Here's the whole thing. There are some parts of it that I find kind of odd, such as asking the user if they want to order at the beginning and therefore manipulating the boolean variable, but I have to do that because I have to make my output look identical to a screen shot my teacher posted, which I have done. I've already turned it in so I'm mainly posting the whole thing in case anyone's curious and to get any input about things I could learn on my own to do things better as I'm learning. If posting whole programs like this is taboo let me know and I won't do so in the future.
Code:

// Structure for each menu item.
struct menuItem
{
string name;
double price;
};
// Function prototypes
void getData(ifstream& dataFile, menuItem menuList[]);
void showMenu(menuItem menuList[]);
void printCheck(menuItem menuList[], int orderList[]);
int main()
{
// Declares two arrays for computations and to store file data.
menuItem menuList[MENU_SIZE];
int orderList[MENU_SIZE]={0};
ifstream dataFile;
int menuChoice;
char yesNo;
bool decision;
// Opens necessary CSV file
dataFile.open("breakfast.csv");
// Checks to make sure file opened, displays message and ends program
// if not.
if (!dataFile)

cout << "File failed to open. Ending program." << endl;

}
// Calls functions to get data from csv file and display menu, respectively.
getData(dataFile, menuList);
