#include <iostream>
#include <conio.h>
using namespace std;

class Employee
{
string name;
double hourwork, wage, netsal;
public:

void getEmployee(string &Name, double &hourWork, double &Wage)
{
name = Name;
hourwork = hourWork;
wage = Wage;
netsal = wage * hourwork ;
}

void calculateGrossPay()
{
double ot, sal;
if(hourwork <= 40)
{
sal = hourwork*wage;
}
else
{
sal = 2000;
}
}

void printEmolyeePayment()
{
cout << "Status of Employee : "<< name <<"Salary of Empoloyee : "<<netsal;
}
};

int="" main()
{
="" string="" name;
="" double="" hourwork,="" wage,="" netsal;
="" char="" flag="y" ;

="" grosspay;
="" int="" i="0;

" while(flag="='y')
" {
="" cout="" <<="" "\nenter="" employee="" detail\n";
="" "status="" of="" :="" ";
="" cin="">> name;
cout << "Work Hour Of Employee : ";
cin >> hourwork;
cout << "Rate Per Hour Of Employee : ";
cin >> wage;
cout << netsal;

}
return 0;
}

What I have tried:

First I tried if else but did'nt work and changed the code 6th time still it does not give the result according to the question below:
Q.No.1: A company pays its employees on a weekly basis. The employees are of two types:
1. Salaried Employees 2. Hourly Employees
Salaried employees are paid with a fixed weekly salary, regardless of the number of hours they worked.
Fix week salary
is
2000 / w
Hourly employees are paid by the hour and receive overtime pay for all hours worked in excess of 40 hours. If they work less than 40 hours then their salary will be:
Salary = wage*hours
If they work more than 40 hours their salary will be calculated using the given formula:
Salary = (40*wage) +((hours-40)*wage*1.5)
Where wage per hour will be 400 PKR.
The company wants to implement a C++ program that performs its payroll calculations. You are required to write C++ program to implement the above mentioned concept using function overloading.
Sample output
Please enter employee status
Hourly Employee
Please enter work hours:
:
30
Your total salary is
12000
