Question

Using C++ language, create a program that uses a struct with array variables that will loop at least 3 times and get the below information:

First Name

Last Name

Job Title

Employee Number

Hours Worked

Hourly Wage

Number of Deductions Claimed

Then, determine if the person is entitled to overtime and gross pay. Afterwards, determine the tax and net pay. Output everything to the screen. Use functions wherever possible.

Bonus Points:

Use an input file to read in an unknown number of records into your program: +5 points

Use Vectors instead of arrays in your struct: +5 points

employee.cpp file

#include<iostream>
#include<vector>
#include<fstream>

using namespace std;

//global variables for jobTime
const int jobTime = 5;
//global variables for tax rate
const double tax  = 1;


//Employee definition of struct type

    int empNo;

//display() definiton for displaying the details of all employees
void display(vector<Employee>&emp){

        cout<<"\nGross Pay: "<<grossPay;
        cout<<"\nTax: "<<tax<<"%";
        //calculating net pay
