1. where is menuItemList object declared?

2. why all those useless lines that access the structure but does nothing with them? For example: menuItemList.BaconandEggs; If it is supposed to be setting them to 0 -- it doesn't.

struct menuList //Define struct menuList with members { string Eggs; string BaconandEggs; string Muffin; string FrenchToast; string FruitBasket; string Cereal; string Coffee; string Tea; string price: };

What are these variables supposed to contain? I suspect that you do not want to write out your complete menu in a struct, that would achieve very little except for a very long tedious program.
Remember: a struct is like a template for the type of information you want to store - Do not pre-empt the actual data it is going to contain!

Also, I suspect you want to use a numerical type for price.void getData();
void showMenu();
void printcheck();
OK - here you have 3 forward declarations of functions, but their definitions are inside your main() function - this is wrong, they must be declared outside main(), either before or after it. menuItemList.Eggs; //Access a struct member components
This line is doing nothing, letalone accessing anything, what do you intend this line to do? menuItemList.price = 0.0;
This is an error. assuming you mean "menuItem price" - its a string - you must change price to float, or preferably, double to do this. void showMenu();
cin >> menuItemType.Eggs >> menuItemType.BaconandEggs;
cin >> menuItemType.Muffin;
cin >> menuItemType.FrenchToast;
cin >> menuItemType.FruitBasket;
cin >> menuItemType.Cereal;
cin>> menuItemType.Coffee;
cin >> menuItemType.Tea;
I Already mentioned that this function must be declared outside main(). Aside from that - What are you asking your users to input? The name "ShowMenu" is very misleading and confusing - it doesn't show or output anything!
Quite the opposite, in fact - it asks for user input. Maybe GetMenuContents() would be a more appropriate name here.

think more carefully about the actual data you wish to store. storing price or other numerical information in a string is quite useless.

I suspect you'd be better of re-designing your data structures. In real terms, every item on a restaurant menu is a seperate entity with unique properties. These entities do not share any information with each another, so why relate them in a struct?

struct MenuEntry
{
  std::string name;
  double price;
}

A menu is a collection or list of all these entities. a C++ container such as "list" or "vector", would be well suited to the task of grouping all your entries together, and forming your Menu.

i have a case study....
my prof said that we should display 10 random numbers without reaping the same number for example the screen will print numbers from 0-9 at this order

1 6 7 5 2 3 4 9 8 0

then when we exit the program it should pritn another random number... plss help i needed it very badly :sad: :sad: :sad:

OK... so, show us how far you've gotten with your program...
