child process will read the file from the pipe (which will be set to standard input) and write the data to the output file. 3. PipeMaker will take care of the pipe setup for you: a. Create PipeMaker before the fork. b. In the parent process, call setUpToWrite() to ready this process for writing. You’ll get back the file descriptor to write to. Write the file data to that file descriptor (hint: it’s just like writing to a file). c. In the child process, before execing, call setUpToRead() to dup the pipe output to standard input. You can then exec the process (21S_CS3377_Project) with the write option (2nd argument=3), read the data from standard input (just a file descriptor, remember!), and write to the output file. d. Either the parent or the child process can do the update (but not both, obviously). When calling exec, use the command 21S_CS3377_Project 2 3. This will trigger main to give you the proper setup for the child process. You will be responsible for spotting the Util::IOType of WRITE (3), and read from standard input rather than the input file. Part 3 (Due 4/26, worth 30%) In this part you will create a thread and pass the file data from one thread to the other. The threads will be like this: 1. Main thread: read the data, create the thread, and pass the data along 2. Created thread: receive the data and output it to the file I did all of this inside of Part3ThreadedModifier. Create a mutex and condition for both threads to share, and pass a pointer to the Part3ThreadedModifier object to pthread_create (and read it in the other thread). Then you can use the shared mutex and condition to coordinate passing the data. The easiest way to pass the data is to use a variable inside Part3ThreadedModifier (type EntryInfo). The main thread should lock the mutex before creating the receiving thread (and the receiving thread should attempt to lock the mutex right after it starts up) to ensure the proper ordering. Then do a loop in each thread like this: Main (sending) thread Receiving thread Wait on shared condition (for writing thread to be ready) Signal condition to say we’re ready Wait on condition (for an entry to be ready) Update the variable with the next entry Signal the condition Loop around and wait on the condition again Retrieve the info, save it for later writing Loop around and signal the condition again Once you’ve passed all the entries (5 or 7 depending on where you want to add the new ones), unlock the mutex on both sides. Part 4 (Due 5/10, worth 30%) Here you will use two processes again, this time with a socket connecting them. A port number to use (12345) is at Util::portNumber. • Note: if you get an error that the port is already in use, it’s likely because you just ran the project and the operating system hasn’t released the port yet. You can either wait a bit (a few minutes at most) or change the port number (12346, etc.). When I did this step, I reversed the setup from part 2: the main process here reads from the socket (writing to the output file) and the spawned process writes to the socket (reading from the input file). Again, it is up to you where you want to add the two new entries. When you spawn the 2nd process, use 21S_CS3377_Project 4 3. After the fork, the socket reading process (parent process for me) creates a socket and listens on that socket using the port number above. The socket writing process (child process for me) creates a socket and connects to the listen socket. Depending on the timing of things the listen socket may not be ready the first time; here is code to repeatedly wait for the listen socket to be available: int amountToWait = 1; while ( connect(fileDescriptor, (struct sockaddr*) &serverAddress, sizeof(serverAddress))) {  if ( errno != ECONNREFUSED) {  // Something unexpected happened  throw FileModifyException(“Error connecting”);  }  std::cout << "Not ready to connect yet...n";  // Exponential backoff  sleep(amountToWait);  amountToWait = amountToWait * 2; } Once the connection is made (reader gets back a file descriptor from accept() and the writer gets out of the loop above) you can transfer the data. Remember that a socket is just a file descriptor, so your code to write/read from earlier parts will work here, too.

Project Description:

In this project, you will create database objects to track the  construction projects and the events related to the projects at a  college. You will create a table and import data from Excel to create a  second table. You will use a database template to enter data into the  Events table. You will create a simple query, a form, and a report.

Start Access. Open the file Student_Access_1G_College_Construction_HW.accdb downloaded with   this project. Close the Event List multiple-items form that automatically   opened. Open the Navigation Pane.

In   Datasheet view, create a new table. Beginning in the second  column of the   table and using the data type of Short Text, create the Building Project, Site,   and Contractor fields (in that order). In the fifth   column, using the Currency data type, create the Budget Amount   field.

Change   the data type of the ID field to Short Text, rename the ID field to Project ID and change the Field Size to 5

Starting   in the Project ID field, add the following three records to the new table:

P-356

Student Center,     3-story

Northeast Campus

RR Construction

61450000

P-823

Student Center,     2-story

Southeast Campus

RR Construction

41960000

P-157

Health Professions     Center

Northwest Campus

Marshall Ellis     Construction

42630000

Save   the table as 1G Projects, and then close the table.

Append   the records from the downloaded Excel file a01G_Projects.xlsx to the 1G Projects table.

In   the Navigation Pane, organize the objects by Tables and Related  Views. Open   the 1G Projects table (the table has eight records). Close  the Navigation Pane.

Switch   the 1G Projects table to Design view. For the Project ID field, enter a   description of Enter the Project ID   using the format P-### For the Site field, enter a description of Campus Location.   Save the table.

Switch   to Datasheet view, apply Best Fit to all of the fields in the table, save the   table, and then close the table.

Import   the records from the downloaded Excel file   a01G_Contractors.xlsx into the database as a new table named 1G Contractors. Designate the first row as column   headings and the CO ID field as the primary key.

Open   the 1G Contractors table in Datasheet view (the table has four  records).   Apply Best Fit to all of the fields in the table, save the  table, and then   close the table.

   Based on your 1G Projects table, use the Query Wizard to create a  simple   query. Add the Site, Building Project, and Budget Amount fields  (in that   order). Keep the default name of 1G   Projects Query, click Finish to display the query results, and then close   the query.

Based   on your 1G Projects table, use the Form tool to create a form for the table.   Save the form as 1G Project Form, display the form in Form view, and   then close the form.

Based   on your 1G Projects table, use the Report tool to create a  report. Delete the   Budget Amount field from the report. Save the  report as 1G Projects Report.

Sort   the Building Project field in ascending order. Set the width  of the Building   Project, Site, and Contractor fields to 2 inches.  Delete the page number from   the report, save the report, and then  close the report.

Open   the Navigation Pane, open the Event List form, and then close  the Navigation   Pane. In the Event List multiple-items form, enter the  following two records   (the Start Time and End Time data will reformat  automatically):
 

  Title: Groundbreaking Start Time: 6/13/22 10a End Time: 6/13/22 11a Description:   Student Center groundbreaking   Location: Northeast Campus
   Title: Dedication Start Time: 8/26/22 12:30p End Time: 8/26/22 2p
   Description: Gymnasium building   dedication   Location: Southwest Campus

In   the Event List form, click New Event, and in the Event Details  single-record   form, enter the following record (the Start Time and End  Time data will   reformat automatically):
 

  Title: Community Arts Expo Start Time: 10/5/22 6p
   End Time: 10/5/22 9p   Description: Book and Art Expo at   Library   Location: Southeast Campus 

You are in charge of managing a local softball team, one in which there is a lot of turnover. While you have a couple of regulars, much of the team members come and go frequently. When it comes to organizing games, it is becoming more and more difficult to keep track of the current members, so you decide to write a small program to help you track the current players.Write a modularized program that will utilize a main menu to control the program’s functions and a list to store the members of your team. The following functions that your program needs to include:Print the current member list.
Add a new member.
Remove a member.
Modify an existing member.
Exit the program
Remember that you can create a function using ‘def.’ In other words, for adding a new member, you will need a function similar to: ***** *****

 Respond to the discussion about algorithms and their roles below using 150 words or more. 

At  the most basic level, an algorithm is simply a set of step-by-step  instructions that we utilize to accomplish a specific task. We use  algorithms every single day in our day-to-day activities: Brushing our  teeth, getting dressed, driving to work, making dinner. These daily  tasks which we complete are all composed of a set of instructions that  starts with a certain action and ends with a certain action.

In  the realm of computer programming, algorithms are utilized to enhance  the efficiency, effectiveness, and functionality of the programs we  create. Two such types of algorithms are searching algorithms and  sorting algorithms.

Sorting  algorithms are designed to sort an array of objects into a specific  order. Searching algorithms are designed to compare the elements of an  array to find a particular value within an array of objects. Just a few  examples are search engines, the sorting of a business’ online item  inventory, and sorting/searching a database of students who attend a  university.

There  are multiple approaches which people have taken to solve the issue of  sorting and searching an array of items. Two frequently used searching  algorithms are linear search and binary search. Three frequently used  sorting algorithms are insertion sort, selection sort, and bubble sort.

Each  of these types of algorithms have both pros and cons associated with  them. The main properties that we want to keep an eye on when choosing  an algorithm are memory usage, maintainability, and time complexity. It  is always best to assess the situation and to use discretion when  choosing which algorithm that we want to implement into our program.

Instructions:

1. Create a program that will model a music playlist by using an ArrayList that holds Song objects.
2. Using jGRASP, write a Java program named LastnameFirstname14.java, using your last name and your first name, that does the following:
   • Uses an ArrayList to model a music playlist.
   • Uses Song objects to represent songs in the playlist, with the following instance variables:
     • Title
     • Artist
     • Minutes
     • Seconds
     • Note: Your toString should print minutes and seconds together (see possible examples below in the Expected Output section)
   • Create a method called createPlaylist. Create an ArrayList of at least 5 songs of your choice. Return the ArrayList.
   • Create a method called editPlaylist. An ArrayList of Song objects will be passed to this method. In this method, ask the user if they would like to add or remove a song to the playlist, or if they change their mind and don’t want to add/remove any songs.
     • If they choose to add a song, ask them for the song information. Create a Song object and add it to the ArrayList.
     • If they choose to remove a song, print out the ArrayList in a readable format — in other words, don’t just use “System.out.println(playlist);” (see below for Example Output).
     • If they change their mind and do not want to add/remove a song, don’t change anything.
     • Return the ArrayList.
     • Note: I recommend you use a loop here so that the user can add/remove as many songs as they like. This makes for a better, more useful program, but it is not required for this assignment.
   • Create a method called savePlaylist. This playlist will have two parameters: the ArrayList and an indicator for whether the user would like to append to or overwrite a file. In the file, record the date that the playlist was saved, then write the ArrayList information to the file in a readable format — in other words, don’t just use “System.out.println(playlist);”. Confirm to the user that the file was successfully saved, and print the filename or filepath.
   • In the main method:
     • Call the createPlaylist method, then print the returned ArrayList. Make sure to print it out in a readable format — in other words, don’t just use “System.out.println(playlist);” (see below for Example Output).
     • Ask the user if they would like to edit your playlist. If so, call the editPlaylist method and print the returned ArrayList.
     • Ask the user if they would like to save the playlist. If so, call the savePlaylist method.
3. Your program MUST:
   • Create at least 5 Song objects, all with valid data
   • Store the Song objects in an ArrayList
   • Use the printPlaylist method to write out the data for all Song objects in your ArrayList to a separate text file in a neatly arranged format.
   • Actively use in-line comments stating what each section of code does.
   • Use try/catch if, and only if, necessary.
4. Your program must conform to the Java coding standards reviewed in class during Week 3.
5. Your program should not use code/concepts we have not yet covered. You must demonstrate that you have mastered the concepts covered in class.
6. Remember to always begin your code with the following documentation comments:

/**

 * Short description of the program.

 * 

 * @author     Last Name, First Name

 * @assignment ICS 111 Assignment XX

 * @date       Today's Date

 * @bugs       Short description of bugs in the program, if any.

 */

Expected Output:

You may format your toString any way you want, as long as it presents the song info in a readable manner. Here are some suggestions:

“Say So” by Doja Cat (3:58)

“South” by Galimatias
3 minutes 35 seconds

Title:  “Fly – FKJ Remix”
Artist: June Marieezy, FKJ
Time:   4:12

Feel free to choose one of these formats, or make up your own!

The following example uses the 1st format. The example also adds in the option to allow the user to continuously add/remove songs until they choose to stop, and to specify where in the playlist they’d like to add a song. These  two features are optional.
