Hello XzainKarrito,

You may find something useful here http://www.cplusplus.com/forum/beginner/277265/ Not the same program, but may help.

When going over your code it is very hard not to notice:

void getData(ITEM& menuList)  // <--- Changed.
{
    menuItemType plainEgg;
    menuItemType baconEgg;
    menuItemType muffin;
    menuItemType frenchToast;
    menuItemType fruitBasket;
    menuItemType cereal;
    menuItemType coffee;
    menuItemType tea;


    plainEgg.menuItem = "Plain Egg";
    plainEgg.menuPrice = 1.45;
    baconEgg.menuItem = "Bacon and Egg";
    baconEgg.menuPrice = 2.45;
    muffin.menuItem = "Muffin";
    muffin.menuPrice = 0.99;
    frenchToast.menuItem = "French Toast";
    frenchToast.menuPrice = 1.99;
    fruitBasket.menuItem = "Fruit Basket";
    fruitBasket.menuPrice = 2.49;
    cereal.menuItem = "Cereal";
    cereal.menuPrice = 0.69;
    coffee.menuItem = "Coffee";
    coffee.menuPrice = 0.50;
    tea.menuItem = "Tea";
    tea.menuPrice = 0.75;

    menuList[0] = plainEgg;
    menuList[1] = baconEgg;
    menuList[2] = muffin;
    menuList[3] = frenchToast;
    menuList[4] = fruitBasket;
    menuList[5] = cereal;
    menuList[6] = coffee;
    menuList[7] = tea;
}

Changing the struct to:
1

constexpr int MAXSIZE{ 8 };  // <--- You can make more use of it here.

//struct for menuItemType
struct menuItemType
{
    string menuItem;
    double menuPrice;

    void SetValues(std::string item, double price)
    {
        menuItem = item;
        menuPrice = price;
    }
};

using ITEM = menuItemType[MAXSIZE];

void getData(ITEM& menuList);

The function then becomes:
1
2
3
4
5
6
 
void getData(ITEM& menuList)
{
    menuList[0].SetValues("Plain Egg", 1.45 );
    menuList[1].SetValues("Bacon and Egg", 2.45);
    // <--- The rest here.
}

Or againtry has another alternative.

This is the output I get:

Welcome to Johnny's Resturant
You can make up to 8 single order selections
[ 1]Plain Egg$1.45
[ 2]Bacon and Egg$2.45
[ 3]Muffin$0.99
[ 4]French Toast$1.99
[ 5]Fruit Basket$2.49
[ 6]Cereal$0.69
[ 7]Coffee$0.5
[ 8]Tea$0.75
Do you want to make selection Y/y (Yes), N/n (No):
y
Enter item number
1
Do you want to make selection Y/y (Yes), N/n (No):
y
Enter item number
2
Do you want to make selection Y/y (Yes), N/n (No):
y
Enter item number
3
Do you want to make selection Y/y (Yes), N/n (No):
n
Thanks for eating at Johnny'sCustomer check:
Plain Egg $1.45
Bacon and Egg$2.45
Muffin    $0.99
Tax           0.245
Total         5.13

You really need to make it look better.

I think it is required that you output the line "Do you want to make selection Y/y (Yes), N/n (No): ". If you leave off the "endl", better to prefer using (\n), the input will be on the same line as the prompt.

And now it shows what it is supposed to.
