This is an assignment for my c++ class im taking.

#include <iostream>
#include <fstream>

using namespace std;

const int NAMESIZE = 50, DATE = 25;

struct inven
{
	char name[NAMESIZE];
	int qnty;
	double wholeCost;
	double retailCost;
	char date[DATE];
};

void displayMenu();
void addRecord(fstream &);
void displayRecord(fstream &);
void modifyRecord(fstream &);



int main()
{
	fstream myFile;
	int choice = 0;
	
	displayMenu();
	cin >> choice;

	while(choice >= 1 && choice <=3)
	{
		switch (choice)
			
			case 1:
				addRecord(myFile);
				break;

			case 2:
				displayRecord(myFile);
				break;
			
			case 3:
				modifyRecord(myFile);
				break;
	}

	cin.ignore();
	cin.get();

	return 0;
}

void displayMenu()
{
	cout << "1: Add new records";
	cout << "\n2: Display a record";
	cout << "\n3: Change a program\n\n";
}

void addRecord(fstream &file)
{
	char answr = 'Y';
	inven Inventory;

	file.open("Inventory.txt", ios::app | ios::binary);

		do
		{
			cout << "Item name: ";
			cin >> Inventory.name;
			cout << "\nQuantity: ";
			cin >> Inventory.qnty;
			cout << "\nWholesale Cost: ";
			cin >> Inventory.wholeCost;
			cout << "\nRetail Cost: ";
			cin >> Inventory.retailCost;
			cout << "\nDate added to inventory: ";
			cin >> Inventory.date;

			file.write(reinterpret_cast<char *>(&file), sizeof(file));

			cout << "\n\nDo you want to add another record:\n<y/n>";
			cin >> answr;

		}while(answr == 'y' || answr == 'Y');

		file.close();
}

void displayRecord(fstream &file)
{
	inven Inventory;

	file.open("Inventory.txt", ios::in | ios::binary);

		file.read(reinterpret_cast<char *>(&file), sizeof(file));

		while(!file.eof())
		{
			cout << Inventory.name << "\n" << Inventory.qnty << "\n" << Inventory.wholeCost
				 << "\n" << Inventory.retailCost << "\n" << Inventory.date << "\n";

			file.read(reinterpret_cast<char *>(&file), sizeof(file));
		}

		file.close();
}

void modifyRecord(fstream &file)
{


}

Sorry, copy pasting the code ruined the format alittle, but the main gist is there.

I cant figure out why, but when I try to compile it is telling me that case 2 and case 3 are illegal cases. Please help!
