C++ program help

[bigstuff1988]

Good Afternoon,

I am currently in a C++ course and I am having problems with one of my assignments. The question is below (number 4), and then what I have is below that. If anyone can provide some assistance to what I am doing wrong, it will be greatly appreciated.

3. Workers at a particular company have won a 7.6% pay increase retroactive for 6 months. Write a program that takes an employee's previous annual salary as input, and outputs the amount of retroactive pay due the employee, the new annual salary, and the new monthly salary. Use a variable declaration with the modifier const to express the pay increase. Your program should allow the calculation to be repeated as often as the user wishes.

4. Modify your program from Programming Project 3 so that it calculates the retroactive salary for a worker for any number of months, instead of just 6 months. The number of months is entered by the user.

What I currently have and the error I am getting:

#include <iostream>
using namespace std;
const float retroactivepay = 1.076f;

int main()
{
int current_salary, new_annual_salary, retroactive_pay, new_monthly_salary, number_of_months;

cout << "Press return after entering a number.\n";
cout << "Enter your current salary?: ";
cin >> current_salary;
cout << "Enter the number of months you wish to calculate your retroactive pay: ";
cin >> number_of_months;

new_annual_salary = current_salary * 1.076;
retroactive_pay = (new_annual_salary - current_salary) / 2;
new_monthly_salary = retroactive_pay * number_of_months;

cout << "Your new annual salary is: ";
cout << new_annual_salary;
cout << "\n";

cout << "The amount of retroactive pay due to you is: ";
cout << retroactive_pay;
cout << "\n";

cout << "Your new monthly salary is: ";
cout << new_monthly_salary;
cout << "\n";

return 0;
}


Error:

Once again, if anyone can provide some help it will be greatly appreciated.

If your whole program is in one (cpp) file, then why are you linking three object files?
