Structs and Arrays to program a menu

[chandeliho]

Entire code so far provided but I need help with the showmenu function. Once it's established that a certain item has been selected (thus set to "true"), what then? Afterward I need to be able to display the bill listing each item and its cost and the total cost along with tax.

#include <iostream>
#include <fstream>
#include <iomanip>
#include <string>

using namespace std;
const double TAX = .08;

struct menuItemType
{
	string menuItem;
	double menuPrice;
	bool selected;
};

void getdata(ifstream& infile, menuItemType menu[]);

int main()
{
	menuItemType menu[20];
	
	ifstream infile;
	infile.open("menu.txt");

	getdata(infile, menu);
	//call showmenu
	//call printcheck

	infile.close();

	system("pause");
	return 0;
}

void getdata(ifstream& infile, menuItemType menu[])
{
	int i = 0;
	do
	{
		getline(infile, menu[i].menuItem);
		infile >> menu[i].menuPrice;
		infile.get();
		menu[i].selected = false;
		i++;
	} while (infile);
}

void showmenu(menuItemType menu[])
{
	int choice;
	int i;

	cout << "Menu Choices" << endl;
	cout << " 1. Plain Egg			$1.45" << endl;
	cout << " 2. Bacon and Egg		$2.45" << endl;
	cout << " 3. Muffin			$0.99" << endl;
	cout << " 4. French Toast		$1.99" << endl;
	cout << " 5. Fruit Basket		$2.49" << endl;
	cout << " 6. Cereal			$0.69" << endl;
	cout << " 7. Coffee			$0.50" << endl;
	cout << " 8. Tea				$0.75" << endl;
	cout << " 9. Finished Ordering" << endl;
	cout << endl;

	do
	{
		cout << "Enter a choice (1-8): ";
		cin >> choice;
		
		menu[choice-1].selected = true;
			if (menu[i].selected == true)
				{ 
					
				}
	} while (choice != 9);
}

void printcheck()
{

}
