Question

1. Create a class tuck shop with following data members:

2. String Owner

   String Food_Items[100]

   Double Price [100]

   Int Quantity [100]

                  Note:

3. • All arrays are open ended. It is not necessary that they are completely filled.
   • All three arrays will work in synchronization with each other i-e the item at index 0 will have its price in Price array at index 0 and quantity at index 0 of Quantity array.

4. Methods:

   Two Constructors (default, four-argument)

   set for Owner , get for Owner

   display()

   addFooditem (?)                                       // Adds a food item, its price, and its quantity in the first available free slot in Food_Items, price and quantity array

   buy (?)                                                        //decrement quantity if more than one item is present. If only one item is present then the item should be removed from Food_Item array.

   compareTwoShops (   ? )                         //compare two shops and return the shop with more items.

   compareOwner (   ?    )                                 //compare owners of two shops and return true if both owners are           same and false otherwise.

   Note:

   Do not add data members at your own.

   Declare data as private

   Do not create set and get methods for array data members as they cannot be updated independent of each other.

   ‘?’ means that you need to identify the arguments if they are required.

   Runner:

   In the runner create two objects and all the above function.

5. in java or in C#
