CASE STUDY - PAYROLL SYSTEM PHASE 5: ARRAY

The purpose of this phase is to expand the payroll system to display all employee information in a tabular form by including arrays.
A)  Display company title and a header that labels the output in a tabular form.  Input the first name and last name of an employee.

char firstname[10], lastname[15];
Hint: You may want to use the following I/O manipulators.

#include <iomanip.h>, setw(15), setprecision(2) setiosflags(ios::fixed|ios::showpoint|ios::left)

B) Convert the program as it is to arrays. Set maxsize of array to 100.          

int  hw[100],empid[100];

C) Take advantage of arrays by breaking programs into separate units. Each unit should have a separate loop.

·         Read all data into arrays.

·         Compute all the overtimepays.

·         Compute all the grosspays.

·         Compute all the taxrates.

·         Compute all the netpays.

·         Display all the arrays.

D) Include a search by employee id. (An extra-credit)

E) Include a search by employee name. (An extra-credit)

F) Sort the data either by employee id or by employee name.

The nice thing about an array is that as soon as you read the data in it, you can always go back and look at it using a loop.  Therefore loop and array are "FRIENDS".  There is one problem with an array, if you shut down the computer it is erased.  If you create a file and shut down the computer, it will be saved.  Array is faster.  RAM=Random Access Memory.  Part C is one loop to read the array, one loop to computer overtimepay, one loop to compute grosspays, one loop to computer taxrate, one loop to computer netpays.  When you do thte payroll program.  It is not one individual programmer.  How many programmers do you need for payroll program.  THOUSANDS!  Therefore you must work as a team and take responsibility.  Functions will help you to modularize programs into smaller units so that you can work with a team.  The program you are learning to be done alone, really is not one persons work.  It is hundreds.  It is many peoples efforts.  If the information is one loop and one statement in any program you make. 

STORY: 1  One my students used this and made a job for himself.  Lets say Sears has 10,000 flyers to mail out.  If you sort your zip code a certain way your postage is not 37 cents.  You can get 30 cents per mail if you sort it correctly.

STORY 2:  I was working at NYU and one of the faculty came to me and doesn't know why in this program this one guy whose starts with Z comes up on top.  Zalowski.  I told him to delete his name he deleted it and the problem went away.  He came back to me and said I need Zalowski, he's an employee.  He put him back into the account and it went away.  The problem was that there was a space in front of his name earlier.  If you do not use an array you cannot sort.  You have to go back and forth.  For that reason you need an array.
