Error: expected unqualified-id message

[Hannahcorbin1]

Hi,
I am having trouble getting the following code to execute. Just need to figure out what I am doing wrong. Any suggestions?

error: expected constructor, destructor, or type conversion before '>>' token
error: expected unqualified-id before 'if'

#include <iostream>
using namespace std;


int units_sold;
int total_cost_wout_discount;
int discount_rate;

int main()

//Get number of units sold
	cout << "Enter amount of units sold:" << endl;
	cin >> units_sold;

//Calculate purchase before discount and input validation statement
if (units_sold > 0)
	units_sold * 99.00 == total_cost_wout_discount
else
{
	cout << "Please start program again and enter a quantity greater than zero";
}

//Determine and display final cost after %20 discount rate
if (units_sold => 10 && 19 <=)
	discount_rate = total_cost_wout_discount *.20
{
    cout << "Your final cost including 20% discount is" << total_cost_wout_discount - discount_rate << endl;
}

//Determine and display cost after %30 discount rate
else if (units_sold => 20 && 49 <=)
	discount_rate = total_cost_wout_discount *.30
{
    cout << "Your final cost including 30% discount is" << total_cost_wout_discount - discount_rate << endl;
}

//Determine and display final cost after %40 discount rate
else if (units_sold => 50 && 99 <=)
	discount_rate = total_cost_wout_discount *.40
{
    cout << "Your final cost including 40% discount is" << total_cost_wout_discount - discount_rate << endl;
}

//Determine and display final cost after %50 discount rate
else if (units_sold => 100)
	discount_rate = total_cost_wout_discount *.50
{
    cout << "Your final cost including 50% discount is" << total_cost_wout_discount - discount_rate << endl;
}

//Determine and display final cost after no discount rate
else (units_sold <= 9 && >= 1)
{
    cout << "Your total cost is" << total_cost_wout_discout <<endl;

}
return 0;

}

Normally that error means you have << going the wrong way:
std::cout >> "Other Way";

But you have some other errors:
You need a bracket here-

int main(){

and * does nothing (or at least here) what you want is *=

discount_rate = total_cost_wout_discount *=.20
