#include<cstdlib>
#include<iostream>

using namespace std;

void menu(int&);
double sizeChoice(int&);
double cream();
double sugar();

int main()
{
   double totalCost = 0;
   int sizeCoffee = 1;
   char addToOrder = 'y';
   int smallSold =0;
   int mediumSold = 0;
   int largeSold = 0;

   while (addToOrder == 'y' || addToOrder == 'Y')
   {
       menu(sizeCoffee);
      
       totalCost += sizeChoice(sizeCoffee);
       cout << "Would you like to add to your order (Y/N):";
       cin >> addToOrder;
   }

   cout << endl << "Reciept: " << endl;
   cout << "Total Cost: " << totalCost << endl;

   cout << endl << endl;
   system("Pause");
   return 0;
}

void menu(int &sizeCoffee)
{
   do
   {
       cout << "What size coffee would you like?" << endl;
       cout << "Press 1 for small." << endl;
       cout << "Press 2 for medium." << endl;
       cout << "Press 3 for large." << endl;
       cout << "Your selection: ";
       cin >> sizeCoffee;
       if (sizeCoffee < 1 || sizeCoffee > 3) cout << "INVALID SELECTION" << endl;
   } while (sizeCoffee < 1 || sizeCoffee > 3);
}

double sizeChoice(int &sizeCoffee)
{
   const double SMALL_CUP = 1.75;
   const double MEDIUM_CUP = 1.90;
   const double LARGE_CUP = 2.00;

   switch (sizeCoffee)
   {
       case 1:
           return SMALL_CUP;
       break;
       case 2:
           return MEDIUM_CUP;
       break;
       case 3:
           return LARGE_CUP;
       default:
           return 0;
   }
}
