Problem statement:
Create a program that will read an employee file, as below,
Employee num Department PayRate Exempt Hours worked
101 41 8.11 Y 49
722 32 7.22 N 40
9876 23 9.99 N 39
666 1 66.66 Y 66
create a output payroll register file, and then search the newly created file(using binary
search algorithm)
Code:
The output file, or payroll register file, ( user chooses name ) is to have the following data
( each employee on one line ) a. Employee number ( left justified )
b. Department
c. Pay Rate d. Exempt e. Hours Worked f. Base Pay ( pay rate * hours worked ) g. Overtime pay h. Total pay
Overtime pay is calculated only for nonexempt employees.
An employee is exempt if a “Y” appears in the exempt column. Overtime is paid for all hours worked over 40. Overtime multiplier is 1.5. If an exempt employee works over 40 hours, the employee is only paid for 40 hours of work.
Now ask the user if they wish to search the payroll register file.
If yes, load the employee records from the register file into an array of struct Assume there are at most fifty records.
The user will be prompted for an employee number,
Do a binary search on the array of employee structs, determining if the employee
is in the database.
If employee is in the database, print employee info,
If not, state so with an informational message. Repeat as long as the user wishes.
The struct is to be named employRec and is to have at least 7 fields
The array is to be named empArray
The struct is to be declared in a file called employee.h along with function
prototypes
The remaining functions for input/output file are to be in the files_ops.h and
files_ops.cpp. Function prototypes should be in the respective header file.
Function main() is to be in a separate file called main.cpp
Here's a sample search
Please enter an employee number : 666
The record of employee with id 666 is
Department: xyz
PayRate $xx.xx
Exempt: Y
Hours Worked : xxx
Base Pay :$xxxx.xx
Overtime : $xxxx.xx
Total Pay: $xxx.xx
Do you wish to search database?
Please enter an employee number : 129
Employee seems not to exist
You are to create a project/file for this lab named Lab11for the project name and lab11_driver.cpp for the driver.
A sample text file ( “emp_data.txt” ) and binary search program is provided. Check email attachment to see the file your program will read. Download and copy the sample text file in your hard drive.
Open the file in a function – error check
