The assignment: C++ program or Java

You need to use the following programming constructs/data structures on this assignment.

1. A structure named student which contains:  

a. int ID; student id;

b. last name; // as either array of char or a string

c. double GPA;   

2. An input file containing the information of at least 10 students.

3. An array of struct: read the student information from the input file into the array.

4. A stack: you can use the standard library template for the stack or you can write your own code for the different stack operations. The stack stores elements of type student.

5. Output file containing a duplicate of all output sent to the console.

What to do:

1. Read all students rows from the input file into an array.

2. Store the information about seven different students in the stack: This is intended to initialize the stack.

3. Generate a random number between 1 and 20.

4. If the randomly generated number is even, read one row from the array and store it (push it) into the stack.

5. If the randomly generated number is odd then check If the number is divisible by 3, if so ask the user if they want to quit.

6. If the user selects to continue or the odd number is not divisible by 3 then pop one element from the stack and send it to the output file.,

7. If the stack is not empty and you quit: it will display the number of the students left in the stack, and display the information of each student left in the stack.

8. If you choose to quit, and the stack is empty when a pop is needed, or the array is empty when a push is required then do the following:

a. Display on the console and send to the output file: “The reason for quitting”, how many elements are left on the stack when quitting, and the content of each student record found in the stack when quitting.

Case Study

Spring Breaks R Us Travel Service

Chapter 3 – Use Cases

Spring Breaks ‘R’ Us (SBRU), introduced in Chapter 2, includes many use cases that make up the functional requirements. Consider the following description of the Booking subsystem. A few weeks before Thanksgiving break, it is time to open the system to new bookings. Students usually want to browse through the resorts and do some planning. When a student or group of students wants to book a trip, the system allows it. Sometimes, a student needs to be added or dropped from the group or a group changes size and needs a different type of room. One month before the actual trip, it is time for the system to send out final payment requirement notices. Students cancel the booking or they pay their final bills. Students often want to look up their booking status and check on resort details. When they arrive at the resort, they need to check in; and when they leave, they need to check out.

Case Question:

1. Using the event decomposition technique for each event you identify in the description here, name the event, state the type of event, and name the resulting use case. Draw a use case diagram for these use cases
2. Consider the new Social Networking subsystem that SBRU is researching that was described in Chapter Identify all the actors who might use the subsystem. Think in terms of the user goal technique to identify as many use cases as you can think of that you would like to have in the system. SBRU is guessing you might want to join, send messages, and so forth, but there must be many interesting and useful things the system could do before, during, and after the trip. Draw a use case diagram for these use cases.

2. You are a public health nurse working in an elementary school in Hamilton, Ontario. You have seen a substantial increase in the number of children in your school presenting with Attention Deficit Disorder (ADD). You are interested in whether a new drug developed by a local drug company improves the ability of children with ADD to maintain attention. You obtain ethics approval to study the drug, informed consent from the parents of 24 fifth grade children with ADD, administer the drug to the 24 children, and administer a test to the children to determine their ability to maintain attention while performing a task. Scores are continuous, can range from 0 to 25 with higher scores reflecting a better ability to maintain attention, and you know from previous research that scores tend to be normally distributed. Six of these students receive a placebo containing none of the drug. Six students receive 2 mg of the drug, six students receive 4 mg of the drug, and six students receive 6 mg of the drug. The table below summarizes the results from your study. Use these data to answer the following questions. Assume α=0.05.

3. Placebo (0 mg)	Drug (2 mg)	Drug (4 mg)	Drug (6 mg)
   4	7	16	17
   7	8	14	18
   11	13	12	13
   11	6	11	17
   7	9	15	20
   10	9	13	15

4. a.You have one further prediction, and that is that children with ADD who receive the drug will perform significantly better than children with ADD who do not receive the drug. Conduct the appropriate test to confirm this prediction, if the results from question a support doing this additional testing. Are you able to confirm your prediction? Explain, including the calculations and/or SPSS output to support your answer. [2 Marks]

• The program reads a text file with student records (first name, last name and grade on each line) and determines their type (excellent or ok). <--- Completed
• Need help on this
• Then it prompts the user to enter a command, executes the command and loops. The commands are the following:
• • "all" - prints all student records (first name, last name, grade, type).
  • "excellent" - prints students with grade > 89.
  • "ok" - prints students with grade <= 89.
  • "end" - exits the loop the terminates the program.

Directions: For each of the following studies, state both the null and alternative hypotheses and the decision rule, then work the problem. Look up the critical value of t that would cut off the tails of the distribution. Note that each study specifies the alpha value to use and whether to use a one- or two-tailed test. Decide whether to reject or fail to reject the null and answer the question. Please copy and paste the text into a document and include your answers in bold font.

There is no sample size for the first example. I will take whatever I can get to help solve

1. Sommer (1999) investigated student satisfaction with distance learning. One group of students took Introductory Psychology over the Internet and another group took the course in the usual classroom lecture format. Students rated their satisfaction with the course on a scale from 1 (not at all satisfied) to 9 (extremely satisfied). Sommer found that students in the distance learning condition had an average satisfaction of 4.33, with a standard deviation of 2.94, whereas students in the classroom format reported a mean satisfaction of 6.67 and a standard deviation of 0.82. State your null hypothesis, use α = 0.05 for a nondirectional test, and report your critical value. Is there a difference between the groups?

2. Wilson (1999) studied impulse control in grade-school children. She studied 25 average third-graders and found a failure of impulse control 4.6 times per day, with a standard deviation of 2.1 times per day. Wilson also studied 36 third-graders diagnosed with ADHD and found that they showed failures of impulse control on average 7.2 times per day, with a standard deviation of 3.1. State your null hypothesis, use α = 0.01 for a directional test, and report your critical value. Do third-graders with ADHD have more trouble with impulse control?

in c++ you need to write a program that maintains the gradebook for a specific course. For each student registered in this course, the program keeps track of the student’s name, identification number (id), four exam grades, and final grade. The program performs several functionalities such as: enrolling a student in the course, dropping a student from the course, uploading student’s exam grades, displaying the grades of a specific student, displaying the grades of all students in the course, and printing grades summary information.
To do that, you need to create a structure, Student, that holds individual student’s details. The Student struct contains the following fields:
struct Student { string name; // student first and last name long id; // student identification number double grades[4]; // array holding four exam grades double finalGrade; // student final grade }
Then, in your main program, you need to:
- declare a vector of Student structs, named students, to hold the data for all the students enrolled in this course. - process a transaction file, “StudentsTrans.txt”. Each line in the file contains a specific command such as “enroll”, “display”, “drop”, “uploadGrades”, “searchByName”, and “printClassSummary”. The line also contains all necessary data to process the command. Each command must be implemented in a separate function. The commands are:

▪ Enroll StudentFirstName StudentLastName StudentID   

This command adds a new Student record (object) to the students’ vector. You should read the student details from the transaction file (StudentFirstName, StudentLastName, StudentID). Before creating a new object, you need to check for duplicate student entries (if an existing student has the same StudentID). If this student was not previously added to the students vector, you should add an entry for that student and its details at the end of the students’ vector. Make sure to concatenate StudentFirstName and StudentLastName into one student name and set all grades initially to zeros. You can simply use the push_back function to add a Student object to the end of the vector. You should also display a message that the student was successfully added to the vector. For example:

enroll Joe Garcia 432345673 Joe Garcia successfully added to students vector…

If this student already exists in the vector, you should not add the student again to the vector. You should also display an error message. For example:
enroll Amelia Perez 876007654 Student already enrolled in this class, can not enroll again

▪ Display

This command displays the details of all students registered in the course in a neat table format. Details include a student’s name, id, four individual exam grades, and the final grade. The final
grade is the average of the four exam scores. You should print decimal numbers with 2 digits of precision. A sample display is shown below:

Student    ID    Exam1 Exam2 Exam3 Exam4 Final Grade

-------------------------------------------------------------------------

Suzy Walter 876523067 87.50    85.00    88.00    81.00 85.38

Amelia Perez 876007654 62.00 70.00    71.50    80.00    70.88 …   
▪ SearchByName Keyword

This command searches and prints the records of all students whose first names, last names, or full names include or match Keyword. For example, if Keyword is “James”, you should display the following students:

searchByName James Student ID Exam1 Exam2 Exam3 Exam4 FinalGrade ------------------------------------------------------------------------ James Ducrest 123282345 62.00 67.00 63.00 70.00 66.25 James Didier 123456789 79.00 85.00 80.00 88.00 83.00

If no matching entry is found, you should display a message that this student is not enrolled in this course. For example:
searchByName Michel No such student exists

▪ Drop StudentID

This command drops a specific student (whose id is StudentID) from the course by removing its entry from the students’ vector. You should check if that student is enrolled in this class before trying to delete its entry. If so, pay attention that deleting could be from any entry in the vector and not necessarily the last record. You should also display a message that the student was successfully deleted from the vector. For example:

drop 982323146… Andrea Meyer successfully dropped from course
If no matching entry is found, you should display a message that this student does not exist. For example:
drop 012345634… No such student exists
▪ UploadGrades StudentID Grade1 Grade2 Grade3 Grade4

This command uploads the grades of a specific student to the corresponding entry in the students vector. The command specifies StudentID, which corresponds to the id of the student whose grades should be uploaded. The command also specifies the 4 individual exam grades for that student (Grade1 Grade2 Grade3 Grade4). You should search for the student whose id matches StudentID. If a match is found, you should update its grades array and display a message that the student’s grades were successfully uploaded. For example:   

uploadGrades 876523067 87.5 85 88 81 Suzy walter grades successfully uploaded

Otherwise, you should display a message that this student was not found. For example:

uploadGrades 999999999 60 90 70 80 no such student exists, grades can not be uploaded

▪ PrintClassSummary

This command prints summary information. This includes: the name of the student who took the highest final grade in this course, the name of the student who took the lowest final grade in this course, and the overall class average.
To test your code, you may create and process the following transaction file:
“StudentsTrans.txt”

enroll Joe Garcia 432345673

enroll Suzy Walter 876523067

enroll Amelia Perez 876007654

Notes in program and right format if possible, thanks. You can use any of the sorting searches like bubble or selection search or QuickSort since this is the section we are working on.

P.S This was the question I was given, I can't edit it to give more detail and I can't edit the outputs needed to have anything else because those are non editable and so are the given files.

Write a program in Java and run it in BlueJ according to the following specifications:

• The program reads a text file with student records (first name, last name and grade on each line) and determines their type (excellent or ok).
• Then it prompts the user to enter a command, executes the command and loops. The commands are the following:
• • "all" - prints all student records (first name, last name, grade, type).
  • "excellent" - prints students with grade > 89.
  • "ok" - prints students with grade <= 89.
  • "end" - exits the loop the terminates the program.

For example, if the input text file is students.txt and the user enters "all" the program prints the following:

John Smith 90 excellent

Barack Obama 95 excellent

Al Clark 80 ok

Sue Taylor 55 ok

Ann Miller 75 ok

George Bush 58 ok

John Miller 65 ok

If the user enters "excellent" the program prints the following:

John Smith 90 excellent

Barack Obama 95 excellent

If the user enters "ok" the program prints the following:

Al Clark 80 ok

Sue Taylor 55 ok

Ann Miller 75 ok

George Bush 58 ok

John Miller 65 ok

Requirements and restrictions:

• Use the Students.java, Excellent.java, and Ok.java classes from the course website and make the following modifications/additions:
• • Create an interface Student and implement it with classes Excellent and Ok to represent the excellent and ok students correspondingly.
  • Create an ArrayList and fill it with objects of classes Excellent and Ok to store all students from the file.
  • Use the ArrayList to print all, excellent and ok students. Use the instanceof operator to distinguish between excellent and ok objects.

/* ArrayList, Interfaces, Class Object and instanceof operator
*
Suggested exercises:
- Create an ArrayList and fill it with Excellent and Ok objects.
Use the instanceof operator and casting to print the array (calling the info() method).
- Create interface Student (with info() method) and modify classes Excellent and Ok to implement Student.
Define the ArrayList of type Student. Print the array. Is casting needed?

Many business students are familiar with the pressure to get internships or part-time jobs in their career field while in school. The surest route to the career track for many is to take on these limited-duration work assignments. Internships do give employers an easy way to size up potential applicants in a setting identical to the one in which they would perform. And unlike employees, interns are easily terminated if they don’t pan out. It’s the same situation for part-time or summer workers, who are sometimes let go at a moment’s notice. Internships are such a powerful tool for finding jobs that some students have begun to take on low-paid or even unpaid work assignments. While such “early bird” internships used to be primarily associated with large organizations, many startups have begun to attract students. For example, Remy Agamy took an internship at a three-person design company, knowing that it wasn’t likely to turn into a job. Still, in the job market she found that other prospective employers were keen on learning what she’d done in this internship. “I think we talked more about my eight-week internship than my four years of consulting experience,” she said. The value of internships for students, however, has long been questioned. While there may be a promise of a chance to learn, many students complain of doing little more than acting as unpaid, unskilled labor. Christina Isnardi is one student who felt exploited by the system. She described working 16- or 17-hour days at Lions Gate Entertainment, doing work like taking breakfast orders or working in locations far from the actual film set. “We just feel as though our dreams are holding us hostage to this unfair, unethical labor practice.” Isnardi’s experiences are not uncommon. Interns working for organizations as diverse as MTV, Warner Music Group, and Madison Square Garden describe similar experiences, which is why all these organizations have all faced lawsuits from former interns. In what might seem like a dream job, other students have negotiated great-sounding internships at organizations that regularly hire interns and pay them, but then don’t know what to do with these temporary employees. One student we know of was encouraged to make the best use of his time during his summer internship in a major city, including taking a paying job elsewhere and just staying in touch by phone when work hours overlapped! Because of his ingenuity, he reported it was a very productive summer, but the internship didn’t provide the learning opportunity he was seeking. Many major organizations maintain internship programs as part of a broader corporate social responsibility (CSR) value. Whether internships have value remains an open question. Most of the controversy does suggest that students need to know the details before agreeing to these arrangements, because not all internships offer a fair living wage or a strong career experience. HR departments are responsible for monitoring and designing internship programs. Question 1: Discuss the main concerns in the case. Why are these problems related to OB and HR? explain.

Question 2: As an upcoming employee student, what specific characteristics would you look for in an internship? Is there any form of good practice in intership at Lions Gate Entertainment? Discuss.

Question 3: In line with your answers in question 1, what are the recommendations you can offer? Be s[pecific with your answers.

Christina Isnardi is one student who felt exploited by the system. She described working 16- or 17-hour days at Lions Gate Entertainment, doing work like taking breakfast orders or working in locations far from the actual film set. “We just feel as though our dreams are holding us hostage to this unfair, unethical labor practice.” Isnardi’s experiences are not uncommon. Interns working for organizations as diverse as MTV, Warner Music Group, and Madison Square Garden describe similar experiences, which is why all these organizations have all faced lawsuits from former interns.

In what might seem like a dream job, other students have negotiated great-sounding internships at organizations that regularly hire interns and pay them, but then don’t know what to do with these temporary employees. One student we know of was encouraged to make the best use of his time during his summer internship in a major city, including taking a paying job elsewhere and just staying in touch by phone when work hours overlapped! Because of his ingenuity, he reported it was a very productive summer, but the internship didn’t provide the learning opportunity he was seeking. Many major organizations maintain internship programs as part of a broader corporate social responsibility (CSR) value.

Whether internships have value remains an open question. Most of the controversy does suggest that students need to know the details before agreeing to these arrangements, because not all internships offer a fair living wage or a strong career experience. HR departments are responsible for monitoring and designing internship programs.
