I'm using visual studio community edition to run this code, I'm receving 6 errors that I cannot figure out how to fix.

What changes do I need to make to fix it?

Here is the code I'm using:

main.cpp

#include "InventoryItem.h" #include "CashRegister.h" #include #include #include #include

using namespace std;

const double SALES_TAX = .06, //current sales tax PROFIT_MARGIN = .3; //to hold the markup percentage

InventoryItem menuCase(InventoryItem, CashRegister&); void menu(); void greet(); //end prototypes

int main() { greet();

menu();

cout

void greet() { cout

void menu() { int menuOption; char moreItems='Y'; const int SIZE=8; InventoryItem items[SIZE]={ InventoryItem("Loki Earrings", 8.95, 2), InventoryItem("Cpt. America Pendant", 4.95, 8), InventoryItem("Iron Man Gloves", 8.95, 6), InventoryItem("Black Widow Earrings", 12.95, 5), InventoryItem("Thor Earrings - Mjolnir", 12.95, 9), InventoryItem("Hulk/Banner Earrings", 16.95, 7), InventoryItem("Hawkeye Pendant", 7.95, 20), InventoryItem("Loki Helmet Charm", 6.95, 12) }; CashRegister reg1;

while (moreItems='Y') { cout

for (int count=1; count

cout

cout > menuOption;

while (menuOption > menuOption; } while (menuOption > SIZE) { cout > menuOption; }

switch (menuOption) { case 1: items[menuOption-1]=menuCase(items[menuOption-1], reg1); break; case 2: items[menuOption-1]=menuCase(items[menuOption-1], reg1); break; case 3: items[menuOption-1]=menuCase(items[menuOption-1], reg1); break; case 4: items[menuOption-1]=menuCase(items[menuOption-1], reg1); break; case 5: items[menuOption-1]=menuCase(items[menuOption-1], reg1); break; case 6: items[menuOption-1]=menuCase(items[menuOption-1], reg1); break; case 7: items[menuOption-1]=menuCase(items[menuOption-1], reg1); break; case 8: items[menuOption-1]=menuCase(items[menuOption-1], reg1); break; default: break; } //end switch

if (menuOption == 0) { cout > moreItems; moreItems = toupper(moreItems); } } //end moreItems while }; //end menu function

InventoryItem menuCase(InventoryItem inventitem, CashRegister &rega) { int quantity;

cout >quantity;

while (quantity >quantity; } while (quantity > inventitem.getUnits()) { cout >quantity; }

if (quantity > 0) { if (quantity 0 else { //for if the quantity is 0 cout

return inventitem; };

17. Cash Register Design a cashRegister class that can be used with the Inventoryitem class discussed in this chapter. The cashRegister class should perform the following: 1. Ask the user for the item and quantity being purchased. 2. Get the item's cost from the InventoryItem object. 3. Add a 30% profit to the cost to get the item's unit price. 4. Multiply the unit price times the quantity being purchased to get the purchase sub- total. 5. Compute a 6% sales tax on the subtotal to get the purchase total. 6. Display the purchase subtotal, tax, and total on the screen. 7. Subtract the quantity being purchased from the onHand variable of the InventoryItem class object. Implement both classes in a complete program. Feel free to modify the InventoryItem class in any way nec Input Validation: Do not accept a negative value for the quantity of items being purchased. essary
