Step 1: Requirements

Write a program to do the following.  In main declare a Player Name Array and a Score Array.  Declare the size of the arrays to be 100.  In the InputData function input the player name and score into the arrays for an unknown number of players up to 100.  In the DisplayPlayerData function display the name and score of each player.  In the CalculateAverageScore function calculate the average score and return it by value.  In the DisplayBelowAverage function display the name of the player and score for any player who scored below the average.  Do not use global variables.   Output from Program:  Enter Player Name (Q to quit): Bob Enter score for Bob: 3245 Enter Player Name (Q to quit): Sue Enter score for Sue: 1098 Enter Player Name (Q to quit): Dave Enter score for Dave: 8219 Enter Player Name (Q to quit): Pat Enter score for Pat: 3217 Enter Player Name (Q to quit): Q    Name   Score Bob        3245 Sue        1098 Dave       8219 Pat        3217  Average Score: 3944.75  Players who scored below average    Name    Score Bob        3245 Sue        1098 Pat        3217 Press any key to continue . . .

Step 2: Processing Logic

Using the pseudo code below, write the code that will meet the requirements:   Main Function    Declare the player name and score arrays, number of players, and average score.     Call the InputData function    Call the DisplayPlayerData function    Call the CalculateAverageScore function and assign the returned value in average score    Call the DisplayBelowAverage function   InputData function     While the number of players is less than the length of the array         Prompt for the player's name         If the user entered Q, break out of the loop         Prompt the user for the player's score          Add 1 to the number of players     End-While  DisplayPlayerData function     Display the name and score of each player   CalculateAverageScore function     Add up the scores and divide by the number of scores to calculate the average score     Display the average score     Return the average score to main  DisplayBelowAverage function     Display the names and scores of all players who scored below the average score

Step 3: Create a new project

Create a new project and name it LAB5A.  Write your code using the Processing Logic in Part A Step 2.  Make sure you save your program.

Step 4: Compile and Execute

a)    Compile your program.  Eliminate all syntax errors.   b)    Build your program and verify the results of the program.  Make corrections to the program logic if necessary until the results of the program execution are what you expect.

Step 5: Print Screen Shots and Program

1.    Capture a screen print of your output [Do a PRINT SCREEN and paste into an MS Word document.] 2.    Copy your code and Paste it into the same MS Word document that contains the screen print of your output. 3.    Save the Word Document as Lab05A_LastName_FirstInitial

END OF PART A

 

   

Part B: Pig Latin

Step 1: Requirements

Write a program that will input a phrase and convert it to pig latin.  Put each word in a separate element of a string array.  Remove the first letter from each word and concatenate it to the end of the word followed by "ay".          Sample Output from Program:  *** You will be prompted to enter a string of  *** *** words. The string will be converted into   *** *** Pig Latin and the results displayed.       *** *** Enter as many strings as you would like.   ***  Enter a group of words or ENTER to quit: DeVry is a wonderful school  Original words: DeVry is a wonderful school New Words: eVryDay siay aay onderfulway choolsay  Enter a group of words or ENTER to quit: The Cowbows are going to the Superbowl  Original words: The Cowbows are going to the Superbowl New Words: heTay owbowsCay reaay oinggay otay hetay uperbowlSay  Enter a group of words or ENTER to quit:

Step 2: Processing Logic

Using the pseudo code below, write the code that will meet the requirements.   Main function     Display the heading     While the condition is true             Prompt the user for group of words or Enter to quit             Display original words             Call function pigLatinString( )     End while  pigLatinString( ) function     Declare and initialize string variables len, counter, start, begin, word and newString     While condition is true             Call find() and pass a space and start as parameters and return the returned value             to start             if start equals to string::npos             jump outside the loop permanently             call substr() function             display the word             update newString             increment start by one             assign start to begin    End While Call substr() Update newString Return newString

Project #2: Threads and semaphores
Due Date: 11:55PM, December 1, 2010
I. Project Organization
This project will study multiple thread programming, using semaphores and POSIX.
You should do the following pieces to complete your project. Each piece is explained below:
• Design 10 points
• Code 25 points
• Output 10 points
• Summary 5 points
Design
List each semaphore with its purpose and initial value. Provide pseudocode for each thread.
Code
Your code should be nicely formatted with plenty of comments. The code should be easy to read,
properly indented, employ good naming standards, good structure, and should correctly implement the
design.
Output
Output will be graded by running your program on the UNIX machines in Lab 244.
Summary
The summary section should discuss your simulation, any difficulties encountered, what was learned,
and results. It should be at least one page.
II. Project Description
You must complete this project based on POSIX.
This project simulates a game through multithreading. The following rules apply:
1. The main thread creates a server thread and two player threads.
2. A player thread is blocked until a server thread is created - the player thread cannot join a game
until the server thread is created.
3. Each game must have exactly two players -- the server thread cannot start the game until two
players join the game.
4. After the game starts, each player thread randomly generates an integer and passes this integer to
the server thread.
5. The server is waiting for randomly generated integers from two players.
6. The player threads wait for the result from the server.
7. The server thread compares integers and notifies two player threads the result (the thread which
generates a larger integer wins). Game ends.
Your output must show all activities in each thread.
For example:
Main thread creates the server thread.
Main thread creates the player thread 1.
Main thread creates the player thread 2.
Server threat starts.
Player thread 2 starts.
Player thread 1 starts.
Player thread 1 joins the game.
Player thread 2 joins the game.
Server thread starts the game.
Player thread 2 passes 123 to the server.
Player thread 1 passes 234 to the server.
Server announces player 1 wins the game.
GAME OVER.
III. Project Guidelines
Submitting
Submit your project on Blackboard. Include in your submission the following files:
1) A Word document for the written pieces of the project
2) Your source files
NO hardcopy submission. Late submission will NOT be accepted.
Cheating
All work must be your own. If cheating is detected, all parties involved will be given a zero for the project
and the penalty will be documented on a form that you must sign. You may be referred to the Dean's
office for further discussion.
Grading

case study assignment

Northeastern University (NEU) is now ranked among the top 100 research institutions in the United States.  This was not always the case.  As part of a methodical process and thanks to a significant investment of time, energy and money, the University reengineered its curriculum, improved the quality of its teaching and research faculty, built up its campus facilities, and rebranded itself.   Along the way, the institution could have misdirected its efforts and resources.  Fortunately, Northeastern’s leadership recognized the value of data-driven decision making.  Early on in the remaking of the University, NEU established a decision support system (DSS) to inform planning.    For example, in the early 1990’s, NEU stood firmly in the third tier of ranked U.S. Colleges and Universities, due in no small part to a student retention rate near 35%.  The University was determined to improve on this vital metric (today retention is closer to 85%), but to that end NEU needed to determine what factors/investments might substantial improve student retention rates.  By mining years of student cohort data, the University’s leadership determined those factors that influenced the student’s ability to stay at NEU through graduation.

The enabling information system, (i.e. the University’s first decision support system - DSS) drew on key University transaction systems for its data, including: the Registrar System, the Financial Aid System, the Human Resource System, and the Financial Management System.  Led by a technical team draw from the University’s Information Technology Services (ITS) Unit, a large cross-functional committee of stakeholders, including academic and administrative leaders from across campus, identified the data to be collected by the DSS and devised a common set of definitions, metadata standards and the like to ensure the quality and integrity of the data collection/translation process.  The IT team employed extract–transform-and-load (ETL) tools to draw the data from the aforementioned source systems and to load it into a specially designed data warehouse.  Rather than try to recreate data sets historically, the stakeholder committee agreed to start the DSS process and data collection with the most current body of transaction data, beginning with the Fall term of the 2002-2003 academic year.  The data warehouse now holds nearly nine full academic years of longitudinal data, including 36 data discrete sets as of Summer II term, 2010.

Once the data warehouse was fully deployed and once the automated procedures were in place to extract key data from the school’s various systems of record, the data warehouse was ready for use in decision support.   A team of analysts, working under the general direction of the Senior Vice President for Planning, mined this DSS data source looking for the underlying predictors of student retention and academic performance, tends in course registration and faculty and facilities utilization, demographic shifts in the student body, and many other high-level tactical and strategic issues facing the University’s leadership.  As the process added more academic terms of data to the data warehouse, the opportunities for richer and more focuses analysis became available to the DSS team.

To date the Northeastern University DSS has been used to inform the institutions policies and processes for delivering student services, to direct its building programs choices – especially regarding the construction of new student residents’ halls, and to focus faculty hiring and academic program development.  In turn these decisions have improved overall student satisfaction and retention, and school performance, vaulting NEU into the elite 100.

Question to Address:

1.      What technical components comprised NEU’s decision support system?

2.      Who were the key stakeholders in the process and why were they so important?

3.      To what would you attribute the DSS project’s success and how would you measure and assess outcomes?

4.      Without a DSS, how would NEU inform its decision making?  What are the shortfalls in these alternative approaches to decision making?
