contains an assumend example of an organization (XYZ Company). The personnel department of the organization interacts with regard to the employee
managment, the job criteria, and salary behaviour of about more than 100 employees. Also they have number of terms and contitions for employees (which is given
in the programs by comment line either in // or /* ). It comprises a menu driven program, and includes number of options, procedures for each selective modules
with a complete class declaration of OOPs concept. The complete project handles two data bases as DETAILS.dat and EMP.dat. This project includes number of libraries
including different header files and their respective functions which is noted down after the source code of the project.
According to the requirements, the employer deals with certain attributes like:
emp_no - Employee number
name - Employee name
address - Employee address
dd, mm, yy - Date of birth & date of joining
city - Employee city
state - Employee state
zip - Employee Zip code
salary - Employee basic salary
grade - Employee grade according to grade calculation
emp_job - Employee job/designation
deptno - Employee department number
And the above attributes are divided into two databases as: DETAILS.dat & EMP.dat data file
The field contents of DETAILS.dat as:
int emp_no;
char name[30], address[30];
int dd, mm, yy;
char city[10], state[2], zip[10];
and the fields contents of EMP.dat as:
int emp_no;
int dd, mm, yy;
char grade[2];
char emp_job[12];
float salary;
int deptno;
This project is developed using C++ class concepts and having number of different
user defined function (UDFs) as follows:
DRAW_LINE(.....)
This function passes four parameters including three integer and one character to
draw different lines to design the screen beautiful. The character parameter draw the
ASCII character line-by-line on screen. So, for horizontal line draw this function is usefull.
DRAW_VER(.....)
The DRAW_VER(.....) function is helpful for drawing vertical lines on screen to design
either menu or program forms for data entry, modify, display, delete etc..
DRAW_BOX(.....)
This function creates different size of boxes on the screen according to the respective
parameters. Out of all the parameters they draw boxes till the limit you want.
MAIN_SCREEN(.....)
This is the main screening menu which will display your 6 different prompts and having different activities.
Each prompt is connected with different functions to perform the respective purposes. Out of all the options
the last one produces another sub-menu for modifying and deleting existing employee informations.
While handling the main menu you can press any selective number to perform the operation or press 0 (Zero) to exit from
the main menu. But it is also helpful in almost all menus that, you can press 0 (zero) to exit from the respective menu.
MENU_EDIT(.....)
This is one of the sub function which is connected from the MAIN_SCREEN() function to perform the modification and deletion operation
on employee data from DETAILS.dat and EMP.dat data file.
All the the ways the menus are perform the operation according to the employee number (emp_no) except
the "Open New Employee" of MAIN_SCREEN() function because, the "Open New Employee" form automatically creates
the employee number after a brief search to the existing employee numbers. Basically, the numbers are generating automatically, like your 'Banking Project'.
EMP_APPEND(.....)
The EMP_APPEND() function declared in both details and employee class. This function is used to append new records into both DETAIL.dat and EMP.dat data file
by passing their recpective parameters.
modify()
This function is used to display a modification screen for modifying the employee details by entering the employee number. While modifying the employee number
(emp_no) will be entered by the user and will search in both the data bases, and then the respective records can modified.
The function uses a function found_employee() to search the particular employee is exists or not. If exists then the function
display(..) will display the details of employee from DETAILS.dat and EMP.dat data file. After modifying the data it again
re-writes the same in both the data files through modify_employee(.....) and modify_salary(.....) functions respectively.
delete_employee(.....)
This is the sub-function of "Edit Employee" prompt of main menu. This function is used to delete an existing employee details from both DETAILS.dat and EMP.dat data file. This function is declared both in
details class and employee class. While in delete_employee function, you have to enter the employee number for delete! and the deleted informations will display in the screen through the function display_employee() and a prompt for delete. If you will press
'Y/y' then the records will be deleted from both DETAILS.dat and EMP.dat data file.
display_emp_list()
This function is used to display all existing employee list from DETAILS.dat and EMP.dat data file. While listing the records of all employees it used two other function
found_salary() and *found_job from employee class to displays the designation and salary of each employee.
last_emp_no(....)
This function detects the last employee number in the DETAILS.dat data file. While entering new records into data files, it will first find the last employee number for the new_employee(...) function for
generating the next employee number automatically.
found_employee(.....)
As the project operated with only the key field employee number and when the employee number entered it always checks in the data base DETAILS.dat that whether the employee is exist or not. If exists, then further
the employee can processed eiter for modify, delete, display or etc.
*return_name(...)
If their is any requirement of the employee name to display at any momemt then, this function returns the name of the employee from
DETAILS.dat data file with the parameter employee number (emp_no). This function uses emp_no as the parameter to search in the data base.
*return_address(...)
If their is any requirement of the employee address to display at any momemt then, this function returns the address of the employee from
DETAILS.dat data file with the parameter employee number (emp_no). This function uses emp_no as the parameter to search in the data base.
display_from_details(...)
This function is used to display the employee details from DETAILS.dat data file. Before displaying the name and address information, the fuction
passes emp_no as a parameter for which employee detail is to display. If the employee no. found the the related informations will display in the screen.
s
recordno(...)
This is very important function which returns the record position in the data file. While knowing the record number it will easy for modifying the existing employee details in
both DETAILS.dat and EMP.dat data files.
display(...)
This function is used to display the information related to employee number.
Because, this function passes a parameter emp_no and according the number the information is displayed.
This is a multi-declared function in class detials and employee.
send_DATA(...)
While generating a salary report, this function displays the name and address information from DETAILS.dat data file with the help of
employee number (emp_no as a parameter).
modify_employee(...)
This function is used to re-write the name and address information both in the DETAILS.dat and EMP.dat data file. The function
passes number of parameters which will be re-written in data file.
new_employee(.....)
This is the first function used for first option "Open New Employee" in MAIN_SCREEN() function. When any new employee entered into the company, the detailed
information is entered by using this function.
close_employee()
This is similar function like delete_employee(). It uses one parameter emp_no, for which employee has to delete from EMP.dat data file.
If it is true to delete then the employee salary behaviours will be deleted from EMP.dat data file.
display_employee()
This is an another option in MAIN_SCREEN() function who dipslays the existing employee lists in the screen. Also, this function uses other two function like *return_job
and return_salary for displaying job/designation and salary simultaneously with the employee name and address.
Left_clear() and Right_clear()
This two function is used to clear the existing screen from a spacified row and till a specified column. This functoin uses two parameters as int, int.
For left from a column position to till a last column. If your display/output screen divided into two halves, then the screen may clear till 39th and 79th respectively according to
the parameters of the functions.
month_salary()
This function is used to create a monthly salary slip of an employee. The user has to enter the employee number and if the employee exists in DETAILS.dat data file then, the respective screen of salary slip will be displayed and
all other benefits and deductions will calculated including income tax (as on table given before the function source code). The final net salary displays individually employee wise on screen.
modify_salary()
The function modify_salary() is used to re-write the modified record in EMP.dat data file.
When the user modifies the existing data according to the previous data, then all the fields related to EMP.dat data file
will receive through the parameters in modify_salary() function which will re-write in the previous position of EMP.dat data file.
All the way the function uses one major in-build function seekp(), which find the position of the record in the data file where the record will be
re-written. Once the position will found, then the modified record will written easily on the existing record.
found_salary()
This function is used to found the salary of a selected employee, for which receives a parameter as emp_no into the function and
returns the found salary into the display_emp_list function.
found_job()
On the same way the function also found the job/designation of a selected employee, for which recieves a parameter as emp_no into the function and
return the found emp_job into the display_emp_list function.
change_salary()
The basic aim of the function is used to change the employee salary when he/she gets any increment on basic salary.
While changing the salary in EMP.dat data file, all other information related with the employee in the data file will again
over written like modification techniques. Because while writting only one field into file the record contents may distrub or
shifted its position either backward or forward, so the key record number may changes which you won't except. Thus to avoid this type
of concurrency the user has to pass all information related to the data file again on same way like addition of new record. But here the record is
not appended but over written.
box_for_display()
This function display the employee number and the date on the screen. Also the function calls the function
display_from_details to display the informations from DETAILS.dat data file accourding to the employee number,
which is one of the parameter in both box_for_display() and display_from_details() functions.
