int region = 1;

int totRegSales = 0;

while (region < 3)

{

cout << "First sales amount for Region "

<< region << ": ";

cin >> sales;

while (sales > 0)

{

totRegSales = totRegSales + sales;

cout << "Next sales amount for Region "

<< region << ": ";

cin >> sales;

} //end while

cout << endl << "Region " << region << " sales: $"

<< totRegSales << endl << endl;

region = region + 1;

totRegSales = 0;

} //end while

cout << "End of program" << endl;

Question 13 options:

a.	int totRegSales = 0;
b.	while (region < 3)
c.	cin >> sales;
d.	while (sales > 0)
