Need help with restaurant homework

PhoenixBlain (6)
So I'm cluelessly lost. I'm not asking for someone to do my homework for me, I just kinda need a pointer in the right direction. The homework assignment I'm working on prompts:

"Write a program to help a local restaurant automate its breakfast billing system. The program should do the following:

Show the customer the different breakfast items offered by the restaurant (You may be as creative as you like....it doesn't have to be breakfast items and you can name your restaurant anything you like).
Allow the customer to select more than one item from the menu and multiple items of the same type (e.g., the customer may desire a Bacon and Egg sandwich, 2 Muffins, and a cup of Coffee).
Calculate and print the bill.
Assume that the restaurant offers the following items (the price of each item is shown to the right of the item)"

And my requirements include:

"A struct menuItemType with two components:
menuItem of type string and menuPrice of type double.
Function getData:
This function loads the data from a text file into the array menuList.
Function showMenu:
This function shows the different items offered by the restaurant and tells the user how to select the items.
Function printCheck:
This function calculates and prints the check. (Note that the billing amount should include a 5% tax.)"

So the part that I'm stuck at is reading in the information. It seems I have everything else fine (I could be horribly wrong though), but I cannot for the life of me figure out how to read in strings from the .txt files and input them into the menu items. Any help would be appreciated.

Hello PhoenixBlain,

When reading the file replace the for loop with:
1
2
 
while (std::getline(inFile, menuData[i]))
	i++;
This will allow you you to read any size file.

In the "printCheck" function you might like this:
1
2
3
4
5
6
7
8
9
10
11
12
13
14

void printCheck(menuItemType menuList[], int menuOrder[], int menuItems)
{

	double checkTotal = 0;
	double checkTax = 0;
	const double TAX = .05;

	std::cout << std::fixed << std::showpoint << std::setprecision(2);

	cout << "Thanks for eating at Bob Evans! "
		<< "Customer check: " << endl << endl;

	for (int i = 0; i < menuItems; i++)
	{
		if (menuOrder[i] > 0)
		{
			cout << /*setprecision(3) <<*/ setw(20) << left << menuList[i].menuItem
				<< " $" << right << std::setw(5) << (menuList[i].menuPrice * menuOrder[i]) << endl;
			checkTotal += (menuList[i].menuPrice * menuOrder[i]);
		}
	}

	checkTax = checkTotal * TAX;
	checkTotal += checkTax;

	cout << setw(21) << left << "Tax" << '$' << right << std::setw(5) << checkTax << endl
		<< setw(21) << left << "Total" << '$' << right << std::setw(5) << checkTotal << endl;
}
The "showpoint" in line 8 will print ".00" if it shows up.

I also put lin 8 in the "showMenu" function.

Hope that helps,

Andy

Thanks Andy, you were a huge help! Also, I figured out the major problem. I had forgot to put a comma between item6 and item7

1
2
 
string menuData[8] = {item1, item2, item3, item4, item5, item6
	                      item7, item8};


Very annoyed with myself lol.

Hello PhoenixBlain,

You are welcome.

Your missing comma was a problem, but while I was working on the program I did this:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
23
24
25
26
27
 
void getData(menuItemType menuList[])
{
	size_t i{};

	//string item1, item2, item3, item4, item5, item6, item7, item8;  // <--- Not needed.

	string menuData[8]; // { item1, item2, item3, item4, item5, item6, item7, item8 };

	ifstream inFile;

	inFile.open("menu.txt");

	if (!inFile)
	{
		cerr << "Unable to open file menuText.txt";
		exit(1);
	}

	while (std::getline(inFile, menuData[i]))
		i++;

//for (int i = 0; i <= 8; i++)
	//{
	//	menuText >> menuData[i];
	//}

	inFile.close();
You do not need line 5 and the uncommented part of line 7 will create an array of eight empty strings. There is no need to initialize line 7.

Hope That helps,

Andy
