Example #include // include io library using namespace std; int main() { // Begin main function int cookieCost = 1; // cost of 1 cookie int numCookiesPurchased; double subtotal; cout << "Number of Cookies? "; // prompt cin >> numCookiesPurchased; // read from keyboard subtotal = numCookiesPurchased * cookieCost; cout << "Cookies: "; cout << numCookiesPurchased << " at $"; cout << cookieCost << " each " << endl; cout << "Subtotal = $" << subtotal << endl; return 0; // end program } // End main function Using this above example: Create a tax rate variable if tax is: .05 (not 5%) What type should it be? What is a good name? • Read in the tax rate Calculate & print the tax Print the total
