Scenario:
Your team is given the project to design a database and associated interfaces for the ISE
department at North Carolina A&T State University to collect and manage the data collected
during each recruitment event. The database will store the information of prospective students
who attended some ISE recruitment event(s), and the information about recruitment events.
For each prospective student, the ISE department wants to collect his/her name (including last
name, first name and middle initial), gender, phone numbers (one or more), one email, and ethnic
group. The database generates a unique ID number for each prospective student. The required
information for each prospective student includes last name, first name, gender, email, and at
least one phone number. The optional information includes middle initial and ethnic group. The
seven pre-defined ethnic groups are White, Hispanic or Latino, Arian, Black or African
American, American Indian or Alaska Native, Native Hawaiian or other Pacific Islander, and
Other.
The ISE department wants to track the following information for each event: type, date, location
(including address, city, state and ZIP), and contact information (including a contact person’s
name, title, email and phone number). The database should generate a unique ID number for
each event. Except for event type, date and location, the other information is optional (refer to
Table 1 for pre-defined event types). More importantly, the database needs to track the participants of each recruitment event. One
prospective student can attend more than one event, and multiple students can attend one event.
The database also stores the classification of each student who attend an event (refer to Table 2
for a list of pre-defined classifications).

Weekly Reaction Paper, 2 pages

Each reaction papers should:

1.) Demonstrate that you have completed and understood the main themes of the week’s readings by summarizing the most significant ideas.

2.) Connect the readings’ themes to broader course themes, lectures, and other readings.

3.) Present your reaction to the readings, informed by course materials and your own experiences.

You have freedom in how you approach reaction papers, but here are a few suggestions:

• Compare and contrast the authors’ arguments in the week’s readings.
• Draw connections between the reading and your own experience or the experience of people you know.
• Discuss how you agree or disagree with the author’s point of view and why.
• Explain the strengths and weaknesses of the author’s argument.
• Describe why you find the author’s argument interesting, compelling, problematic, etc.
• Explain how the reading fits into our past or current discussions of urban society.
• Each reaction paper should contain the same basic information. It should begin with a thesis statement that communicates your focus (i.e. comparing and contrasting authors’ arguments, explaining how the readings are related to your personal experiences, etc.) Your thesis statement should tell the reader what you will be discussing. Your reaction paper should then contain a brief (one paragraph) summary of the main argument of each reading for that week. You should conclude with a 1-2 paragraph reaction to the readings that can take any approach, including the suggestions listed above.

In this project, you will write a C++ program to simulate some standard activities and operations that occur within a school system on a set of students in a COSC 113 class. The data below list the students currently registered to the class. There is a class size limit of 25 students. The information below should be stored in a file and then used as input for this project. THIS PROJECT SHOULD ONLY BE DONE USING CONCEPT COVERED IN CLASS. STRUCTS FOR STUDENT DATA STORAGE.

You are to create a Menu-driven program that runs continuously until the user of the program decides to stop the program. The program will read the input from a file, and output as requested to the screen. Use appropriate function calls where necessary to simplify your program. Your program should ensure the right data is entered, like 6 digits for the ID, and 10 digits for the Phone, not greater than 4.0 for GPA and so on. Phone number should be stored with string because it exceeds the limits of int, and does not require calculation. THIS IS AN INDIVIDUAL PROJECT

The project should contain at least the following functions (you can use more if you need to)

1. CreateClass – This is a function that reads the student info data above from the file into your appropriate data structure the student names should be in alphabetical order of last name (do not alter the input file). Your function should print the entire student info (best to call the print function for this), and show the current number of students in the class (class count).
2. RegisterClass – This is a function that allows a student to register for the COSC 113 class, by providing all the necessary information (first name, last name, major, studentID, GPA, PhoneNumber, HomeCity). The new student info should be placed into the correct position. Your function should then display the current class count. Note, if the class is full, it should prevent a new student from registering with an appropriate message. Print the list to show that your class is still sorted. Also your function should not be case sensitive.
3. DropClass – This is a function that provides a student the opportunity to drop the class. The student need only provide a unique information like their studentID or PhoneNumber. Your function should ask the student to provide any of the two. If the student is not registered for the class, display an appropriate message. Print the new class list to show the result of the drop and show the class count.
4. SortClass – This is a function to print out the class list in a sorted manner. The class can be sorted by Firstname, StudentID, HomeCity or GPA. Your function should ask the user for the sorting order they prefer and sort accordingly. You can choose to make this question into multiple functions for each sort, or one function. You are also free to use any of the sorting algorithms we covered. Print the sorted list.
5. UpdateInfo – This is a function that allows the student the opportunity to update any of their information that might have changed or was entered incorrectly. It should give the user the chance to select which information to update, and allow them update it, it should then ask if the user has anything else to update, if they do, it repeats if they don’t, print the new class list to reflect the updated data, and the class count.
6. PrintClass – This is a function that prints the entire student info in the class list, using the default sorting (by last name). It also displays the class count.
7. DisplayGPA – This is a function that takes from the user a certain GPA, and a choice, and displays the complete info of every student with GPA below or above that value depending on their choice. Also display a count for the number of students
8. DisplayBestMajor – This is a function that displays the name of the department with the highest average GPA for its students and the GPA average for the department. Also display a count for the number of students
9. DisplayDepartment – This is a function that takes from the user a certain Major, and displays the complete info of every student in that major. Also display a count for the number of students
10. DisplayState – This is a function that takes from the user a certain state, and displays the info of all the student from that state(e.g Maryland, Virginia). Also display a count for the number of students

SearchStudent – This is a function that given unique info like the studentID or Phone Number, it should be able to search the class list if the student is currently registered or not. If the student is registered, display their complete info. If not, display an appropriate message. You function should work for either an ID or a Phone Number.

DeansList – This is a function that prints out the entire info for any student who meets the requirement for being in the Dean’s List. Make the requirement a 3.7 GPA and above. Display a count for the number of students

BestStudent – This is a function that prints out the entire info of the student(s) with the highest G.P.A

WorstStudent – This is a function that prints out the entire info of the student(s) with the lowest GPA

ProbationList – This is a function that prints out the entire info for any student who meets the requirement for being on the probation list. Make the requirement a GPA of 1.0 or below. Display a count for the number of students.

DisplayStudent – This is a function that takes in a city from the user and displays the complete student info of all the students who do not belong to that city. Display a count for the number of students.

DisplayMajorCount– This is a function that takes in a choice from the user and based on the user’s choice prints the name and student count of the department with the highest or lowest number of students. If two departments have the same count, print both of them along with their count.

*************************************

here is what i have until now. and this is the next assignment.

Put all home works together and use methods to simplify code. Also expand to have preferences and budget for wall coverings the way that was done for floor options

Use separate Methods to calculate the change for area covered for each the Door, Window and Bookcase (Hint – you may want to use 2 methods for the book case effects since one is floor and other is wall). Also use method to determine floor covering option and wall covering option.

The user shall input the dimensions of the room and the eventual output will be how the walls and flooring is done and how much budget is left.

The user will input the number of doors, windows, and bookcases and the dimensions of each which will be used to adjust the total wall and floor space needed to be covered. The system will output the square feet of wall and floor after adjustments.

The user will be asked for his budget for the walls and if he has a preference for the type of material for the wall. The system will accept as input the costs for the different wall coverings and determine which wall covering the user can afford – being either his preference or the most expensive he can afford if he does not have a preference. It’s also possible the user can not afford any wall coverings. The budget left after the wall covering is kept for how much money is left.

The system will output the initial budget for walls, the selected option and cost of what the user can afford and what is left in the budget for walls.

The same process will work for floor coverings with the same output for flooring.

YOU also have COST OPTIONS FOR WALLS, A USER PREFERENCE AND A BUDGET, YOU WILL DO THE SAME FOR THE WALL as floors. SAME RULES APPLY – IF 0 THEN JUST PICK MOST EXPENSIVE, IF PREFERENCE GIVE PREFERENCE IF CAN AFFORD, IF NOT GIVE WHAT CAN AFFORD.

There are four options for wall cover (Ceramic Tile = 1; Paneling = 2, Wallpaper = 3; and paint = 4) each with a cost per square foot The program will ask for input and read in the budget in dollars and cents, the cost per square foot for each of the different wall options and also ask for which one the customer prefers where 0 means the customer does not care and 1-4 if they have a specific preference.

Output the users preference, their budget, if they got their preference, and what they did get. Also how much budget is left.

You will be graded on how well you map this to methods and how good the comments are explaining what the program does.

Use the following for data (it is the same as HW 3 so you should get the same selection answers for flooring as you get there.

For Flooring use:

Tile= $4.00 /sq ft; Wood = $3.00/ sq ft; Carpet = $2.00/ sq ft and linoleum = $1.00/sq ft).

Use the following as the budget and preference:

There are four options for wall cover (Ceramic Tile = 1; Paneling = 2, Wallpaper = 3; and paint = 4) each with a cost per square foot

For all three test renovation projects use Tile= $4.00 /sq ft; Paneling = $3.00/ sq ft; Wallpaper = $2.00/ sq ft and paint = $1.00/sq ft).

Use the following as the budget and preference:
