Explanation

Dependencies:
- This program uses the SFML library for creating the graphical user interface (GUI). Ensure you have SFML
  
  Advertisement
  
  installed and properly linked in your project.
Item Structure:
- Item struct holds the name and graphical representation (shape) of an item.
Draw Items Function:
- drawItems(RenderWindow& window, const vector<Item>& items)
  
  Advertisement
  
  : Clears the window and draws all items from the vector.
Main Function:
- Initialization: Sets up the SFML window and font.
- Event Handling: Checks for user inputs to perform CRUD operations.
  - Add Item (A key): Creates a new item with a green rectangle shape and adds it to the list.
  - Remove Item (R key): Removes the most recently added item.
  - Update Item (U key): Changes the color of the most recently added item to red.
  - Display Items (D key): Shows the names of all items in the window.
Running the Application:
- The application continues to run until the window is closed. During runtime, pressing the keys will add, remove, update, or display items as specified.

Note:

The program uses SFML for GUI, so ensure that SFML is installed and linked correctly.
Font file arial.ttf must be present in the working directory or specify the path to a valid font file.
