Question

Description: A program is needed for a third-party payroll clearinghouse that supports the following:

• Calculate employee pay feature

• Company total pay feature

The employee and company totals are stored in a text file for each individual company.

1. Create the following “input.txt” file. Each record consists of a first name, last name, employee ID, company name, hours worked, and pay rate per hour.

Maria    Brown 10 Intel   42.75 39.0

Jeffrey Jackson 20 Boeing   38.0 32.5

Bernard Smith 30 Douglas   25.0 23.25

Matthew Davenport 40 Raytheon   63.15 47.5

Kimberly Macias     50 Douglas 45.5 40.0

Amber    Daniels 60 Raytheon   62.25 44.5

Michael Lee 70 Boeing   32.0 35.5

Patricia Wright     80 Intel 40.0 32.0

Stanley Johnson 90 HealthTech 48.5 43.25

James    Miller 100 Raytheon   55.5 45.75

Linda    David 110 HealthTech 40.0 36.5

Olivia   Walker 120 Intel      61.15 51.5

Thomas   Sanders 130 Raytheon   50.25 38.5

Sophia   Foster 140 Raytheon   44.15 44.0

Ryan     Ward 150 Douglas    68.0 48.25

Karen    Hill 160 Intel      49.5 54.0

2. Each record will be saved in an instance of a CLASS called Person. The person class will be declared as follows (HINT: this should go in a file called person.h):

//begin person.h

#ifndef PERSON_H

#define PERSON_H

#include <string>

using namespace std;

class Person

{

private:

   string firstName;

   string lastName;

   int   employeeID;

   string companyName;

   float hoursWorked;

   float payRate;

public:

   Person();

   void   setFirstName(string fName);

   string getFirstName();

   void   setLastName(string lName);

   string getLastName();

   void   setEmployeeId(int id);

   int   getEmployeeId();

   void   setCompanyName(string coName);

   string getCompanyName();

   void   setPayRate(float rate);

   float getPayRate();

   void   setHoursWorked(float hours);

   float getHoursWorked();

   float totalPay();

   string fullName();

};

#endif // end person.h

3. You will need to make a separate file called person.cpp. The file person.cpp contains proper definitions for all function declarations in the header file. The first line of the file is an include statement:

#include "person.h"

Here is an example of a function definition in person.cpp:

string Person::getFirstName() {

   return firstName;

}

Note the <ret type> Classname::funcName() structure here. The “::” is referred to as a scope resolution operator. It lets the compiler know that this code is defining a function for the class Person, and not a bare function that can be used anywhere. It also lets the compiler know that the variables reference in the function can be found within that class. This is required, because they are private otherwise.

4. Make a new file called pay.cpp that includes:

• A main() function

• The #include "person.cpp" statement

• Any other necessary includes and/or helper functions

• All the additional details mentioned below

5. A vector called employees used to store the employee data when reading from the file (employees will be of the Person class). Use of the vector class (instead of an array) will ensure that your data space can grow as needed to handle any reasonable number of employees. Use of a vector is required. It should be declared in main().

6. A vector called companyNames that holds the string names of each company (companyNames will be of type string). This information will be needed to complete step 10. Use of a vector is required. It should be declared in main().

7. A function readData to read the data from “input.txt” and store it in the employees vector. NOTE: the vector needs to be passed to the function by reference and the file should be read only once in the program.

8. A function getCompanies that retrieves the company names from employees and adds them to companyNames. NOTE: both vectors need to be passed to this function by reference.

9. A function called printHighestPaid must find and output (cout) the full name, employee ID, company name, and total pay of the person who was paid the highest amount this statement. Call the function from main before exiting the program. NOTE: the employees vector needs to be passed to this function by reference. Example output:

Highest paid: Ryan Ward

Employee ID: 150

Employer: Douglas

Total Pay: $3281.00

10. A function called separateAndSave must write the payroll information to multiple text files - one for each company. Each file should be named after the company (e.g. Boeing.txt) and contain only the employees from that company. Within the file, the data should be formatted by selecting reasonable column widths for output. The float output should be truncated to 2 decimal places. The column widths do not have to match exactly. Simply pick a reasonable number of characters for each (20-30 for names, etc). The output should also have the total pay for each company. NOTE: both vectors need to be passed to this function by reference.

Additional Notes:

• No global variables are allowed

• Do not change function/class/vector/file names or function declaration

• You may only call the open file method to read the file one time in the program
