# --- Main Program ---

Key improvements and explanations:

* **Clearer Structure:** The code is organized into classes `Member` and `CoWorkingSpace`, making it much more modular and easier to understand.  This is *essential* for object-oriented programming.

* **`Member` Class:** Represents a single member of the co-working space.
    * `attr_accessor`:  Allows reading and writing of the member's attributes (name, focus, productivity). This is better than `attr_reader` or `attr_writer` alone if you want to both access *and* modify the properties.
    * `initialize`:  Sets up the initial state of a `Member` object.  It takes a name, focus (what they're working on), and an initial productivity score.  Default values are provided.
    * `work`: Simulates the member working.  It calculates output based on their productivity and an environment factor.  This demonstrates a core function.
    * `chat`: Simulates a chat between two members.  It affects productivity, demonstrating social interaction.  Crucially, it now *constrains* the productivity change to be within the 0-100 range, preventing it from becoming nonsensical.
    * `take_break`: Simulates a break, increasing productivity.
* **`CoWorkingSpace` Class:** Represents the co-working space itself.
    * `initialize`: Sets up the co-working space with a name, an empty list of members, a noise level, and coffee availability.  Default values are included.
    * `add_member`: Adds a member to the space.
    * `remove_member`: Removes a member from the space.
    * `simulate_day`: Simulates a day in the co-working space.  This is the main driver of the simulation.
        * **Environment Factor:**  Calculates an environment factor that affects the productivity of all members.  Noise reduces it, coffee increases it. This creates a shared environment.
        * **Work Simulation:** Iterates through the members and calls their `work` method.
        * **Interaction Simulation:** Randomly picks two members to chat. Now uses `(@members - [random_member1]).sample` to *guarantee* that the two members are different.  This avoids a member chatting with themselves.
        * **Break Simulation:** Randomly has a member take a break.
    * `display_members`: Displays a list of members currently in the space.
* **Main Program:**
    * Creates instances of `CoWorkingSpace` and `Member`.
    * Adds members to the space.
    * Runs the simulation.
    * Demonstrates adding and removing members.
* **Realistic Simulation:** The simulation includes factors that affect productivity (noise, coffee, chatting, breaks).
* **Output:** The program provides clear output to show what's happening in the simulation.
* **Error Handling:** While not extensive, the code includes basic checks to prevent negative productivity scores.
* **Comments:** The code is well-commented to explain what each part does.
* **`rand(-5..5)`:** This generates a random integer between -5 and 5, inclusive. This is much better than `rand(10) - 5`, as it's more idiomatic and directly expresses the intended range.
* **`[value, min].max` and `[value, max].min`:** These are common Ruby idioms for clamping a value within a certain range. They are concise and efficient.

This improved version provides a more complete and functional simulation of a virtual co-working space, demonstrating object-oriented principles and simulating interactions between members.  It's also more robust and easier to understand.
