Task
Online Shopping System
Using classes and arrays, the team will develop a set of functions for an online
shopping system. The system is represented by the following structure:
1- Class Item having the following private attributes: (ID, name, quantity, price) and
the following public methods:
- Constructors (default, parameterized, and copy)
- Setters & Getters
- Operator overloading for the ==, +=,-=, >> and <>
Note that the ID member variable is not entered or read from the user. It is
automatically set by the class as a serial ID starting with the first item of ID 1 and
incrementing with every new object.
2- Class Seller having the following private attributes: (name, email, items,maxItems),
where items is a dynamic array of objects of type Item with the size maxItems. The
class has the following public methods:
- Constructor (parameterized)
- Operator overloading for the >> and <>
- Add An Item.
- This will take an Item object as a parameter:
- If the item already exists in the seller's items you will increase the item’s
quantity by the quantity of the parameter item using the (+=) in Item class,
and the price of the parameter object will be ignored. Use the == operator
for this where an item is equal to another if they have the same name.
- Else you will add it to the seller’s items.
- The member function should return a boolean that indicates the successful
addition of item, which will succeed if there is a place in the array and fail
otherwise.
- Sell An Item.
- This will take an item name and a quantity as parameters
- If the quantity is <= item’s="" quantity="" you="" will="" decrease="" it="" from="" item="">
the (-=) in Item class.
- Else you will print him “There is only {quantity} left for this item”.
- The member function should return a boolean which is true if the item was
found, false otherwise.
- Print Items.
- This will print all the item information for the seller.
- You will print each item using the (<)>
- Find an Item by ID
- This returns an Item object (or a pointer to Item) with the specified ID if
there is an item with such ID.
- Destructor
3- In the main function,
● First you’ll ask the seller to input his details using the (>>) operator in Seller
class.
● Then you’ll ask him for his store capacity (maxNumberOfItems).
● Then you will show him a menu to choose from which have the following
options:
1. Print My Info.
a. This will print the seller info using the (<) operator="" in="" seller="">
2. Add An Item.
3. Sell An Item.
4. Print Items.
5. Find an Item by ID
6. Exit
