Need help with this While statement

Heres the statement, will explain problem after

Code:

//Lab 02 - 4.16 Salary Calculator

#include <iostream>

using std::cout;
using std::cin;
using std::endl;

int main()
{
    int hoursWorked = 0;
    int hourlyRate = 0;
    int salary = 0;
    
    cout << "Enter hours worked (-1 to end): ";
    cin >> hoursWorked;
    cout << "Enter hourly rate of employee (00.00): ";
    cin >> hourlyRate;
    
    while(hoursWorked > -1)
    {
                      if(hoursWorked <= 40)
                      {
                      salary = hoursWorked*hourlyRate;
                      cout << "Salary is: " << salary << endl;
                      }
                      else
                      {
                      salary = (40 * hourlyRate) + (hoursWorked - 40)*hourlyRate;
                      cout << "Salary is: " << salary << endl;
                      }
    cout << "Enter hours worked (-1 to end): ";
    cin >> hoursWorked;
    cout << "Enter hourly rate of employee (00.00): ";
    cin >> hourlyRate;
    }
    
    system("pause"); 
	return 0;
}

The problem I'm getting is that after entering the hoursWorked and hourlySalary it constantly repeats 'Enter hours worked (-1 to end): Salary is 390.00' over and over untill I turn the program off, just getting started back after not programming for a while so its probably a stupid mistake, please help! :P

You may wish to search for how to clean the input buffer. Oh so common issue. Oh so trivial solution.
You should find an answer in no time.

Just before you posted this reply I found out another way to do it, I used a do...while statement instead of while so it would check for the condition afterwards, thanks for the suggestion though, if I ever get stuck in a situation where I MUST use while, I'll try that

Really? I wouldn't think it would have anything to do with the loop itself, but with the input buffer problem.
